Based on the fruit of resistance breeding to rice blast in 1980’s, 12151 rice varieties/lines had been screened for blast resistance in the typical blast nursery by field resistance test with inoculation mixture of Magnaporthe grisea races from 1994 to 2003. It was indicated that 4933 lines were resistant to leaf blast and 7103 lines were sensitive to leaf blast, accounting to 40.60% and 58.46%, respectively. To neck blast, there were 4071 resistant lines and 7965 sensitive lines, accounting for 33.50% and 65.55%, respectively. The leaf blast performance of 9034 lines was consistent with their neck blast performance. Lines resistant to both leaf blast and neck blast were half of lines sensitive to both leaf blast and neck blast. The leaf blast performance of 3002 lines was inconsistent with their neck blast performance. Lines that were sensitive to leaf blast and resistant to neck blast were more than those resistant to leaf blast and sensitive to neck blast. The elite indica restors such as 6326, Shuhui162 and Shuhui527 were bred with the resistant blast resources. Some topics on resistant rice blast breeding and making use of resistant cultivars logically were also discussed.
