Improving rice high-quality potential is to suffice the food demand of the rapid decreasing consumption, and is a major breeding target recently. We calculated the alkali digestion value (ADV), used to indirectly measure gelatinization temperature, to evaluate the quality of cooked rice in 2013 and 2014. The ADV score of frequency distribution was higher milled rice than brown rice. In total, nine different quantitative trait loci (QTLs) were found on chromosomes1, 3, 5, 6 and 8 in 2013 and 2014. Also, chromosome 5, 8 were detected over two years. The polymorphism using RM223, RM3530, and RM18130 markers can be used to select lines that have a good trait for breeding of high-quality rice. We conclude that selected molecular markers from this QTL analysis could be exploited in future rice quality.
