Identification of novel source of Rice Stripe Virus resistance

Rice stripe virus (RSV) is one of the major constraints which is transmitted by the small brown planthopper (SBPH; Laodelphax striatellus). Typical symptoms of RSV are chlorosis and weakness of newly emerged leaves, white and yellow spots, stripe and necrotic on leaves, necrotic and wilting leaves, as a consequence, plant growth decline and the contaminated plants are gradually die. (Takahashi et al. 1991). In our previous study, we screened 6 RSV resistant cultivar including ‘Padi Adongumarat’, ‘Pervomajszkij’, ‘Tung Ting Wan Hien 1’, ‘02428’, ‘Erguailai’, and ‘Daw dam’, which harbors different resistance allele with Stv-bi. In this study, we further classified the resistant varieties by using MAS and sequence analysis on Stv-b(Lee et al., 2017) and OsSOT1(Zhang et al. 2014) to diversify resistance genes of rice stripe virus.
