Breeding Short-Day Strawberry Genotypes for Cultivation in Tropical and Subtropical Regions

The main strawberry cultivars grown in tropical regions originated from breeding programs developed temperate countries, which limit the expression of their maximum productive potential when warm climates. Additionally, cultivation these depends almost entirely on imported young plants, increasing production costs. Obtaining adapted with a lower requirement for accumulation chilling hours is objective southern hemisphere. Thus, this study was to evaluate short-day genotypes, pre-selected based yield and fruit quality components through multivariate analysis, conditions. Two experiments were performed. In first one, 36 genotypes parents assessed traits (total mass, commercial mean mass fruits), soluble solids content, firmness. For selection, analysis applied using genotype (ideotype) selection index principal component analysis. second experiment, best-ranked parents, Camarosa Dover (SS), titratable acidity (TA), SS/TA ratio, ascorbic acid, phenolic compounds, total anthocyanins. To identify most promising data analyzed RVFS06CR-105, RVDA11CR-61, RVDA11CR-125, RVCS44CR-130 conditions, components. means found higher than Dover, Camino Real, Camarosa. use efficient selecting repeatability information between methods guaranteeing consistency information. selected had yields those used as control, result considering independence relation genetic material, mainly expansion area addition, are being evaluated different climate aim validating them submission registration release process farmers. they source genes crossings new selections.
