Abstract:

Heterosis and genetic variance component studies on 36 wheat crosses and 14 parentsrevealed that:1.Yield per plant,kernels per spike and kernel weight of F_1 hybrids showed a markedheterosis over mid-parental values by 20-30%.Plant height and date of heading ranked next,which averaged about 10% in magnitude,being negative in direction for heading date.Fertilespikelets per head manifested only a slight degree of heterosis.F_(1-)MP s for these characterswere highly significant as shown by t-tests.However,head...
