ABSTRACT

​

The present investigation was carried out at Agriculture Research Sub-station, Sumerpur. In the study six popular cultivars of chickpea were under consideration. The correlation study elucidated that seed yield has positive and highly significant correlation with number of primary branches per plant (0.96) and number of pods per plant (0.97) while none of the characters showed negative correlation with seed yield. Similarly, days to 50 % flowering showed positive and significant correlation with days to maturity (0.86) and plant height (0.82). The diversity among the varieties were studied using K-means and ward’s method. Through both the methods it was observed that CSJ-515, GNG-2144 and GNG-1958 were clustered into one cluster (cluster I), RSG-974 and RSG-959 were clustered into another cluster (cluster-III) and GNG-2171 remained alone (cluster-II). This showed that both the clustering methods are in agreement with each other. In terms of yield cultivar CSJ-515 reported highest mean seed yield per plot (2.65) followed by GNG-2144 (2.41).
