title: Interspecific hybridization of Phaseolus vulgaris L. and Phaseolus angustissimus A. Gray using in vitro embryo culture.
abstract: The introgression of new desirable characters is very necessary in common bean (Phaseolus vulgaris L.)Interspecific hybridization of P. vulgaris L. with P. angustissimus A. Gray, a wild species with narrow leaves, could be successfully achieved for the first time using embryo culture. Sixteen to twenty-three-day old embryos could grow to plantlets when they were cultivated on modified Monnier's medium.The leaf shape of the hybrid plants obtained showed intermediary traits between the two parents.A chromosome stock doubling could be achieved for one embryo.
