Abstract

Mango is one of the most important commercially grown fruit crops in India with greatest collection of varieties. Genotypes does not show same response in all locations due to their interactions with the surrounding environment. Presence of such interactions limits the breeding progress during selection of superior genotypes. Multi location trials are being carried out to study the behaviour of genotypes over different environments. Genotype environment interaction is a major problem in selecting and recommending superior genotypes for the cultivation of crops. This problem gets intensified, when we are dealing with perennial crops like Mango because choosing unstable cultivars to plant in an orchard puts the farmers in a risky income situation for many years. In the present investigation, an attempt has been made to identify the high yielding and stable genotypes of mango by using Eberhart and Russell’s stability model. Data on sixteen genotypes of mango tested across four locations

Keywords

Adaptability, Genotype × Environment interaction, Mango, Perennial, Stability.

Conclusion

Considering the overall performance, Mallika was found to be the stable genotype for cultivation under unfavourable environmental conditions, while the genotypes Vanraj and Totapari were suitable for cultivation under favourable conditions. None of the genotypes were stable across all test environments, hence the emphasis should be laid on the need for environment specific genotypes.
