| Abstract: | In this study,the resistance of 212 rice varities,which were used in molecular breeding program,were screened at blast nursery in Liaoning Province.The results showed that 117 and 39 varieties were resistant to Magnaporthe grisea at the seedling stage and adult stage,respectively.There was significantly correlation between the resistance at the two stages,and among them,19 varieties exhibited mid-resistance to leaf blast and panicle blast.In addition,the resistance of 19 rice varieties was further evaluated... |
