Genetic divergence studies for yield and quality trait in chilli. Genetic variability and genetic divergence studies for yield and quality traits in chilli (capsicum annuum L.)

      Аннотация: The present book entitled “Genetic divergence studies for yield and quality traits in chilli (Capsicum annuum L.)” comprising of eighteen genotypes was carried out at Vegetable Research Farm, SKUAST-J,India during the year 2012-13. The experiment was laid out in Randomized Block Design with three replications. The phenotypic coefficient of variance (PCV) and genotypic coefficient of variation (GCV) were high for total number of fruits per plant, fruit yield per plant, average fruit weight, number of seeds per fruit and capsaicin. High estimates of heritability were obtained for all the traits under study except for plant spread,number of primary branches per plant and plant height. Eighteen genotypes were grouped into 5 different clusters. Maximum intra cluster distance was observed in cluster IV including DKC-8, Cherry Pepper, LCA-206 and G-3 while maximum inter cluster distance was recorded between cluster IV (DKC-8, Cherry Pepper, LCA-206 and G-3) and I (SJPC, SJC-01) revealing that sufficient genetic diversity for selecting superior and diverse present and can be further exploited for any chilli improvement programme.
