摘要

Abstract

The receptor cultivar Nan29 and thirty-six T5 rice lines derived from ten T0 generation transgen-ic plants harboring lysozyme gene were challenged in the greenhouse by inoculating 63 isolates belonging to 48races of Magnaporthe grisea from Yunnan Province. The transgenic rice lines exhibited resistance to morethan 72% of isolates inoculated in this experiment, and 38.1% (24 isolates) of them could infect the receptorcultivar Nan29. The results indicated that the transgenic rice lines possessed wide-spectrum resistance againstvarious rice blast races and the resistant spectrum of rice lines were different although some lines derived fromsame T0 plant. The transgenic rice lines exhibited also high resistance to leaf and neck blast in the disease fieldevaluation, but not all of resistant lines against leaf blast were resistant to neck blast.
