Impact of Bi-Parental Mating on Character Association in Barley (Hordeum vulgare L.)

Abstract

Correlation between grain yield and contributing characters in 100 biparental progenies (BIPs) developed from a barley cross RD-2035 x RD-2552 and corresponding F3 progenies were compared. The correlation coefficients in BIPs were found generally of higher magnitude than F3 progenies. Even, non-significant negative association in F3 between grain yield per plant and harvest index converted into significant and positive in BIP progenies. Higher degree of positive and significant correlation was observed in tillers per plant, spikelets per spike and grain per spike with grain yield per plant in BIPs as well as F3 population.
