There are 13 three lines indica hybrid rice combinations derived from chuanxiang 29A and registered in sichuan province. In the paper, the main quality traits of the 13 combinations and the relevant relations were analyzed. The results showed that the average milled rice rate is 58.5%, and 12 combinations achieved the national standard good quality rice grade three. The average length-width ratio is 2.8, and 5 combinations achieved the national standard good quality rice grade three. The average chalky grain rate is 38.2%, and 7 combinations achieved the national standard good quality rice grade three. The average chalkiness is 7.6%, and 6 combinations achieved the national standard good quality rice grade three. The average gel consistency is 63 mm, and 11 combinations achieved the national standard good quality rice grade three. The average amylose content is 22.4%, and 9 combinations achieved the national standard good quality rice grade three. The integrated rice quality of only 3 combinations in 13 combinations achieved the national standard good quality rice grade three. The main restricting factor are the length-width ratio, chalky grain rate and chalkiness. Among the various quality indicators, length-width ratio has a significant negative correlation with chalky grain rate and chalkiness. Chalky grain rate has a significant positive correlation with chalkiness. Milled rice rate has a significant positive correlation with chalkiness. Amylose content has a significant positive correlation with chalky grain rate and chalkiness. Therefore, to further enhance the quality of rice combinations derived from Chuanxiang 29A should focus on the choice of recovery lines with slender grain type, lower chalky grain rate and chalkiness.
