title: Prospects for interspecific hybridization of Lupinus atlanticus Gladst. with L. cosentinii Guss.
abstract: Successful crossing is reported between L. atlanticus Gladst. (2n = 38) and L. cosentinii Guss. (2n = 32), using lines of both species selected for crossability followed by selection of relatively fertile progenies. In one cross, 82E75, from a single F2 segregating plant, 22 F3 seeds were obtained. Some other less crossable combinations were completely sterile in the f1 or F2. Backcrossing to both parent species was successful, but some crosses gave relatively more seed by using F2 plants for backcrossing rather than F2's. It is concluded that potential exists for introgression of useful genes in both directions.
