Zou Detang, Qiu Taiquan, Zhao Hongwei, Cui Chenghuan (Department of Genetics and Breeding, Northeast Agricultural University, Harbin, 150030 PRC)  
The results of this study showed tlat the characters of the basal setback weight, photosynthetic rate and biological yield had negative effects on the lodging index of rice, but tte plant weight and fresh weight had the positive effects Among the characters mentioned above, the basal setback weight played leading direct roles It was proposed that the selection of higher basal setback weight, photosynthetic rate and biological yield was benificial to the breeding of rice varieties with high lodging resistance and yield
