Report from the Plant Breeding and Genetics Section of the JointFAO/IAEA Division

The year 1984 saw the 20th Anniversary of the Joint FAO/IAEADivision and its official celebration in the presence of FAO DirectorGeneral, Dr. E. Saouma, at the IAEA General Conference in October. Ascientific seminar and an exhibition demonstrated to the delegates someof the technology achievements derived from the joint programme betweenFAO, IAEA and their Member States.

Most relevant for the future will be the establishment of in-vitroculture facilities at the FAO/IAEA Agricultural BiotechnologyLaboratory Seibersdorf. They have already been in use for the 3rdFAO/IAEA Interregional Training Course on the Induction and Use ofMutations in Plant Breeding, 3 April - 18 May 1984. 20 trainees, allfrom different countries were trained. In addition to training inmutation induction the laboratory can now offer training in in-vitroculture of maize, garlic, alfalfa, pea, banana, cassava and cocoa.

3 - 7 March 1984 research contract and agreement holders of theFAO/IAEA Co-ordinated Research Programmes on the Use of InducedMutations for Improvement of Grain Legume Production in South East Asia(RCA) and on Induced Mutations for Disease Resistance in Grain Legumesmet jointly at the Nuclear Institute for Agriculture and Biology,Faisalabad, Pakistan for their 4th research co-ordination meeting.

Participants in the FAO/IAEA Co-ordinated Research Programme on"Evaluation of semi-dwarf cereal mutants for cross breeding" met 2 - 6April at CIMMYT (Mexico) to review results obtained during the last twoyears. Good progress has been made in identifying new sources ofdwarfing genes and in evaluating such genes in various geneticbackgrounds or environmental conditions. For the start of work under anewly established co-ordinated research programme on "Improvement ofroot and tuber crops and similar vegetatively propagated crop plants intropical countries by induced mutations", the first research

. 33/30

co-ordination meeting was held 17 - 21 December at Pattya (Thailand).In-vitro cultures are going to play a major role in this new programme.

Under the frame of the IAEA Technical Co-operation Programme,projects have been serviced in Brazil, Ghana, Indonesia, Malaysia,Mongolia, Panama, Peru, Venezuela, Yugoslavia, Zambia.

In the meantime, final preparations for the InternationalSymposium on Nuclear Techniques and In-Vitro Culture for PlantImprovement, to be held in Vienna, 19 - 23 August 1985 have begun.Unfortunately, due to lack of funds, the in-vitro culture trainingcourse originally planned in conjunction with the symposium had to becancelled.

Non-nodulating and non-fixing mutants of pea

Pea mutants unable to fix atmospheric nitrogen in symbiosis withrhizobium are valuable for characterization of plant genes involved innitrogen fixation. They would also be useful in physiologicalresearch, although probably not in plant breeding.

Induction of non-nodulating, non-fixing and nitrate resistantnodulation mutants is now investigated in several laboratories [1-31.

'Finale1, a low white flowered, strongly determinate cultivar withlarge round green seeds was chosen. It is grown in many Europeancountries and known for stable yields. The major disadvantage of'Finale' is a rather low seed production.

Lots of 1.5 kg (about 4500 seeds) were (a) soaked in 0.1% EMSovernight or (b) presoaked in water overnight and treated with 0.5% EMSfor one hour or (c) presoaked in water overnight and treated with 0.5%EMS for two hours. The wet seeds were treated with captan fungicideand sown in the field. One pod per plant was harvested. The Mjseeds were sown in sand in plastic trays and inoculated with a mixtureof rhizobium strains. About 27000 M2 plants were scored during thewinter in the greenhouse at about 18°C with supplementary fluorescentlight and fertilized with a PK fertilizer. Chlorophyll mutants werecounted and discarded.

M- plants with nitrogen deficiency symptoms, yellowing from theroot upwards, were taken out of the sand and scored for white, green orno nodules. Tentative mutants were planted in soil and the progenyretested.

