“…Como o desempenho relativo das características agronômicas das cultivares (produção de grãos, teor e rendimento de óleo, dentre outras) pode variar de um ambiente de cultivo para outro, faz-se necessário um estudo multi-ambiental, ou seja, que diferentes cultivares sejam testadas em diferentes locais, anos, épocas, tecnologias, etc (CRUZ; REGAZZI, 2006;MAEHLER et al, 2003;MINUZZI et al, 2009;PEREIRA et al, 2008;DUARTE, 2006).…”

Palavras-chaves -Soja. Agricultura e energia. Biocombustíveis. Semeadura. Abstract -The sowing season is defined by a set of environmental factors that react with each other and interact with the plant, thus affecting variations in production and other agronomic traits. This work was carried out to evaluate the behavior of 21 cultivars of commercial soybean, during different times, looking forward to the production of biofuel. Were conducted five essays in the 2008/09 agricultural year, being two of them in Palmas-TO and three in Gurupi-TO. The sowing in Gurupi-TO was in

“…Entretanto, tal procedimento poderia representar um custo muito elevado ao agricultor, o que poderia tornar sua execução impraticável (PEREIRA et al, 2008). Porém, a identificação de cultivares, com maior estabilidade fenotípica, tem sido uma alternativa muito utilizada para atenuar os efeitos da interação genótipos com ambientes e tornar o processo de indicação de cultivares mais seguro (RIBEIRO et al, 2008).…”

“…The selection of genitors to be crossed is crucial because it determines the success of others and, consequently, the efficiency of the breeding program (Bertan et al, 2007;Pereira et al, 2007). A strategy commonly used for genitor selection is diallel crossing.…”

ABSTRACT. The objective of this study was to select genitors based on F 1 and F 2 generations, evaluated in different environments, to obtain segregating populations for the identification of strains showing improved earliness, yield, and carioca-type grains. Nine bean strains were crossed in a partial diallel scheme (4 x 5), in which group 1 included 4 strains with early cycles and group 2 included 5 elite strains. The F 1 and F 2 generations and the genitors were assessed in Coimbra and Viçosa in randomized blocks with 3 replications. The following characteristics were evaluated: days between sowing and emergence, and grain yield. We observed an interaction between the effects of general combining ability and specific combining ability with the environments (crop, location, and generation) for both grain earliness and yield. Genetic analysis of earliness revealed a predominance of additive effects and grain yield dominance effects. The strain Goiano Precoce may be used as a genitor in breeding programs to improve earliness, while strains RP1 and VC33 can be used to increase grain N.M.

We observed genetic complementation between strains Goiano Precoce and RP1, BRSMG Madrepérola and BRS Estilo for earliness and between RP1 and Rosinha Precoce for grain yield.
