Abstract

Genetic variability, heritability, interrelationships and diversity analysis for seed yield and its components were estimated in 31 promising lines of chickpea grown under rice fallow on first fortnight of December. Highly significant differences existed among the genotypes tested for all the traits. Traits seed yield per plant, biological yield, and number of effective pods, total number of pods, 100-seed weight, harvest index and number of secondary branches showed high phenotypic and genotypic coefficient of variation, heritability and genetic advance as percentage of mean. Significant and positive correlations were found between seed yield and biological yield, total number of pods per plant, harvest index, number of effective pods, 100-seed weight, number of secondary branches, number of primary branches and number of seeds per plant, while negative with phenological traits. Protein (%) showed significant negative correlation with 100-seed weight. Ideal plant type in late sown under rice fallows would be early in phenological traits having high biomass, harvest index and more number of effective pods. D2 analysis grouped 31 promising lines into thirteen clusters. Genotypes JSC55, AKG 70, BGD 1064, BG 256, RVSSG 8, H 07-120, Phule G 00-108, BG 3005, JG 92-3974, CSJ 313 and BGD-1056 were identified as promising based on the mean performance of different yield attributing characters and high nutritive values, may be utilized in chickpea improvement.
