GENOTYPE - ENVIRONMENT INTETRACTION ON SEED YIELD AND YIELD CONTRIBUTING CHARACTERS IN CHILLI (Capsicum frutescens L.)

Abstract

An experinient was conducted at the experimental field of Sher-e-E3angla Agricultural University during rabi, 2013-2014 with ten chilli (C.'apsicwn frulescens L.) genotypes oftlifferent sources. It was laid out in randomized complete block design with three replications and four environments, to find out genotype or genotypes with high mean yield and good adaptation to different environments and assessment of the genotype and environment effect on chilli. Data were collected on several inorpho-physiological yield contributing parameters. The Additive Main Effects and Multiplicative Interaction (AMMI) statistical model was used to describe Genotype x Environment Interaction (GFil) and adaptation to certain environments. The combined analysis of variance (ANOVA) indicated significant differences between genotypes and environments as main effects. GE! both linear and non- linear components were highly significant for most of the parameters except number of seeds per fruit and hundred seed weight. Env-3 and Env-4 were poor and Env- I and Env-2 were found to he rich and Iävorable for chilli production. Where, Env-2 was found highly favorable for chilli production. The stable genotypes found were DI3P 14 50 (China). E3D-2059 and J3ogura Jan, exhibited intermediate mean yield and could he adopted for general cultivation. Kalo Dhawna morich. [logurar Lomba Morich and Bullet exhibited coniparativelv higher mean yield but were unstable across the environments and can be recommended to cultivate in rich environments.
