| Abstract: | Summary Six interspecific/intergeneric F2 populations involving two cultivars of C. cajan and five Atylosia species were scored for segregation patterns for pod length and ovule number. It was observed that for both characters the F2 means and the ranges were correspondingly lower than the midparent values and the spread of the two parents. However, the intrageneric cross of A. lineata and A. scarabaeoides showed transgressive segregation for pod length and the F2 mean and range were correspondingly larger than the midparent value and spread of the two parents, suggesting the usefulness of combining ability test for choice of suitable parents. |
