Abstract
The present investigation consists of 35 genotypes of Chickpea including one check, which were grown in the Field Experimentation Centre of the Department of Genetics and Plant breeding, SHUATS, Prayagraj during Rabi 2019 following RBD with three replications. The data were recorded on 13 characters to study the amount of genetic variability, heritability, Genetic Advance, Genetic advance as percent mean in the chickpea genotypes. Based on the mean performance genotype ICC-4968 followed IC-244253 and Phule- 4-5 were identified as best genotypes for seed yield per plant. High significant variation was obtained for all characters studies. High heritability estimates were observed for Number of primary branches, Seed yield, harvest index followed by number of pods per plant, number of secondary branches, biological yield, number of seeds per plant, number of seeds per pod, 100 seed weight, days to 50% flowering, days to maturity, days to 50% pod setting, and plant height. High values for heritability indicates that it may be due to higher contribution of genotypic components. High genetic advance as percent of mean was recorded high for seed yield, harvest index, biological yield, number of pods per plant, number of primary branches, number of seeds per plant, number of secondary branches, number of seeds per pod, hundred seed weight, plant height, days to 50% flowering, days to 50% pod setting, days to maturity. Metroglyph analysis shows, analysis of variance indicated that significant variations among the 35 lines for thirteen characters. The scatter diagram revealed that five complexes could be distinguished on the basis of Morphological variation. Maximum number of genotypes falls in cluster I and II (11) followed by cluster III (6), cluster IV (4) and cluster V (3). The germplasm lines, IPC-97-29, ILC-0, ILC-3279, IPC-11-85, IC-244263 recorded high index score and fell into different clusters can be crossed to have maximum variability of good combination of characters. Thus, the use of these genotypes in future breeding programme is suggested. Moderate to high level of genetic diversity was obtained using D2 statistics indicates that, this method can be used successfully in the genetic diversity analysis of chickpea. Grouping of genotypes into various clusters D2 statistics is effectively done by Torcher’s method. The 35 genotypes were grouped into five distinct clusters named as cluster I to Cluster V. These clusters comprised 31,1,1,1 and 1 number of germplasm lines. Maximum number of genotypes falls in cluster I (31). More the cluster, more will the genetic diversity and thus genotypes which are included in large distantly clusters are more significant to the further crossing programme. Clusters having small genetic distance are genetically similar from each other, and thus cannot use for crossing because of lacking the diversity.
