5个水稻材料对褐飞虱及白叶枯病的抗性评价
Resistance evaluation of five rice varieties to brown planthopper (BPH) and bacterial leaf blight (BLB)
摘要
Abstract
[Objective]An experiment was conducted to evaluate rice resistance to brown planthopper (BPH) and bacterial leaf blight (BLB) in order to provide references for breeding rice varieties resistance to BPH and BLB. [Method] Five conventional rice varieties viz., 9311 (no anti-brown planthopper gene), Mudgo (with Bphl), Rathu Heenati(with Bph3) , Swarnalata(with Bph6) and Pokkali(with Bph9) were used to identify resistance to BPH [mixed-biotype of nanning] and BLB [strong-pathogenic bacteria of Fangchenggang] using seedling bulk test and artificial clipping leaf method with phosphorus stress. [ Result ]The rice lines (Pokkali, Swarnalata, Rathu Heenati and Mudgo) were moderately resistant to BLB under 40 mg/L of phosphorus stress, and high resistant to BLB under 0.25 mg/L of phosphorus stress. Pokkali showed high resistance in conventional BPH identification and BLB under phosphorus stress. [Conclusion ]It could be an effective way to improve rice resistance to BLB under low phosphorus stress. Considering its high resistance to BPH and BLB, Pokkali could be used as resistant breeding material.关键词
