稻瘟病是我省水稻主要病害,时刻威胁着水稻的高产、稳产.选用抗病品种是防治的有效措施.但连续种植几年后,便丧失抗性,变成感病品种.目前生产上的威优64已变为感病品种;汕优63也开始在部分地区发病.因此,抗瘟育种仍是抗病育种的主攻目标.
Rice blast is the main disease of rice in our province, which threatens the high yield and stable yield of rice at a moment’s time.The selection of resistant varieties is an effective measure to prevent and control.But after several years of continuous planting, we lose the resistance and become the susceptible variety. Weiyou 64 has become susceptible varieties; Shanyou 63 also began to develop in some areas. Therefore, the blast-resistant breeding is still the main target disease-resistant breeding.
