Abstract

Twenty two CMS-based pigeonpea [Cajanus cajan (L.) Millsp.] hybrids were evaluated to study the nature and magnitude \nof relationship of important agronomic traits with seed yield along with their direct and indirect effects in determining yield. \nThe results showed that days to flower, number of secondary branches, pods/plant, seeds/pod, and seed size in hybrids had \ndirect positive effects in determining yield. Among hybrids only the number of pods/plant was positively associated with \nseed yield.
