Abstract
Present study on the morphological characterization of chilli (Capsicum annuum L.) was conducted at Maharajpur Vegetable Farm, Department of Horticulture, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur. Utilizing 43 genotypes from different regions of Madhya Pradesh, the study aimed to enhance crop improvement programs by understanding genetic diversity. Present study was conducted on forty- three genotypes of chilli collected from Department of Horticulture, Department of Plant Breeding Jawaharlal Nehru Krishi Vishwa Vidyalaya (JNKVV), Jabalpur. Genotypes have harboured appreciable amounts of variation for morphological, growth and yield attributing traits were analyzed for Phenotypic co efficient of variance (PCV), Genotypic co efficient of variance (GCV) and heritability along with genetic advance. Genetic divergence through multivariate analysis using D2 statistics was done and clustering of forty-three genotypes was done using Tocher’s method of clustering analysis. GCV and PCV were resulted as moderate and high level whereas heritability coupled with Genetic advance were recorded as moderate to high level. 6 clusters formed in 43 genotypes using Mahalanobis D2.
