Methods of Adaptability and Stability Applied to Soybean Cultivars Recommendation

Abstract

Currently, there are several methods for adaptability and stability analyses, which are distinguished according to the adopted concepts of stability and statistical principles. This study aimed to compare the adaptability and stability methods of Eberhart and Russell (1966), Cruz et al. (1989), and Lin and Binns (1988 modified by Carneiro (1998), besides to select soybean cultivars with high adaptability, stability, and grain yield. Ten trials of the competition were carried out with fifteen soybean cultivars during 2016/2017 and 2017/2018 crop seasons. The method of Lin and Binns (1988) modified by Carneiro (1998), stands out for recommendation of soybean cultivars, as it combines productivity, stability and adaptability for genotype classification, being an easy to interpret method.
