Evaluation of advanced selections of strawberry in southern Brazil

Abstract

Strawberry cultivation is technically considered a complex activity, which demands high inputs in investment and manpower. One of the most relevant technical aspects of this crop is the choice of correct cultivars. A highly fea­sible way to obtain fully adapted genotypes with high production potential and fruit quality is to select the geno­types with best performance in the producing region itself. The objective of this work was to evaluate the ad­vanced selections of strawberry on productive performance, fruit quality and resistance to strawberry leaf spot, powdery mildew and anthracnose, under conditions of the municipality of Lages, Santa Catarina State. Eleven genotypes were evaluated, being one commercial cultivar - San Andreas - and ten advanced selections, namely: ITA 12,103-15; ITA 12,103-12; ITA 12,103-22; ITA 10,107-6; ITA 10,107-7; ITA 13,097-05; ITA 10,133-2; ITA 10,128-9; ITA 12,103-6 and ITA 10,107-12. The experimental design was in randomized blocks, with three repli­cations, and plots constituted by eleven plants. The cultivar San Andreas presented the best results for total (657.06 g plant^-1) and commercial production (547.77 g plant^-1), and number of commercial fruits per plant (30.81 fruits plant^-1). The selections ITA 10,128-9; ITA 10,133-2; ITA 13,097-5; ITA 10,107-7 and ITA 10,107-12 obtained the highest values for soluble solids content, above to 8.5 °Brix, being superior than San Andreas cultivar for this variable. The genotypes ITA 12,103-15 and ITA 10,107-12, on the other hand, were the most resistant to the dis­eases evaluated.
