1. ImplicaÃÃes do nÃmero de intercruzamentos nas propriedades genÃticas de uma populaÃÃo segregante de feijoeiro / Implications of the number of intercrossings in the genetic properties of a common bean population.
In autogamus species, like common bean na usual question about the breeding program based on hybridization, in the necessity to intercross plants of the F2 generation. The objective of this research was to verify the effect of 0, 1 and 2 intercrossings on the genetic properties of a common bean segregating population derived from multiple crossings. A involv

2. Natural selection and the breederâs decision about the best moment to extract families in common bean. / SeleÃÃo natural e a decisÃo do melhorista sobre o melhor momento de abrir o Bulk na cultura do feijoeiro
The âbulkâ method presents some advantages, including the versatility in extracting families at any moment. Theoretically there is no justification in delaying line extraction beyond the F5 generation, but if there is action of natural selection in the direction required by the breeders, a question of whether delaying line extraction would increase the cha
