The basic concepts of the genetic improvement of beans through hybridization are described. In general, the breeding process involves the following phases: (1) development of exptl. lines, (2) evaluation of exptl. lines and identification of new cv., and (3) commercialization of new cv. The main ...

Nineteen early maturing, indeterminate common bean parents were crossed with a tester line of normal maturity. All parents, F1 hybrids, F2's, and backcross generations were evaluated at CIAT-Palmira, Colombia. All 19F1 populations flowered and matured almost as early as the respective early paren...

El frijol (Phaseolus vulgaris L.) cultivado de origen Mesoamericano tiene tres razas: Du rango, Jalisco y Mesoamérica, cada uno con sus distintas características, zonas de adaptación y problemas de producción. Los cultivares de semilla mediana (Flor de Mayo, Garbancillo Zarco) de raza Jalisco tie...
