Abstract:
Carrot (Daucus carota L.) is a popular root vegetable crop suitable for tropical and temperate climate, grown throughout the world. The success of carrot crop improvement and production activities can be enhanced with scientific information generated form genotype-environment interactions (GEI). The present research was carried out to find the stable and adaptable carrot genotypes under three different agro-ecologies. Seven genotypes were evaluated in randomized complete block design (RCBD) with three replications. Eberhart and Russell model stability indices were used to evaluate stability and genotype by environment performances. Combined analysis of variance (ANOVA) for yield components traits revealed highly significant (P≤ 0.01) differences for genotypes, environments and their interaction. The significant interaction showed genotypes respond differently across environments. None of the genotype was found stable for all the traits across all the environments and stability of each trait was independent from one another in three different locations.
