| description | A study was initiated to determine the barriers that limit the transferences of genes between Phaseolus vulgaris and P. coccineus. The factors that determine the outcome of this crossing are the direction (success is greater when P. vulgaris is used as the mother parent) and the combination of parents. Early generations show reduced viability and fertility. This reduction is more pronounced in progenies P. vulgaris x P. coccineus subspecie coccineus compared with progenies P. vulgaris x P. coccineus subspecie polyanthus. It also depends on the combination of parents. In later generations a progressive restoration of viability and fertility was observed. The combination of parents greatly affects the type of segregation of the characteristics in progeny observed in F2 of P. vulgaris x P. coccineus subspecie coccineus crossing. Moreover, results seem to indicate that in progenies P. vulgaris x P. coccineus subspecie polyanthus there are more possibilities of recombination. Interesting materials were selected for improvement of plant architecture (resistance to lodging, long hypocotyl and epicotyl, small folioles) and disease resistance (tolerance to BGMV). Some suggestions are made on future activities of the project of interspecific crosses: multiplication and evaluation of the P. coccineus collection, studies on segregation, projects on crosses fox specific objectives.
