The response of cultivated soybeans (Glycine max (L) Merrill) to changes in daylenght (photoperiod) has limited its expansion to regions located near the Equator, where there is a short range between the shortest and the longest day. When soybean cultivars are introduced in regions of lower latitudes than those of their adaptation, there will be a reduction in their biological cycle followed by reduction in plant height - a decisive factor in the fully-mechanized crop. The research work on soybean breeding in Brazil has made possible to obtain new cultivars highly adapted to low latitudes. Variety trials conducted in many locations have shown the potencial for the soybean crop in the Cerrados, mostly situated in low latitudes. In this paper we discuss the results of soybean trials conducted by Centro de Pesquisa Agropecuaria dos Cerrados-CPAC (Cerrados National Research Center) at Rondonopolis (16o30' South latitude) and Diamantino (14o30' South latitude) in Mato Grosso State and at Planaltina (15o57' south latitude) in the Federal District. The adaptability of the new soybean genotypes created for low latitudes is evidenced by good agronomic characteristics and high yield ability, wich is comparable or superior to that obtained in the traditional soybean cropping area. |
