| 摘 要： | Objective] This study was to breed rice cultivars with multi-resistance to Orseolia oryzae (Wood-Mason). Method] The Guangxi local cultivar GX-M001(Jiangchao) with high resistance to Orseolia oryzae (Wood-Mason) was used to hybrid with the known resistance cultivars "Kangwenqingzhan" (harboring GM6 gene), OB677(harboring GM3 gene) from Sri Lanka, HT1350 and high yield and quality cultivar "Guiruanzhan". Result] Through pyramiding the multi-resistant genes via routine hybridization, the general resistances of the hybrids were remarkably enhanced. The grades of resistance were also improved, many of the combinations were endowed with a resistance at immune level(grade 0); and interestingly, the respective hybridization of GX-M001(high resistance) with OB677(medium resistance) and HT1350(susceptible) also generate two lines at immune level, which is probably the effects of additive effects of genes. Conclusion] By routine hybridization, multiple genes were successfully pyramided, thus generating novel rice lines with multiple resistances. For the rice breeding scientists at the grass-roots level, the resistance-resistance pyramiding is an effective approach to breed high resistance cultivars.