Until now three non-nodulating mutants have been confirmed. Amutant with large red nodules, but poor growth and low nitrogen

fixation is being further investigated. Non-confirmed mutants havebeen "slow" chlorophyll mutants or plants with nodules destroyed byPvthium species.

Utilization of a yellow seeded Trombay mustard mutants in cross breedinR

Indian or oriental mustard (Brassica .iuncea (Linn.) Czern & Coss.)available in the germplasm collection in India until late 1960s werewith black or brown seed coats. A yellow seed coat mutant TH-1(Trombay Hustard-1) was produced at this Research Centre by Nayar [1].since then attempts have been made to evolve improved varieties ofmustard with yellow seed coat [2,3]. TM-4, TM-9 and TM-12 with yellowseed coats were developed after hybridizing TM-1 with Varuna, the blackseeded national check cultivar. At Trombay, they were earlier inflowering and produced higher seed yield than TH-1 and Varuna. Theiroverall crop duraton was around 100 days, compared to 116 days forVaruna. The oil content in the yellow seed coat cultivars was 36%compared to 34% in Varuna. Further, it was reported that the feedingvalue of seed meal after oil extraction is superior for the yellowseeded coat and less crude fibre [4]. TM-4, TM-9 and TM-12 were testedfor their yield potential in the All India Co-ordinated ResearchProject on Oilseeds (AIC0RP0) for five years. They performed better inthe eastern parts of the country and in Raj asthan State, because oftheir short duration.

Earlier, Brassica campestris var. yellow sarson was widelycultivated in India. Gradually the polyploid species B. iuncea withblack or brown seeds is replacing yellow sarson, but consumers preferyellow seeds and are willing to pay a higher price. Therefore, one ofthe priority objectives in breeding programmes of AICORPO is to developimproved cultivars of mustard with yellow seed coat. According to the1983 AICORPO Rapeseed and Mustard Report, breeders are using the yellowseeded mutant TM-1 and its derivatives extensively in crossingprogrammes, e.g. at GB Pant University of Agriculture and Technology,Pant Nagar; Agricultural Research Station, Durgapura, and HaryanaAgricultural University, Hissar. F2 seeds of some crosses are madeavailable upon request to other breeding stations by Dr. P.R. Kumar,Haryana Agricultural University, Hisar, Haryana State, India.

Comparative studies on callose formation in powdery mildew compatibleand incompatible barley

Callose formation in barley mutants, lines and varieties withdifferent genes for resistance to powdery mildew in seven differentloci was compared. Only barley with resistance genes in the ml-o locusshowed so early a callose -formation passing off at such a high ratethat it prevented fungal penetration. Ml-(La) resistant varieties andnear-isogenic lines in 'Manchuria' with resistance genes in five otherloci showed only a tendency to a larger callose formation than theirsusceptible counterparts after inoculation with avirulent as well asvirulent powdery mildew.

The callose formation in ml-o resistant barley was independent ofthe powdery mildew culture applied. This supports the hypothesis setforth as to why the ml-o mutants are resistant against all knowncultures or races of barley powdery mildew, and why this resistance maybe more durable than other powdery mildew resistances. Further, thisis the first case where the effect of callose refers to the action of aspecific gene.

Six susceptible Japanese varieties formed very large appositionsbut they were initiated as late as in other susceptible varieties, andtheir colour was paler than in other barleys.

Nine Hordeum species fell in one group with small appositions andanother with appositions of the most common size in barley. Wheatreacts strongly with deep coloured appositions, rye with haloes with asomewhat diffuse margin, and oats with large, central spots (papillae)nearly without any halo.

Screening for spontaneous virulent mutants of barley powdery mildew

Seedlings of four barley lines with powdery mildew resistancegenes Ml-al, Ml-a6. Ml-al2. or Ml-K were inoculated with an avirulentpowdery mildew culture. In total 50 million viable conidia werescreened for the occurrence of spontaneous virulent mutants during 30cycles of screening. Forty-three putative virulent mutants wereselected, multiplied and tested. They comprised five differentgenotypes according to their virulence spectrum on about 25 differenthosts. Based on virulence spectra, three of the types were rejected asnot being of mutational origin, and the verification of the remainingtwo types was not consistent with the expectations from a gene-for-geneinteraction. Assuming that none of the five genotypes were ofmutational origin, the spontaneous mutation frequency from avirulenceto virulence in barley powdery mildew is therefore below 2 x 10"~".

