Aphid resistance

特許 権利維持 Several varieties of soybean have demonstrated resistance to the soybean aphid. Resistance may be conferred by antibiosis, antixenosis, or tolerance. In some instances, such as with the soybean cultivars 'Dowling', 'Jackson', and 'Palmetto', resistance to the soybean aphid results from a combination of both antibiosis and antixenosis.[38] In the 'Dowling' cultivar, resistance is conferred by a single dominant gene (Rag1).
