Genetic analysis of beta-glucan and protein content was conducted using an eight parent (ICNBF-582, ICB-102607, ICNBF93-328, SB91925, ICNBF8-613, BBSC congana, Petuina2 & ICNBF93-369) of hulless barley (Hordeum vulgare L.) in diallel fashion. Generation mean analysis was carried out on P1, P2, F1, F2, BC1 and BC2 of crosses ICNBF93-369× ICNBF-582 and SB91925× ICB-102607, to complement the genetic information from the diallel analysis. Data showed that although additive and dominance variance were important, these traits was more influenced by additive effects. High values of narrow sense heritability for both traits also confirmed it. Generation mean and variance analysis indicated that additive effects were important for protein content in cross SB91925× ICB-102607 and beta-glucan content in both crosses. These analyses indicated over-dominance towards the better parent for protein content in cross ICNBF93-369× ICNBF-582.
