ABSTRACT.
Raspberry (Rubus idaeus) is an economically important crop, and its cultivation has expanded recently across temperate and subtropical regions of Brazil. There is no brazilian raspberry cultivar so far. Therefore, the indirect selection can be an useful tool to help during the breeding process. We evaluated linear and canonical correlations in primocane-fruiting raspberry cultivars in 2013 and 2014, in a completely randomized experimental design, with eight replications. The genotypes ?Alemãzinha?, ?Heritage? and ?Fallgold? were evaluated during two harvesting seasons, autumn and spring. Canonical groups were established among morphological (Group 1) and yield (Group 2) traits. In Group 1, plant yield and fruit weight were evaluated; in Group 2 the productive period, plant height, stem diameter, dry mass of pruning and plant leaf area were assessed. The linear and canonical correlations among morphological, phenological, and yield traits varied according to harvesting season. The phenological and morphological traits had greater linear correlation with yield traits in autumn than in spring. Based on our findings, to obtain more productive raspberry genotypes, plant leaf area and dry mass of pruning should be prioritized in the indirect selection. © FUNPEC-RP.
