    Abstract:

    The functional quality of weedy rice was studied using 41 representative weedy rice germplasms in Ningxia. The results showed that the contents of flavonoids, vitamin B1, vitamin B2, iron, zinc, and selenium in weedy rice were highly variable, and the coefficient of variation was more than 13%. The contents of flavonoids, vitamin B1 were lower than the selection.In contrast to the landraces and modern varieties,no significant difference iron, zinc, and selenium was observed in weedy rice, while the vitamin B2 was significantly higher. Through comprehensive analysis of functional quality traits, nine weedy rice accessions with elite traits were identified, and these resources might be useful in breeding for super-quality rice and broadening the rice gene pool in Ningxia.
