Abstract
Correlation and Path coefficient analysis study were conducted using two hundred and twelve genotypes to screening of Yellow Mosaic Virus Disease. An experimental field were raised with susceptible check in YMV hotspot region of Tamil Nadu. Data were recorded for eleven biometrical traits. Plant height, number of branches per plant, number of clusters per plant, number of pods per cluster, number of pods per plant, pod length, number of seeds per pod and hundred seed weight had significantly positive association with single plant seed yield. Its indicating the trait single plant seed yield was highly correlated with these independent variables. Days to fifty percent flowering and yellow mosaic virus disease score had significant and negative association with single plant seed yield. Similar outcome were reported by earlier study. In genotypical path coefficient matrix number of pods per plant and number of seeds per pod exhibits maximum low positive direct and indirect effects towards single plant seed yield and most of the component traits. in phenotypical path coefficient matrix, number of pods per plant alone shown low and negligible positive direct and indirect effect towards single plant seed yield and most of its component traits; plant height and days to fifty percent flowering exhibits low negative indirect effect.
