Abstract
Four lines of pigeonpea (Cajanus cajan (L.) Millsp.) ware selected for variability in protein content and were used as parents in crosses. The F2 mean protein contents were generally between the parents, but slightly closer to the low-protein parent. Reciprocal differences in protein of F1 seeds and its absence in F2 seeds showed that the maternal genotypes controlled protein content. The broad sense heritability estimates varied from 34 to 62 per cent in different crosses. These low and variable values indicate high environmental-influence on protein content and relatively low additive genetic variance. A minimum of 3 or 4 genes control protein content. Low protein was partially dominant over high protein. Grain yield and protein content were negatively correlated in F2 plants from crosses between low and high protein lines. Grain yield and protein yield were highly correlated. It is suggested that for total protein production per unit area efforts should be directed towards increased seed yield while maintaining per cent protein near average levels rather than by selecting for high protein in the grains alone.
