Resumen:
Abstract:In this study it was analizad
the segregation of characters in the offspring of a weed type of Phaseolus vulgaris L. var. aborigineus (Burkart)Baudet. In the F2
generation half of the plants were
isolated of the pollinators (spontaneous self-pollination). In the F3 half of
the plants were isolated and the rest were exposed to crossed pollination with
plants of a commercial cultivar of Phaseolus
vulgaris with the same flowering phenology; seeds of both treatments were
sown in the next year. The plants of the F4 generation were maintained isolated
of the pollinators. The plants produced by the cross pollination treatment were stronger than the parental plants, and in
their seeds it was observed the
existence of addition of characters, desirables in plant improvement, the
culture of their offspring will allow to analyze the stabilization of these
characters
