Associação entre arquitetura de planta e produtividade de grãos em progênies de feijoeiro de porte ereto e prostrado

Abstract: Resumo -O objetivo deste trabalho foi avaliar se progênies de feijoeiro de porte ereto e prostrado de um mesmo grupo gênico apresentam o mesmo potencial produtivo. Realizaram-se cruzamentos entre uma cultivar de porte prostrado e três de porte ereto, e foram obtidas três populações até a geração F 5 , quando foi realizada a seleção de plantas eretas e prostradas de cada população. Essas plantas foram avaliadas em experimentos distintos. Nas gerações F 5:6 , F 5:7 e F 5:8 , foram avaliados o porte da planta, co… Show more

“…These estimates allowed to infer that it is possible to obtain erect plants without expressive yield reduction, as suggested by Collicchio et al (1997) and Silva et al (2009), and also that selection for Carioca-type beans can be made without any effect on plant architecture or grain yield.…”

“…Erect cultivars facilitate cultural practices, enable mechanized harvesting, and ensure higher quality grains (Mendes et al, 2009;Silva et al, 2009;Zilio et al, 2013). Unfortunately, the evaluation of plant architecture by visual grade (Collichio et al, 1997) is more propitious to error, as it requires the evaluators to have experi-ence and training.…”

“…However, cultivars of carioca-type bean present some problems, such as a high degree of lodging. Cultivars with the most suitable plant architecture, particularly the erect cultivars, enable mechanized harvesting, a reduction in production loss, and enhanced grain quality (Cunha et al, 2005;Menezes Júnior et al, 2011;Silva et al, 2009Silva et al, , 2013aMoura et al, 2013). Thus, selecting plants with more erect plant architecture has received great attention from bean breeders (Kelly and Adams, 1987;Menezes Júnior et al, 2008).…”

“…Conforme destacam Silva, Abreu & Ramalho (2009), a demanda por cultivares, com arquitetura de planta que facilite os tratos culturais e a colheita, é bastante elevada. Plantas com o porte mais ereto têm sido uma das principais exigências, tanto dos empresários rurais quanto dos agricultores familiares.…”
