| Abstract: | According to the analysis of the major traits of grain quality of indica hybrid rice combinations that have passed through the appraisals in Fujian in recent years, high chalkiness rate and degree, low gel consistency and high amylose content are the principal reasons for poor grain quality at present. The way of genetic improvement of grain quality is proposed. Grain quality traits are inheritable, there is a close relation between offspring and parents. Therefore, in order to achieve a fundamental improvement of grain quality of indica hybrid rice. It is necessary to pay more attention on A and R line selection of high grain quality. |
| Keywords: | indica hybrid rice chalkiness gel consistency amylose content genetic improvement |