"Co2" a new high yielding mutant variety of groundnut

Groundnut is an important oilseed crop in India. In Tamil Nadu itis cultivated on nearly 1 million hectares, 13% of the area undergroundnut in India. Limited variability in the germplasm imposes arestriction on improvements that could be obtained throughrecombination. Investigations commenced in 1973 to develop newgenotypes through mutagenesis.

Soaked seeds of Pol-1 groundnut were treated with ethyl methanesulphonate (EMS) at 0.04, 0.06, 0.08, 0.1 and 0.2 percent. Thepopulations from these treatments were carried forward to M2 andM3generations. Selections were made in M3 for number of pods perplant, shelling percentage and other economic characters.

lines were further observed for uniformity in M4 and M5 generations andseveral of them were tested in replicated yield trials from 1979onwards. Mutant line No. 3, derived from 0.2% EMS treatment was foundto be particularly promising and therefore was further tested for itsyield potential under rainfed as well as irrigated conditions alongwith standard varieties Col and TMV12 presently under cultivation.Mutant 3 exceeded these varieties considerably in yield at all testsites (Table).

Based on the good performance, groundnut Mutant 3 was released asvariety "Co2" for general cultivation in Tamil Nadu.

Induced mutations in roses

A number of new rose varieties have been produced at IARI, NewDelhi (Kaicker and Swarup 1971, 1978); (Swarup, Kaicker and Gill 1971)and (Kaicker 1982, 1983) through the use of both physical and chemicalmutagens. IAEA varieties from induced mutants that have beencommercialized and are very popular with rose growers are Abhisarika,Madhosh, Pusa Christina and Striped Christian Dior (IARI, 1971).

Recently investigations were carried out at IARI, New Delhi on theeffects of gamma irradiation on sprouting, survival, growth, floweringbehaviour and induction of somatic mutations in hybrid tea rosecultivars, Folklore (Kordes 1978) and Doris Tystermano (Wisbech 1975).

The former is a great exhibition and cut variety of ravishing 25 -30 petals beauty with long pointed buds which unfurl to large perfectlyformed blooms of a rich salmon orange colour with a light yellowreverse. The latter is perfectly shaped with tangerine and gold colourdeepening to orange at the petal edges.

10 to 15 cm long scions having 4-6 healthy buds of about one yearold growth were taken from October pruning. They were irradiated in a2000 curie 60Co source, at the Division of Genetics, I.A.R.I. (doserate 2.0 kR per minute, dose 2.5 to 5 kR). The irradiated bud was

afterwards removed from the scion wood and propagated by T-budding onRosa indica - odorata rootstock.

The sprouting of buds decreased with increase of gamma irradiationdose. After one year of growth in treated plants show still a dwarfingeffect of the treatment.

Interesting mutants obtained are the following:

Orange Folklore: A highly attractive mutant which occured from 2.5 kRtreatment first as a periclinal chimera; It has more than 35 petals ofyellow group 13-B (R.H.S. colour chart). Outer petals are with yelloworange colour (group 15-A). Older petals of the first whorl areshaded orange (29-C). It was isolated as solid mutant in MV2.

Orange Folklore with tipped pink petals: This highly attractive mutant(from 2.5 kR) has an increased petal number (50-55) and yellow orangecolour of the petals with blush pink petal edges. It was obtained as apericlinal chimera. The mutants of Folklore differ in Florachrome Bcontent.

Doris Tvstermann with less number of petals: This mutant (from 4 kradtreatment) had 18-20 petals instead of 25-30 petals with tangerinecolour darkening to orange at petal edges as in the control.

