Correlation and Path Analysis Studies in Chickpea (Cicer arientinum L.) Genotypes under Foothill Condition of Nagaland

The analysis of variance revealed significant differences among genotypes for all the characters studied, indicating high degree of variability in the material. The magnitude of genotypic correlation tended to be higher than phenotypic correlation for most of the characters. This suggested a strong genetic association between these traits. For the grain yield significant positive correlation was observed between 100 seed weight and harvest index indicating relative utility of these traits for selection. The path analysis revealed that 100 seed weight contributed maximum positive direct effect on yield indicating a true relationship among the traits. The present study suggested that while selection emphasis should be given for 100 seed weight for improvement in seed yield.
