ABSTRACT : Male-sterility in chilli was documented for the first time in the 1950’s. Since then, considerableknowledge has been accumulated on the nature of the trait, the means of its identification, induction,inheritance of both genetic and cytoplasmic genetic male-sterility, maintenance of inbreds, and their potentialfor breeding hybrid cultivars. Heterosis for various economic traits like; maturity, fruit weight, size, number andtotal yield have been utilized. Today, several internationally known seed companies and research institute usethe genetic mechanism [msms] on a large scale for producing hybrids of sweet pepper, whereas thecytoplasmic genetic sterility [(S) Rf rf] is used mainly for breeding pungent hybrids. The possibilities ofexploitation of male sterility for crop improvement as well as production of F1 hybrids have been reviewed anddiscussed in the present paper. Biochemical as well as biotechnological aspects of this phenomenon has alsobeen vividly reviewed.

ABSTRACT : Studies were conducted to optimize planting distance for frond production in Boston fern[Nephrolepis exaltata (L.) Schott]. The suckers were planted at a spacing of 30 x 30 cm, 30 x 45 cm, 45 x 45cm, 45 x 60 cm and 60 x 60 cm, in the month of March, 2012 under net house conditions which provided 50 per cent shading. Planting density had significant effect on plant spread, frond length, mean lamina length and leafarea. Increase in planting density (30 x 30 cm) led to increase in frond production per unit area but with regardto the production per plant, it was at par in all the spacings where row to row distance was 45 cm i.e. 45 x 30cm, 45 x 45 cm and 45 x 60 cm. Number of fronds per plant increased as the plants were widely spaced,highest being recorded at 60 x 60 cm. The fronds produced from wider spaced plants were of superior qualityin terms of length and strength of the stem. Quality parameters, viz. length of longest frond as well as freshand dry weights of fronds was observed to be higher with closer spacing. Frond production per plot and yieldper hectare exhibited significant increase with decreasing plant spacing. Planting density did not affectlongevity of the fronds. Considering the yield of fronds per hectare, cost of production and net return, 30 x 45cm spacing is recommended for the cultivation of Boston fern.

ABSTRACT: The study was conducted to assess the effect of antioxidant on post-harvest quality of pear fruitscv. Punjab Beauty with treatments of DPA (500, 1000 and 1500 ppm) during storage. After treatment the fruitswere packed in corrugated fibre board (CFB) cartons and then stored in cold storage at 1-3oC temperature with 90-95% RH for 45, 60 and 75 days. The observations revealed that pear fruits treated with higherconcentration of DPA i.e. 1500 ppm recorded lowest physiological loss in weight, spoilage losses, corebrowning and fruit colour degradation. Same concentration of diphenylamine (DPA) maintained higher fruitfirmness, TSS, reducing sugars and acidity throughout storage period. With the prolongation of storage periodphysiological loss in weight (PLW%), spoilage percentage, core browning, fruit colour degradation, totalsoluble solids and reducing sugars followed an upward and acidity showed downward trend. Diphenylamine

treated fruits could be cold stored for 75 days in CFB cartons with lowest weight loss, spoilage and better fruitquality. Fruits under control showed higher spoilage and shriveling due to loss of weight and firmness.

ABSTRACT : Rhizome rot of ginger, caused by Pythium aphanidermatum (Edson) Fitz, is a major constraint

for the production of healthy rhizome, sometimes causing total failure of crop. Chemical control of this

pathogen is not economical and non-ecofriendly. Thus, the treatment with bio-control agent (Trichoderma

viride) may offer practical and economical alternative for eco-friendly management of this disease. The lowest

disease incidence (18.00 %) was recorded in T5 - Rhizome treated with Trichoderma viride @ 10g/l of water +

Three foliar sprays of Trichoderma viride @ 4 kg/ha followed by T4-Rhizome treated with Trichoderma viride @

10g/l of water + Two foliar sprays of Trichoderma viride @ 4 kg/ha with disease incidence of 24.33 %. The

highest disease incidence (86.33%) was recorded in T6 (control) which was raised without any rhizome

treatment and foliar sprays.

ABSTRACT: At present, about 61 per cent area of fruit crops in the Punjab state is occupied by Kinnowmandarin which is mainly propagated on rough lemon rootstock. Polyembryony, sterility, poor viability ofhybrid seeds, unknown mode of inheritance and long juvenility present major problems in citrusimprovement through conventional breeding programme. Tissue culture and biotechnological methodsprovide fast improvement to a particular crop and their success rests upon the reproducible and efficientregeneration protocols. The experiment carried out on effect of proline on tissue culture aspects of roughlemon (Citrus jambhiri) revealed that proline might have reduced the effect of NAA and can replace ABAin direct regeneration of citrus rootstock rough lemon.

Significantly wide variation was recorded in all floral traits.Results revealed that maximum number of flowers/plant (81.51) and flowering duration (43.14 days) wererecorded in Anmol. Maximum plant height (47.25 cm) and flower diameter (5.03 cm) were recorded in GardenBeauty. However, maximum average weight of flower (2.59 g) and flower yield/plant (131.43 g) were recordedin Autumn Joy. The genotype Winter Queen recorded maximum number of sprays/plant (6.89). On the basis of three years observations, genotypes Winter Queen, Garden Beauty and Autumn Joy found promising forgarden display.
