Genetic behavior of characteristic of tolerance to photooxidation in rice was studied with the screening and identification techniques for tolerance to photooxidation, additive dominant genetic model and analysis methods. The results showed that the characteristic of tolerance to photooxidation in rice was inheritable and controlled by both additive and dominant effects. The additive effect functioned stronger with higher heritability. The identification and screening for characteristic of tolerance to photooxidation and execellent agronomic traits can be conducted in early hybridization generation and may abtain good selective effect and genetic progress. Based on the analysis of genetic effect from parents, 02428, Lemont, IR66158 37 and IR65600 86 were excellent parents with good tolerance to photooxidation and could be applied to rice physiological breeding for high photosynthetic efficiency.
