Determining relationships among yield and some yield components using path coefficient analysis in chickpea (Cicer arietinum L.)

This research was conducted to determine the relationships among yield and some yield components of chickepea by using correlation and path coefficient analysis. The experiment was carried out in the experimental field Kharke Sanandaj in 2006. In this study, 36 chickpea cultivars were used. The experimental design was Triple Lattice Design. Positive and significant relationships were found among seed yield and number of pods per plant, number of seeds per pod, biological yield and harvest index. Negative and non significant relationships were determined among seed yield and 100-seed weight, number of primary branches, days to flowering, days to first pod formation and days to maturity. According to path coefficient analysis, there were strong direct effects of the harvest index (0.901), biological yield (0.194) and number of pods per plant (0.048) on the seed yield.
