摘要

The objective of this research was to study the parameters of adaptability and phenotypic stability and estimate the increase in grain yield in black common bean genotypes developed by brazilian breeding programs between the years 1960-2013. The experiments were carried out considering 38 cultivars and two lines in four different environments (Coimbra and Vicosa cities, and dry and winter seasons of 2013 year) by using a randomized block design with three replications. Results showed an effective increasing of the grain yield provided by the recommendation of new cultivars from different Brazilian breeding programs in the past five decades. In addition, the GxE analysis interaction indicated that cultivars recommended after the year 2005 were those with high average grain yield, wide adaptability and high predictability.
