The use of glyphosate-resistant varieties in northwestern Argentina (NWA) has experienced a remarkable increase in recent years. Currently, over 98% of the soybean area in this region is occupied by these transgenic varieties (Devani et al., 2001). The excellent results obtained with varieties from maturity groups shorter that those traditionally used in the area and the emergence of the first glyphosate-resistant varieties, resulted in the rapid adoption of cultivars from maturity groups V, VI, and early VII, instead of VII and VIII. (Devani et al., 2000). The soybean breeding project of the Estación Experimental Agroindustrial ?Obispo Colombres? (EEAOC) developed locally Munasqa RR, a new soybean cultivar resistant to glyphosate, witch adds another option to the current offer of long cycle materials for NWA (group VIII). In addition to resistance to the main diseases of the region, Munasqa RR has show great adaptation, stability, and high yield potential throughout NWA (Devani et al., 2001b).