Resistance of Indonesian mutant lines to the brown planthopperNilaparvata lugens

We tested seven mutant rice lines, derived from BPH susceptiblePelita I/I, for resistance to BPH at IRRI. The lines came from theNational Atomic Energy Agency in Jakarta, Indonesia. They were Atomita1, 627/10-3/PsJ, Atomita 2 and 627/4-E/PsJ, derived from Pelita I/Iirradiated with 0.2 kGy of gamma rays; and A227/2/PsJ, A227/3/PsJ andA227/5/PsJ derived from an early maturing mutant of Pelita I/Iirradiated with 0.1 kGy of gamma rays. We conducted two tests withfive replications to measure their level of resistance to BPH: seedboxscreening for plant damage, and population growth.

In the seedboi screening test, seeds of entries were planted inseedboxes. Seven days after sowing, they were infected with eightsecond and third-instar BPH nymphs/seedling. Plant damage was ratedwhen the susceptible check died. In the second test, 30 days old testplants were infested with 5 pairs (male and female) of 2 to 3 days oldadult BPH and enclosed with mylar film cages. When their progenyreached adulthood on susceptible TNI plants, the insects in all thecages were counted.

The Indonesian mutant lines were resistant to moderately resistantto biotype 1 and biotype 3, but susceptible to biotype 2. Similarseedbox screening tests showed the mutant lines were moderatelyresistant to green leafhopper and whitebacked planthopper, as comparedwith susceptible TNI.

Atomita 2 has been released for commercial cultivation inIndonesia. In addition to its resistance to BPH biotype 1 and biotype3, it has high yield potential, good eating quality, and salinitytolerance.

New Publications

Handbook of Plant Cell CultureEvans, D.E., Sharp, W.R., Ammirato, P.V., Yamada, Y. (Eds.):Vol.1 Techniques for Propagation and BreedingVol.2 Crop Species

Macmillan Publishing Co. New York 1983/84.

In spite of numerous books and proceedings from internationalsymposia summarizing the status and progress in the field of planttissue and cell cultures, a complete survey of problems, methods andapplications of this fast developing scientific discipline has not yetbeen available. This gap will be plugged by Macmillan PublishingCompany, New York publishing the Handbook of Plant Cell Culture inseveral volumes dealing with basic and specialized techniques ofin-vitro plant cell cultures and their application in plantbiotechnology, breeding and agriculture. The first volume entitled"Techniques for Propagation and breeding" appeared in 1983, the secondvolume "Crop Species" in 1984.

Volume 1 contains basic information concerning fundamentaltechniques and problems of plant cell cultures, e.g. organogenesis,embryogenesis, cultivation of protoplasts, somatic hybridization,in-vitro selection, meristem cultures and haploid production, but alsodeals with specifics of plant cell culture, genetics and physiology,including molecular techniques and biochemical mechanisms. Volume 1also reviews cell culture application for chemical compound production,plant breeding, nitrogen fixation, and germplasm preservation. Aninternational team of authors gives a critical account of literatureand practical guidance for the application of in-vitro techniques.Numerous references supplement the summary tables so that the readerobtains quick lucid information but can also follow up the details.Owing to precise methodical protocols the book becomes essentially amanual for planning and conducting the initial experiments by studentsand by research workers who are beginners in the particular field.Experienced workers, on the other hand, will find here auniquemethodical survey covering the relevant aspects of plant cellcultures. Authors also attempt to outline further developments andpossible future applications.

Volume 2 deals with crop plants and their genetic improvement byusing in-vitro culture techniques. A general overview of world cropproduction, food supply and trade attempts to set the stage for plantcell cuture techniques as a future means for reducing hunger andmalnutrition, but another overview makes clear that cell culturetechniques have to be carefully integrated into sound plant breedingprogrammes to have an impact upon crop production. Specific chaptersof this volume deal with maize, oat, wheat, bean, clover, asparagus,celery, cassava, sweet potato, banana, papaya, apple, grape, conifers,date palm, rubber tree, sugarcane and tobacco. Volume 3 is expected tocover other crops.
