Análise da adaptabilidade e estabilidade de produção em ensaios regionais de feijoeiro para o Estado de São Paulo

Abstract

Analysis of adaptability and yield stability in regional trials of common bean for the state of São Paulo, BrazilThe objective of the present study was to identify superior genotypes for yield, adaptability and stability in common bean yield using the Lin & Binns (1988) analysis modified by Carneiro (1998). Twenty-two genotypes were analyzed from the main Brazilian plant breeding programs.

Genotype-environment interaction in common bean cultivars with carioca grain, recommended for cultivation in Brazil in the last 40 years

“…The coefficients of variation (CVs) were low (7.5 ~ 14.1%), indicating good experimental accuracy and reliability of results. In studies with common bean, Oliveira et al (2006), Silva et al (2013), Menezes Júnior et al (2013) and Domingues et al (2013), found CVs between 6-23% for grain yield. The grain yield varied between experiments and means were highest in the dry and winter seasons in Coimbra (3571 and 3153 kg ha -1 , respectively).…”

“…In common bean, Dalla Corte et al (2002), Carbonell et al (2004, Oliveira et al (2006), Pereira et al (2009), andSilva et al (2013), among others, carried out research of this nature. However in these studies, most genotypes tested were lines of a particular breeding program, which were often not released on the market.…”

Simultaneous selection in beans for stability and high agronomic performance

“…A significant C x E interaction has previously been described for flowering (Mambrin et al, 2015), cycle Ribeiro et al, 2004Ribeiro et al, , 2014, insertion of the first pod (Ribeiro et al, 2014;Maziero et al, 2015), and grain yield (Elias et al, 2007;Melo et al, 2007;Rocha et al, 2010;Pontes Júnior et al, 2012;Domingues et al, 2013;Silva et al, 2013;Pereira et al, 2009aPereira et al, ,b, 2010Pereira et al, , 2014Barili et al, 2015a,b) in experiments evaluating the performance of common bean cultivars. The existence of a significant C x E interaction indicates that the stability analyses may be useful for the identification of superior cultivars.…”

“…The stability of common bean grain yield has been extensively evaluated using the Eberhart and Russell (1966), Lin and Binns (1988), and additive main effect and multiplicative interaction (AMMI) methods (Carbonell et al, 2007;Melo et al, 2007;Pontes Júnior et al, 2012;Domingues et al, 2013;Silva et al, 2013;Pereira et al, 2009aPereira et al, ,b, 2014Barili et al, 2015a,b). Cycle stability in common bean has been studied using the Eberhart and Russell (1966) method, although few environments were considered (Ribeiro et al, 2004).…”

Adaptabilidade e estabilidade e a produtividade de grãos em cultivares de feijão preto recomendadas no Brasil nas últimas cinco décadas

“…Porém, a análise de estabilidade e adaptabilidade é uma alternativa para amenizar os efeitos da interação e identificar cultivares com comportamento previsível e responsivas às melhorias do ambiente (CRUZ & REGAZZI, 2001). Tal estimação fornece informações detalhadas sobre o comportamento das cultivares e contribui na sua caracterização quanto à resposta às variações ambientais, proporcionando maior segurança na recomendação (SILVA et al, 2013).…”
