Eficiência do sistema de nove covas na seleção de progênies de feijoeiro tipo carioca para arquitetura ereta

Abstract: Resumo -O objetivo deste trabalho foi verificar a eficiência do sistema de nove covas na avaliação de progênies de feijoeiro (Phaseolus vulgaris) tipo carioca quanto à arquitetura da planta. Foram avaliadas 97 progênies nas gerações F 2:3 e F 2:4 , em delineamento de blocos ao acaso, com 20 repetições e nove plantas por parcela, em que a planta central foi avaliada, e as oito vizinhas foram consideradas conjuntamente como controle. Avaliaram-se os caracteres: produção de grãos por planta, porte e acamamento. O… Show more

“…High heritability (h 2 : 63.20 to 93.20%) for upright plant architecture traits and grain yield was obtained (Table 4). These values were similar to those reported earlier in Mesoamerican common bean experiments for lodging (Mendes et al, 2011;Jost et al, 2013;Soltani et al, 2016), insertion of the first pod (Bertoldo et al, 2010), plant height (Bertoldo et al, 2010;Carneiro et al, 2017), and grain yield (Mendes et al, 2011;Jost et al, 2013). When heritability is high, genetic variance is the main component of phenotypic variance, indicating progress in genetic breeding due to the great genetic variability observed for the traits evaluated.…”

“…The following traits: lodging, general adaptation score, insertion of the first pod, insertion of the last pod, plant height, length of second, third, fourth and fifth internodes, and the epicotyl diameter enabled to differentiate the common bean genotypes with regard to upright plant architecture. Previous studies showed that Mesoamerican common bean genotypes differed for lodging (Mendes et al, 2011;Pereira et al, 2012); plant architecture score (da Cunha et al, 2005;de Lima et al, 2012); general adaptation score (Ribeiro et al, 2010); lodging and plant height (Soltani et al, 2016); lodging, general adaptation score, and insertion of the first pod (Jost et al, 2013); insertion of the first pod, plant height, length of the second, third, fourth and fifth internodes, and the epicotyl diameter (Moura et al, 2013); lodging, general adaptation score, insertion of the first pod, insertion of the last pod, plant height, length of the second and third internodes (Ribeiro et al, 2018a). Thus, all these traits can be used for the selection of common bean lines with upright plant architecture.…”
