SEED YIELD OF 'ROSA DE CASTILLA' LANDRACES FROM THE CENTRAL-WEST AREA OF MEXICO

摘要

The ancestral common bean landrace 'Rosa de Castilla' (RC) is ascribed to the Jalisco race (Singh et al, 1991). The seed of this bean type is from medium to large size (32 to 45 g/100-seed), oval shaped of dull or shiny pink-cream colors. The RC beantype is mainly grown under rainfall conditions in small areas by hundreds of farmers in the states of Jalisco, Guanajuato, San Luis Potosi (SLP) and SE Zacatecas. Landraces from Jalisco and the SW of Guanajuato, the area of bean domestication (Kwak et al, 2009; Rossi et al, 2009), are of climbing growth habit whereas those from Northern Guanajuato, SLP and Zacatecas are of indeterminate prostrate growth habit. This bean type is locally sold and consumed and can also be found in traditional markets in most large cities in Central-West Mexico, it also is appreciated by Mexican migrants that live in the USA and Canada.
