Ammi Analysis for Fruit Yield Stability of Paprika (Capsicum Annuum Var Longum L.)

Genotype × Environment interaction of five parents and four F₁ hybrids along with check at four environments for paprika fruit yield was studied with Additive Main Effects and Multiplicative Interaction (AMMI) model. The four paprika hybrids along with their parents were raised in a randomized complete block design with three replications taking care of sowing in the month of June 2007 in all the locations. The combined analysis of variance of AMMI showed that the environment, genotype and G × E interaction were highly significant, suggesting a broad range of genotypic diversity and environmental variation. Three parents viz., Bydagi – kaddi, Simla Paprika and KTPL – 18 were found to be stable across environments for number of fruits per plant. The parent Arka Abir was found to be stable yielder across environments. The hybrid Arka Abir × Bydagi – kaddi cross was stable for the maximum three characters over environments and identified as having general adaptability. The results of environmental index (I) for fruit yield calculated as deviation of the mean of all varieties at particular environment from the grand mean revealed that location Thadiyankudisai recorded substantial increase in the values.
