Correlation and Path Analysis of Grain Yield and Physiological Attributes in Greengram (Vigna radiata (L.) Wilczek)

摘要

Twenty one F_4 progenies derived from a 7 x 7 diallel cross of greengram were evaluated to assess the role of physiological parameters in determining the grain yield. Correlation analysis revealed strong positive association of biomass at harvest, NARand RGR between 35-50 DAS, CGR between 35-50 DAS and 50 DAS, maturity and HI with grain yield and also among themselves. Path coefficient analysis suggested that NAR between 20-35 DAS and 50 DAS and maturity showed high direct effects on grain yield which could be considered as a selection criteria for improving seed yield in greengram.
