The analysis of 9 × 9 half diallel F1's generation alongwith parents were grown in two environments. Genetic analysis for protein and ascorbic acid contents showed that both additive as well as non-additive genetic variance were highly significant for these two characters. Prevalence of dominant genes and over dominance was observed. Heritability values were medium in E2 but in E1 protein content had low heritabiilty. Delayed plantings showed reduction in both protein and ascorbic acid contents, however, ascorbic acid was more sensitive than protein content. The parents Bonneville and GC195 were good general combiners for both these traits. In gereral there was fairly good agreement between per se performance and the gca of the parents for both the characters. The cross combination GC141 × Bonnevelle, Bonneville × Multifreezer, GC141 × GC195 for protein cantents and Early Giant × GC195 for ascorbic acid contents were identified as having positive sea effects. The possibilities of identifying desirable segregants are discussed.
