    Abstract:

    This study reported the evaluation of the grain quality traits of rice landraces that were collected from "The Third National Action on Crop Germplasm Resources Survey and Collection" in 2017-2021. Out of 165 white and red grain samples, the highest variation coefficient was observed on the chalkiness of sticky rice, of which the coefficient of indica white grain was as high as 148.91%. The transparency was also detected with high variation coefficient, while the coefficient of brownish was below 5.0%. The variation coefficient of the waxy ratio amongst waxy rice was over 70.0%, the whiteness and the amylose content have lower value of the variation coefficient, while that of the three indexes including brownish, alkali elimination value and gel consistency were below 10.0%. In terms of the grain quality indexes that reaching the standard, the qualified ratio of whole grains or their chalkiness of sticky rice were below 50%, while the qualified ratio of other indexes were above 65.0%. For the glutinous rice, the qualified ratio of whole grains and the amylose content were around 50.0%, and that of the other indexes was higher than 65.0%. The cooking and edible quality is an important aspect in evaluating high-quality rice as well. Among all the varieties of sticky rice and glutinous rice, 60.7% and 35.4%, respectively, of which have reached or above the Grade 3 level issued by the Ministry of Agriculture and Rural Affairs on the three indexes of cooking and edible quality. Compared with the landraces that were collected during the second national survey in Fujian, the amount of landraces with high value of cooking and edible quality has increased significantly within the third survey. Through this study, 10 landraces were identified reaching the high-quality standard issued by the Ministry of Agriculture and Rural Affairs, which provide a material basis for the development of high-quality rice varieties in the future. In addition, 15 germplasms with high amylose content have been identified, which can be used as new raw materials for processing purpose specifically. The mid-colored rice were found with relatively rich amount in local landraces, accounting for about 20.0% of the total, they can provide valuable resources for future breeding and production of rice varieties with special function. In the future, works on the evaluation of grain quality for local landraces should be improved, and excellent germplasm resources would provide a material basis as well as promote the breeding of new superior rice varieties.
