TITLE: Spring Wheat

PROJECT: Small Grains Investigations MS 756

YEAR: 1982

PERSONNEL: Leader - Vern R. StewartTechnician - Todd K. KeenerCooperators - Wheat Research Committee MAES

OBJECTIVES: 1. To determine the adaptability of new and introducedspring wheat varieties and selections.

2. To aid in basic genetic research programs in spring wheat.

EXPERIMENTS FOR 1982:

1. Private Variety Nursery2. Western Regional Spring Wheat Nursery

RESULTS AND DISCUSSION:

Good yields were recorded from the Private Variety Nursery withfive varieties yielding significantly higher than the check variety, Newana.Seven other varieties tested produced above the 100 bu/a mark. Thirteen vari-eties yielded significantly less than the check variety, eleven of those dueto severe lodging problems. Test weights were above normal throughout thestudy and only three varied significantly from the check variety. Headingdates were about equal to last year with those dates and heights varying be-cause of variety differences. The majority of the taller varieties (over 39.5inches) were susceptible to lodging. All varieties were reported to have somelevel of tan spot (Pyrenophora trichostonia) with seven varieties having sig-nificantly less infection than Newana (15%).

Western Regional Spring Wheat Nursery - Excellent yields wereharvested from the Western Regional Spring Wheat Nursery. Of the seven varie-ties producing yields significantly higher than the check (Owens) six werewhite. The Washington Potam 7/WA6021 K790 crosses were all significantly highyielders in this study. Almost three-fourths of this nursery yielded above103 bu/a.

Test weights were slightly above normal (last 3 years average)with the average being 55.86 Ibs/bu.

Tan spot was recorded in all varieties, but did not get above a15% infection level as was reported in WA6826 and UT541777.

Lodging was most prevalent in those varieites which produced sig-nificantly less than the check. Two Idaho varieties (ID246 and ID172) weresusceptible to lodging, yet still yielded satisfactorily.
