Title : Study of genetic diversity in char land chilli

Abstract:

The experiment was conducted at Spices Research Centre, Shibganj, Bogra during 2015-2016 with a view to study the genetic diversity and selection of suitable genotype for future breeding program. Ninety five chilli lines of char land were used in this study. D² analysis of 95 chilli lines and analysis of variance were done. The lines were grouped into seven clusters. It was found that the inter-cluster distance was larger than the intra-cluster distance. The highest intra-cluster distance was observed in cluster I(1.0953) and the lowest was in cluster III (0.533).The highest inter-cluster distance was observed between clusters V and I (16.752), followed by cluster II and I (14.571), III and I (12.767), VII and V (11.305). The lowest inter-cluster distance was observed between cluster III and II (2.516) followed by V and II (2.577). It may be concluded that the cluster V and I (15) could be used for future breeding work.The experiment was conducted at Spices Research Centre, Shibganj, Bogra during 2015-2016 with a view to study the genetic diversity and selection of suitable genotype for future breeding program.
