Genotype x Environment Interaction Effects on Yield and Related Traits of Cassava (Manihot esculenta Cranz) in Nigeria
Abstract
A significant genotype by environment interaction (GEI) presents challenges in the selection of superior genotypes. The objective of this study was to evaluate the stability of 12 improved cassava genotypes by examining their performance for yield and related traits in three environments. Accordingly, 12 cassava genotypes were evaluated to assess genetic variability for root yield and its components at three locations (Umudike, Otobi and Igbariam) in Nigeria during the 2018 – 2019 cropping season. This research was carried out to study the stability performance for cassava root yield and its components using a Randomized Complete Block Design. Genotype x Environment interaction was significant for all the traits studied, indicating considerable influence of the environment on the expression of the traits. The genotype by environment interaction effect was significant for all the traits studied.
