However, varieties with a single resistance gene may lose their resistance if a new virus strain can overcome the Stv-bi, it is necessary to identify and exploit new genetic resources which are resistant to RSV in rice breeding programs.

- 目前主要是通過(guò)傳統的雜交育種來(lái)選育抗病新品種,但效率較低而且抗病鑒定也比較困難,而利用現代的基因工程技術(shù)來(lái)快速改良高產(chǎn)優(yōu)質(zhì)但感病的水稻品種則具有廣闊的應用前景。 所以本研究圍繞條紋葉枯病抗性育種開(kāi)展了兩個(gè)方面的研究:一是尋找并定位新的抗病基因;
