SEED YIELD OF PINTO SLOW DARKENING BREDING LINES IN CHIHUAHUA STATE, MEXICO

摘要

In Chihuahua State —northern Mexico— significant advances has been observed for total area planted with Pinto Saltillo bred cultivar in response to domestic bean market (Avila et al., 2009). Based on farmers demand INIFAP's breeding program developed several slow darkening improved lines, similar to Pinto Saltillo, but with larger seed size (> 36g/100 seeds). Validation is needed in order to evaluate adaptation of pinto bred lines across dry bean producing areas from Chihuahua. The objective was to select pinto improved lines based on earliness, disease tolerance, seed yield, slow darkening and seed size.
