Evaluation of cultivated chickpea (Cicer arietinum L.) for agro-morphological traits and resistance to rust in Northwestern Indian Himalaya uri icon

abstract

  • First successful attempt was made to grow and evaluate the twenty five cultivated chickpea genotypes for agro-morphological traits to know the nature and magnitude of genetic divergence existing among genotypes alongwith resistance to rust (Uromyces ciceris arientini) in the Lahaul valley situated in northwestern Indian Himalaya. The genotypes showed highly significant differences for all the characters studied. The twenty five chickpea genotypes were grouped into seven clusters on the basis of D2-statistics. The cluster I was largest cluster with eleven genotypes followed by cluster II having seven genotypeswhile remaining clusters accomodated one genotype each. Highest intra cluster distance was observed for cluster II followed by cluster I. Highest inter cluster distance was observed between cluster III and I V. Cluster mean was found highest for days to maturity followed by days to flowering, pods per plant and seed yield per plant. Two characters viz., pods per plant followed by seed yield per plant contributed maximum in manifestation of genetic diversity. Highest range was observed for pods per plant and seed yield per plant. Number of pods per plant had highest range and maximum phenotypic and genotypic coefficient of variation (PCV and GCV), followed by seed yield per plant. High heritability was observed for pods per plant followed by seed yield per plant and plant height. High heritability coupled with high genetic advance was observed for number of pods per plant and seed yield per plant. Three genotypes viz., ICC 3137, ICCV 9675 and ICCL 87316 were found to be moderately resistant against rust. ICCV 9675 and ICCL 87316 were found to be superior for number of pods per plant and seed yield per plant, respectively. The studies revealed ICC 3137, ICCV 9675 and ICCL 87316 as diverse genotypes moderately resistant to rust (found in different clusters II, I and IV respectively). These can be utilized as promising genotypes for future breeding and hybridization program with susceptible lines which were otherwise superior for other traits
