Online published on 21 February, 2022. Abstract The present investigations were carried out to study the genetic diversity analysis among 56 diverse genotypes of chickpea (Cicer arietinum L) for twelve quantitative characters by using Mahalanobis D2 statistics during rabi season 2018-19 at Zonal Agricultural Research Station, Ganeshkhind, Pune, Maharashtra. The 56 genotypes of chickpea were grouped into eight non-overlapping clusters. Cluster I with 24 genotypes emerged as the largest cluster followed by Cluster II with 14, Cluster III with 12 and Cluster IV with 2 genotypes. The Cluster V, VI, VII and VIII were monogenotypic containing only one genotype. It was observed that there was a wide diversity among the genotypes with D2 values ranging from 34.11 to 989.73. The highest D2 value was observed between the Cluster VI and Cluster VIII having genotypes Phule-G-15109 and Phule-G-0739. This suggested that these genotypes had large source of variation and were useful for future breeding programmes. Top Keywords Chickpea, Genetic diversity, Cluster analysis, Divergence. Top |
