| O objetivo deste trabalho foi estimar o progresso genético após três ciclos de seleção recorrente na cultura do feijoeiro. Em cada ciclo, as progênies foram avaliadas por três gerações S0:1, S0:2 e S0:3, no campo experimental do Departamento de Biologia da Universidade Federal de Lavras (UFLA), em Lavras, Minas Gerais, no período de 2001 a 2006. Nos experimentos, avaliaram-se a produtividade de grãos, a arquitetura da planta e o tipo de grão. Em todas as avaliações de progênies, foram realizadas as análises de variância e obtidas as estimativas de parâmetros genéticos e fenotípicos. Foi estimado o progresso por caráter e, posteriormente, para os três caracteres, simultaneamente, após a padronização das variáveis. Como os ciclos foram obtidos em anos... |

| ABSTRACT The black-eyed cowpea, is consumed in Brazil and valued in various other countries, and for this reason, can be found on the domestic market, showing the potential for export. The aim of this study was to identify lines of the black-eyed cowpea having high productivity and quality commercial grain. Twenty-four lines of black-eyed commercial subclass of cowpea, taken from the breeding program of Embrapa Meio-Norte, and two controls (BRS Itaim and CB-27) were evaluated. The experiments were carried out in Nova Ubiratã, in the State of Mato Grosso, Brazil (MT) during 2014, and in Primavera do Leste MT and Sinop MT during 2015, in the off-season; planting was in February/March and harvesting in May/June. The experimental design was of randomised... |

| In common bean (Phaseolus vulgaris L.) breeding, plant selection that associate erect plant architecture, high yield, and grains with good commercial acceptance has been the choice of breeders. Thus, this study aimed to evaluate potential parents, to obtain promising segregating populations that associate high yield, erect plant architecture and carioca grain type, as well as to obtain information on heterosis, general and specific combining ability of these parents regarding grain yield and traits related to plant architecture. Fourteen common bean lines were crossed under a partial diallel scheme. Group 1 was composed by eight erect plant lines and group 2 by six carioca grain type lines. The F1's plants from the crosses and the 14 parents were evaluated... |
