To develop high protein lines, several crosses were made betweenCajanus as a source of acceptable seed size andAtylosia as a source of high protein. In the present study, 1974 single F7 plants from these intergeneric crosses were examined. Correlation coefficients among these crosses between seed size and seed protein content ranged from −0.30, (P<0.01) to +0.28 (P<0.01). Two crosses had significant negative correlations and one showed a significant positive correlation while in the remaining two no significant association was detected. Based on all the selections there was a highly significant negative correlation (−0.13,P<0.01) between seed size and protein content. However, the extent of variation that could be attributed to this association was small. Observations indicated that in pigeonpea, unlike other legume and cereal crops, simultaneous improvement can be made for seed size and protein. Some high protein lines (HPL 2, HPL 7, HPL 40, and HPL 51) have been identified. Protein content of these lines ranged between 27.0 and 29.0% and 100-grain weight between 10.0 and 12.1 g.
