Plant phenotypic variation of two half sib families of feijoa (Acca sellowiana Berg.) from an orchard in São Joaquim, SC

Feijoa (Acca sellowiana Berg.) is a native Myrtaceae of the Brazilian Southern plateau with secondary dispersion in Uruguay and its fruit has a unique flavor. Plants of a commercial orchard of this species originated by two half-sib families (FMI1 and FMI2) were evaluated, with the objective to characterize the phenotypic variation of several traits. The means (±standard deviation) of the evaluated traits, obtained in 2000 were: productivity (29.2±35.0 and 55.1±53.4 fruits per plant); height (2.2±0.7 m and 2.7±0.8 m), canopy diameter (1.9±0.7 m, and 2.1±0.7 m), number of ramifications at 20 cm of the soil (2.4±1.5 and 1.6±1.2) and distance between the stigma and the anthers in the flower (0.5±0.2 cm and 0.2±0.2 cm) for FMI1 and FMI2, respectively. The evaluations revealed significant statistical differences between the two families for plants traits evaluated, except for canopy diameter. The correlations among vegetative traits were not significant, except for height x distance between stigma and anthers (r=-0.53) for FMI1 in 2000. The regressions were not significant, except the regressions between height and productivity for FMI1 in 1998 and between productivity and distance between stigma and anthers in FMI2, in 2000, all with R² <0.15.
