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.
