The results indicated :there were highly significant differences in 45 genotypes for all the root lodging resistance traits; the GCA was more important than the SCA in the genotypic variations for root resistance traits and the GCA differences were rather remarkable in the same trait of the various inbred and in the same inbred of the various traits; the positive genetic correlation.

Study on the Population Quality and Lodging Resistance of Hybrid Rice Jinyou527 in the High and Low Altitude Regions;

Based on theoretical analysis and physical simulated tests, the result showed that rice panicle typeaffected lodging resistance by bending moment (moment of making straw curved) and barycenter, the lodgingresistance decreased with the bending moment increaseing or barycenter lifting.

The difference of lodging resistance for nine japonica rice varieties from northern China with different panicle types was studied.

Application of the Grey Systematic Theory to integrated evaluation of lodging resistance in Oat;

Influence of single basal application controlled-release fertilizer on morphologic development of root system and lodging resistance of rice;

Mechanical evaluation and cause analysis of rice-stem lodging resistance under controlled irrigation in cold region

And the principle of the fiber lodging resistance was indicated.

The lodging resistance capability of five japonica hybrid rice combinations with higher stems and drooping panicles,including Tiyou 418,Liaoyou 5218,Liaoyou 2005,Liaoyou 2006 and Liaoyou 2016 was investigated under higher fertility conditions.

Lodging resistance capability of hybrid japonica rice Tiyou 418 and Liaoyou 5218 were investigated under higher fertility condition.
