Genetic divergence in chilli (Capsicum annuum L.).

摘要

Fifty-five accessions of chilli (C. annuum) were evaluated for 15 quantitative characters, including yield. Plant height, followed by yield per plant, showed the maximum contribution towards diversity. D2 analysis grouped all the genotypes into XIV clusters with 10 solitary clusters, and the D2 values varied between 14.38 and 85.01. Cluster I was the largest containing 32 genotypes, followed by clusters II and IV with five genotypes each. The maximum intra-cluster distance was reported in cluster I, whereas inter-cluster distance was maximum between clusters VII and XI. Cluster mean analysis showed that solitary clusters, i.e. cluster XI (IC-32), cluster XII (Pusa Jwala) and cluster XIV (IC-16), were having high mean values for yield per plant, average fruit weight, seeds per fruit and fruit length.
