Selection of peach clones for productivity, adaptability and stability

Abstract

This study aimed to estimate genetic and phenotypic parameters of features related to productivity in peach clones and study the applicability of the statistics MHVG, PRVG and MHPRVG, with the aid of BLU/REML procedure, on the identification of clones that meet, simultaneously, high productivity, adaptability and genotypic stability. 84 clones were tested in a randomized block design with three replications and one plant per plot, during two consecutive growing seasons (2007 and 2008), in Urussanga, Santa Catarina State, Brazil. The features evaluated were: fruit yield per plant (PTF) and average fruit weight (MMF). It was found that clones 57 and 51 stood out among the other evaluated; the statistics MHVG, PRVG and MHPRVG are appropriated to be used as criteria for selection of superior clones and the feature MMF was little influenced by the environment.
