mayor heredabilidad, representadas por alto coeficiente
de repetibilidad r> 1 (Goodman y Paterniani, 1969), fueron número de nudos, longitud de las vainas, longitud del ápice de las vainas, el número de vainas por planta, la época a madurez fisiológica y el peso de 100 semillas, las cuales pueden utilizarse para estudios de similaridad morfológica y evolución.
components represented 87.31% of the total variation, which discriminated the cultivars of the colIection for Andean and Meso-American gene pool. The morphological and agronomical differences were bigger among the Andean accessions, because of its dispersion degree in the first three components, which is higher than in the Meso-American ones.
The diversity among the gene pools is represented mainly by the growth habit, precocity, foliate area, yield per plant and the number of seeds by podoThe variables of high heredability represented by high repetibility coefficient r> 1 (Goodman and Paterniani, 1969) were: number of knots, pod length, pod apex length, the number of pods per plant, time to physiological maturity and the weight of 100 seeds which can be used for studies of morphological similarity and evolution.
