EVALUATION OF BLACK SEEDED CULTIVARS FOR YIELD AND BIOACTIVE COMPONENTS IN NUEVO LEON, MEXICO

摘要

Grains of common bean (Phaseolus vulgaris) black seeded cultivars are needed as a raw material for food and pharmaceutical industries. Several black seeded cultivars have been developed by INIFAP's breeding program for the Tropics and the Highlands ofMexico (Rosales et ah, 2004). Cultivars (such as Negro San Luis) and bioactive compounds (myricetin, quercetin, saponins) have been found mainly in black commercial class (Guajardo et al., 2012). Common bean is planted in spring and summer in the Stateof Nuevo Leon under irrigation and rainfed conditions. Black seeded cultivars are considered as an option to increase yields, elaboration of processed foods and to obtain bioactive extracts. For black commercial class low prices (<5.0 MXN pesos per kilogram) and trading problems are observed during high production years. Flavonoids, saponins and other bioactive components (Guajardo et al., 2012) extracted from black seeded cultivars are actually used in pharmaceutical industry. In Northern Mexico, selection for adapted cultivars with enhanced seed yield and high level for bioactive compounds need to be done in order to supply pharmaceutical and food industry. The objective was to evaluate seed yield and levels for bioactive compounds in eight cultivarsplanted in Hualahuises, N. L.
