Abstract:

The experimental material was consisting of 108 RILs derived from a cross of VRM (Gg) 1 × TNAU RED. The experiment was laid out in Randomised Complete Block Design with 3 replications. The observations were recorded on five randomly taken plants for six quantitative traits viz. days to fifty percent flowering (DFFW), plant height (PH), number of clusters per plant (NCP), number of pods per plant (NPP), hundred seed weight (HSW) and grain yield (GY) to estimate the correlation and path analysis. The correlation revealed that the grain yield had positive and significant association with number of pods per plant (0.77) and number of clusters per plant (0.48). Path analysis showed that the moderate negative direct effect was exhibited by number of clusters per plant (-0.218) followed by the low positive direct effect by hundred seed weight (0.132) and days to fifty percent flowering (0.125). Hence, combined results of correlation coefficient and path analysis emphasis that number of pods per plant are major component traits for the improvement of grain yield.
