【Abstract】 The generations of pressure induced rice mutant lines, Yueya No.1, Yueya No.2, and Yueya No.3 were bred from Yuexiangzhan,a new rice variety with high harvest index,and the agronomic traits were compared between the generations and Yuexiangzhan. Results showed obvious differences between the generations and Yuexiangzhan in duration, plant height, tillering number, effective panicle number, filled grain rate, grain quality, resistance to diseases and coldness. It indicated that the technique of high pressure inducing variation may be a new method for plant breeding.更多还原
