Abstract

Abstract: The objective of this work was to evaluate the interaction between genotypes and environments for grain yield of common bean (Phaseolus vulgaris) lines and cultivars with potential for use in family farming systems. Data from value for cultivation and use tests, carried out in 20 environments in the state of Goiás, Brazil, were analyzed in two cycles (2007/2008 and 2009/2010) in the dry, rainy, and winter crop seasons. Each test consisted of 15 genotypes from the carioca, purple, and rosinha common bean commercial groups. The experimental design was randomized complete block, with three replicates. The methodologies used to test the stability and adaptability of the genotypes were the one of Lin & Binns, of Cruz, the additive main effects and multiplicative interaction model (AMMI) to calculate the weighted average of absolute scores and productivity (WAASP), and the GGE biplot graphical analysis. The productive performance of the common bean lines and cultivars is affected by genotype x environment interaction. The methodologies adopted allow the selection of cultivars for cropping, and of cultivars and lines for use as parents in order to obtain segregating populations for selection in a family farming system.

Highlights

Brazil stands out as one of the world’s largest producer and consumer of common bean (Phaseolus vulgaris L.), with an average productivity of approximately 1,400 kg ha-1 when considering the three recommended sowing seasons (Silva & Wander, 2013)
There are no consistent reports in the literature for the specific conditions of the family farming system, because common bean breeding programs focus on genotypes with an extensive range of adaptation (Torga et al, 2013a; Pereira et al, 2016)

Summary

Introduction

Brazil stands out as one of the world’s largest producer and consumer of common bean (Phaseolus vulgaris L.), with an average productivity of approximately 1,400 kg ha-1 when considering the three recommended sowing seasons (Silva & Wander, 2013). These seasons – rainy, dry, and winter – are responsible for 41.7, 36.7, and 21.6% of total production, respectively (Torga et al, 2013b; Feijão, 2016), supplying the domestic market all year round. There are no consistent reports in the literature for the specific conditions of the family farming system, because common bean breeding programs focus on genotypes with an extensive range of adaptation (Torga et al, 2013a; Pereira et al, 2016)
