| Abstract: | Rice blast caused by Pyricularia oryzae is one of the restrictive factors in production of hybrid rice and conventional rice varieties in China. Blast resistance of several sterile lines, maintainer lines and eestoreing lines and their hybrid rice was tested and charactristcs of expression of blast resistance for hybrid rice were also studied in the present paper. The research results indicated that most of the sterile lines, mainta iner lines tested showed weaker resistance and the restoring lines and hybrid rice showed stionger resistance to strains used. On the other hand, the restoring lines were the most important factor that affected the blast resistance in hybrid rice and blast resistance expressed dominance. Therefore,the more efforts should be made on the improvement of blast resistance of "three lines" and hybrid rice breeding for rice blast disease. |
