Fig. 1From: Recent progress on the genetics and molecular breeding of brown planthopper resistance in riceFrequencies of rice accessions resistant to different BPH biotypes. The data were partially selected and summarized from the Genesy database (https://www.genesys-pgr.org/zh/welcome). The total of 573 cultivated rice accessions showed resistance to at least one biotype. Biotype 1, Biotype 2 and Biotype 3 represent the number of cultivars only resistance to biotype1, 2 or 3 of BPH, respectively. 1 + 2 + 3 denotes the number of cultivars resistance to all three biotypesBack to article page
