The inflorescence weight as selection criteria for increasing seed production in alfalfa
This paper summarize the works realized in variability and genetic control, and also environmental effects on the alfalfa seed production, and it propose a selection criterion, and a breeding scheme for improving seed production in this forage. The seed production and its components showed a large genetic variation among and within-varieties. The larger narrow-sense heritability were found for seed production per plant (0.52), seed weight per inflorescence (0.56) and seed number per pod (0.56), while the additive variance contributed most of the genetic variance of these components. The genotype x environment interaction for seed production was found. In contrast, the seed weight per inflorescence showed higher stability to environment and the correlation between this trait and seed production was high at the genetic level (0.91, P
