Phenotypic stability of strawberry cultivars assessed in three environments
We examined the agronomic performance and stability of strawberry cultivars in three environments, using the Annicchiarico and AMMI methods. Thirteen strawberry cultivars were evaluated (Aromas, Oso Grande, Dover, Sweet Charlie, Tudla, Festival, Camarosa, Monterey, Palomar, Portola, Camino Real, San Andreas and Albion), in the towns of Lavras-MG, Guarapuava-PR and Uberlândia-MG. The experimental design was blocks with randomly distributed treatments, with four replications and 18 plants per experimental unit. The total number of fruits (TNF) plant-1, total mass of fruits (TMF) g plant-1, number of commercial fruits (NCF) plant-1 and mass of commercial fruits (MCF) g plant-1 were evaluated. Variance analysis detected a significant effect for cultivar, environment, and cultivar x environment interaction for all the characteristics. The agronomic performance of the Dover cultivar stood out for TNF, TMF and NCF, while the Camarosa cultivar stood out for MCF. When we examined phenotypic stability in terms of yield in different cultivation environments, the Albion cultivar stood out for TMF, and Monterey and San Andreas for NFC.
