本文比较分析了８１６９－２２和丙８８１２２两个水稻品种的抗虱性能。结果表明，二代褐稻虱短翅型、长翅型成虫在丙８８１２２的产卵量只相当于８１６９－２２上产卵量的４５．０２％和４０．９８％；其卵孵化串分别比８１６９－２２上的孵化率低１７．４４％，１９．７６％；短、长翅型成虫处理的若虫存活率分别比８１６９－２２品种低２５．８６％，１８．６１％。大田普查，丙８８１２２品种上的褐稻虱数量比８１６９－２２降低６．３１～１２．３２倍。此品种对褐稻虱表现较好的抗性，在当地一般年份可不予防治。
This article comparatively analyzed the anti-lice performance of two rice varieties 8169-22 and C 88122. The results showed that the second-generation brown planthopper short-winged, long-winged adults in C 88122 oviposition amount equivalent to only 45.02% and 8.99% of oviposition on 8169-22; egg hatching than the ratio The hatching rates of 8169-22 were 17.44% and 19.76% lower than those of 8169-22. The survival rates of short and long-winged adults were 25.86% and 18.61% lower than that of 8169-22. Daejeon census, C 88122 varieties on the number of brown planthopper than 8169-22 to reduce 6.31 to 12.32 times. This species showed better resistance to brown planthopper, and could not be controlled in the local general year.
