Theoretical Analysis and Simulated Determination on the Relationship between Rice Erect Panicle Type and Lodging Resistance

DU Xing-lin, FANG Xiu-qin, et al.(Rice Institute, Academy of Agricultural Sciences of Jilin Province, Gongzhuling, 136100, China)  
Shennong 265, a super-rice with erect heavy panicle bred by Shenyang Agricultural University, was selected as trial variety. Over 20 mid-length panicles with typical erect panicle were chosen and cut at the base of stem and their gravity and curved power measured in medium late period of fruiting. The results showed that panicle type influences lodging resistance by curved force and gravity. In northern China, lodging of Japonica rice generally follows the order as follows: at first from panicle to panicle-neck and upper internode, then the plant appears to curve and lodge gradually. The curve of panicle can be seen as the beginning of lodging to some extent.
