| Abstract: | From 1993 to 1996, 806 rice germplasms of Dian-type japonica hybrid rice were tested for rice blast resistance with seven dominant physiological strains of Pyricularia grisea (A 1,B 13 ,C 13 ,D 1,E 1,F 1,G 1) in Yunnan Province. It was found that 64 of them were resistant to six or seven races of Pyricularia grisea. The contribution of restorer lines to F 1 hybrids in blast resistance was highly important. The breeding strategy to control blast disease was put forward by using restorer lines to layout blast resistant genes of japonica hybrid rice. |
