Abstract

In the south of Brazil, the development of agroforestry systems (AFS) lacks knowledge about the adaptation of species. Feijoa [Acca sellowiana (O. Berg) Burret] is a fruit species, listed as being capable to use for AFS. In order to evaluate the performance of segregating populations derived from two crosses between selected genotypes (C1 and C2), established experimental plots under AFS in five farms were evaluated with traits of indicative vegetative growth, earliness and yield. The average mortality was 46% influenced by the cultivation environment with no difference between progenies of the crosses C1 and C2. The cultivation environment here is defined by soil and climate conditions of each site, as well as the structure of the AFS and the management adopted by the farmer. Plants crossing C1 flourished and produced nearly as twice as many fruits as compared to C2. C1 in general, showed greater variability and better performance for evaluated traits at Paraí location, a place that best discriminate the segregating populations. Thus, selection can be made and should be prioritized for the progeny from crossing C1 at Paraí cultivation environment that presented the best contrasts.
