- Breeding new improved clones for strawberry production in Brazil Alexandre Gonçalves Galvão Luciane Vilela Resende Wilson Roberto Maluf Juliano Tadeu Vilela de Resende Andrew Kim Lopes Ferraz Josué Clock Marodin Agrociencias Crossing Crossing heterosis heterosis fragaria x ananassa Duch 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. 2017 artículo científico 1679-9275 https://www.redalyc.org/articulo.oa?id=303050431003 https://www.redalyc.org/journal/3030/303050431003/ https://www.redalyc.org/journal/3030/303050431003/html/ https://www.redalyc.org/journal/3030/303050431003/303050431003.epub https://www.redalyc.org/journal/3030/303050431003/movil en http://www.redalyc.org/revista.oa?id=3030 Acta Scientiarum.
