Genetic Divergence in Chickpea (Cicer arietinum L.)

Abstract

Genetic diversity of 27 chickpea genotypes was studied through Mahalanobis D2 and Principal Component analysis. The genotypes under study fall into five clusters. The cluster II contained the highest number of genotypes (11) and Cluster I contained the lowest. Cluster I produced the highest mean value for number of pods per plant. The inter cluster distances were much higher than the intra cluster distances. Cluster V exhibited the highest intra cluster distance while the lowest distance was observed in cluster I. The highest inter cluster distance was observed between cluster I and II while the lowest was between cluster III and V. Considering all the characters, it was suggested that the genotypes BD6549, BD6603, and BD6548 could used as parents for future breeding programs to develop high yielding varieties of chickpea.

Genetic Diversity and Geographic Relationship Studies in Chickpea (Cicer arietinum L.) Germplasm

“…Among the nine characters studied the most important characters contributing to the divergence were seed index (69.22%) followed by number of days to maturity (8.94%) and Biological yield per plant(8.01%), plant height (5.23%), days to 50% flowering (3.60%) and harvest index (2.44%). These results are in agreement to the earlier findings by Rajkumar et al, 2015, Sachinet al, 2014, Syed et al, 2012and Zakiaet al, 2012 Genotypes belonging to clusters separated by high genetic distance may be used in hybridization program to obtain a wide spectrum of variation among the segregates in the present study and similar suggestion had been made by Sachin et al, (2014), Syed et al, (2012) and Zakia et al, (2012). The genotypes included in the diverse clusters namely II, III, IV and VII hold good promise as parents for obtaining potential hybrids and thereby creating greater variability of these characters to improve the yield.…”

“…It indicates that most likely the heritability is due to additive gene effects and selection for these traits may be rewarding. Similar findings have been reported by Sachin et al, (2014), Syed et al, (2012) and Zakia et al, (2012) in chickpea.…”

Determination of genetic divergence in pointed gourd by principal component and non-hierarchical euclidean cluster analysis

“…This is in agreement with Syed et al, (2012) who reported that clustering of chickpea genotypes did not follow geographical distribution. The genotypes with their respective places of origin and clusters have been presented in (Table 2).…”

Genetic divergence analysis in chickpea germplasm

“…Selecting parents from the maximum et al, 2002;Kumar et al,2017). Similar result has been reported by Dwevedi and Lal, (2009); Syed et al, (2012) in chickpea; Arya et al, (2017) in wheat, Gowsalya et al, (2017) in black gram, Wankhade et al,2017 in clusterbean. According to Temesgen et al, (2015) increasing parental distance implies a great number of contrasting alleles at the desired loci and then to the extent that these loci recombine in the F 2 and F 3 generation following a cross of distantly related parents, the greater will be the opportunities for the effective selection for yield factors.…”
