Genetic progress resulting from forty-three years of breeding of the carioca common bean in Brazil
“Genetic progress resulting from forty-three years of breeding of the carioca common bean in Brazil”, vol. 15, p. -, 2016.,
We aimed to evaluate 40 common bean cultivars recommended by various Brazilian research institutions between 1970 and 2013 and estimate the genetic progress obtained for grain yield and other agronomic traits. Additionally, we proposed a bi-segmented nonlinear regression model to infer the year in which breeding began to show significant gains in Brazil. The experiment was carried out in Viçosa/MG and Coimbra/MG, in the dry and winter seasons of 2013. For this, a randomized complete block design with three replications was employed.
