Abstract

Seed yield performance and effect on seed yield of morphological traits such as seeds/panicle, seed weight, seeds/branch, branches/2nd node, branches/panicle, fertile tillers/plant and panicle length were evaluated in 13 cultivars of smooth bromegrass in a spaced-plant nursery. Wide variation was observed between and within cultivars for seed yield and traits. Highly significant correlation coefficients were found among traits and seed yield. Path analysis showed that specifically seeds/panicle and seed weight had strong direct effect on seed yield. It was concluded that seeds/panicle and seed weight were primary selection criteria for seed yield in smooth bromegrass.
