Study on genetic diversity in chilli (Capsicum annuum) based on multivariate analysis and isozyme analysis
Journal Title: Journal of Applied and Natural Science - Year 2016, Vol 8, Issue 4
Abstract
Thirty seven diverse chilli (Capsicum annuum) genotypes were studied for 22 growth, yield and fruit quality traits. Multivariate analysis grouped the genotypes into 7 clusters. Cluster IV was largest containing 14 genotypes. Inter cluster distance was maximum between cluster V and VII (248.09), and minimum between cluster I and II (57.80). Cluster VII was most heterogeneous (intra-cluster divergence value 191.25) and Cluster II was most homogeneous (30.25). Genotypes were also analyzed for peroxidase enzyme polymorphism using gel electrophoresis which resulted seven electrophoretic bands (Rf 0.19 to 0.59) and grouped the genotypes into 6 zymotypes. Zymotype P4 included maximum (13) number of genotypes. Number of clusters in peroxidase and multivariate analysis were almost same but distribution of genotypes varied. 73% of total genotypes showed similar pattern of grouping suggesting that the two methods are complementary to each other and should be carried out simultaneously to determine genetic diversity more effectively. Considering variability and diversity analysis of the genotypes, CUCH-4 from Cluster-II (& Zymotype-P2) and CUCH-31, CUCH-34 and CUCH-35 from Cluster-VII (& Zymotype-P4) were identified as promising genotypes which can be used in further crop improvement programme.
