Inter-relationships between yield and its component traits in long duration hybrids in pigeonpea

摘要

Eighteen experimental long duration pigeonpea hybrids were studied for ascertaining the inter-relationships between yield and its components. Number of primary and secondary branches, Harvest index, dry matter at maturity and pods per plant exhibitedpositive correlations with yield. The main contribution of direct effects towards yield was observed for Harvest index, dry matter at maturity, number of primary branches and pods per plan negative d irect effects were observed for traits like secondarybranches, 100-seed weight, seed per pods and plant height. The results indicate a need for proper balance between biomass and harvest index by way of reduction in plant height and number of secondary branches.
