Resumen
Descripción
Breeding different strawberry genotypes and pl ant selection in Brazil could result in new cultivars with better environmental adaptations. The aim was to develop and select new F 1 strawberry plants with higher potential yields. Twelve hybrid populations were obtained from breeding the cultivars Aromas, Camarosa, Dover, Festival, Oso Grande, Sweet Charlie and Tudla, and 42 F 1 hybrids were obtained from each population. An augmented randomized block design was used. Productive traits were measured and heterosis was calculated for all trai ts. The breedings Dover x Aromas and Camarosa x Aromas both showed 28.6% of their hy brids with a total fruit mass that wa s higher than that of cv. Aromas, and 9.5 and 14.3% were higher than that of cv. Camarosa, respectively. The breeding of Camarosa x Aromas produced hybrids with high potential yields and a large average fruit mass that reached the commercial standard. Hybrids MCA 12-93, MFA12-443 and MCA12-89 showed high potential yields and can be used as parents in strawberry breeding programs.
