摘要: 总结了水稻骨干亲本BG902在培育扬稻系列品种中的作用,并用来自菲律宾和中国的18个白叶枯病菌菌株对BG902和扬稻系列品种以及用扬稻6号为恢复系育成的部分杂交籼稻组合进行白叶枯病人工接种。结果表明,BG902在扬稻系列品种育成过程中起到关键性作用;骨干亲本BG902对白叶枯病的抗性在扬稻系列常规品种和用扬稻6号作为恢复系所配制的杂交籼稻组合中都获得传承;同时筛选出强致病性菌株JSA068、JSA0639、JSA0641和YNA378等。

Abstract:  The role of BG902 in the breeding of Yangdao series was summarized. BG902, Yangdao series and some indica hybrid rice  were inoculated  with  eighteen strains of Xanthomonas oryzae pv. oryzae from the Philippines and  different regions in China  with Yangdao 6 as restorer line. The results showed that BG902 has key function in the development of Yangdao series variety and its bacterial blight resistance was passed  continuously   on to  all the  tested varieties and combinations. Some strong pathogenicity strains(JSA068, JSA0639, JSA0641 and YNA378)were found, which  will be useful to rice breeding for resistance to bacterial blight.

Key words: rice, main parent, bacterial blight, resistance
