ABSTRACT
In the present investigation the genotypic correlation coefficients were slightly higher than phenotypic correlation coefficients. The analysis of variance revealed highly significant differences among the genotypes for all the twelve characters under studied, indicated the wide range of genetic variability in the existing material. The characters viz., harvest index, number of pods per plant, 100-seed weight, pod length, number of secondary branches per plant, number of primary branches per plant, number of seeds per pod, plant height, days to maturity and days to 50 per cent flowering showed significant positive correlation with seed yield per plant. In the association among component characters, days to 50 per cent flowering significantly and positively correlated with days to maturity, plant height, 100-seed weight whereas, protein content was negatively significant. Days to maturity correlated with plant height, 100-seed weight and harvest index. Path analysis revealed that harvest index, number of seeds per pod, pod length, days to maturity and number of secondary branches per plant recorded the maximum and positive direct effects on seed yield per plant and their association with seed yield per plant were also highly significant and positive.
Key words: Correlation, Path Analysis, Variability, French Bean.
