Mexico imports practically all the soy (Glycine max L.) Merr. Which requires, from 2000 to 2008, the average annual production of soybeans was only 119 924 tonnes, while imports were 3 905 596 tonnes. The soybean cultivation is one of the few growing alternatives during the summer in Sinaloa. The National Institute of Forestry, Agriculture and Livestock Research (INIFAP) has released the varieties Cajeme, Nainari (Hector) and Esperanza that tolerate the direct attack of the white fly. The whitefly (Bemisia tabaci biotype “B”) is one of the main problems that caused the reduction in cultivated area of soybeans in the northwestern part of Mexico, due to the direct damage it causes (when the sap sucks the plant loses its vigor, there is loss of flowers and yield) and the geminivirus it transmits. Because the whitefly, vector of geminivirus is a strong problem in the main producing areas of the world, an intense search of sources of resistance in the world germplasm had to be initiated, to find sources of resistance to white fly and geminivirus, in where in the spring 2000-2000, the accession of group VI PI-171443, with genetic resistance to geminivirus, was confirmed, confirming its resistance and corroborated by the enzyme-linked immunosorbent assay (ELISA), which did not detect the presence of geminivirus in the foliage (PI-171443 was obtained from the USDA-ARS soybean collection in Urbana, IL, originally collected from the Shaanxi Tianbao Soya Food Technological Research Institute in China). Once the source of geminivirus resistance was identified, crosses with local varieties were performed.
