采用具有代表性的41份杂草稻种质材料,开展宁夏杂草稻稻米功能型品质的研究。结果表明,杂草稻的黄酮、维生素B1、维生素B2以及铁、锌、硒含量存在较大变异,变异系数均达13%以上;杂草稻的黄酮、维生素B1含量低于选育品种,铁、锌、硒元素含量与选育品种相似,杂草稻的维生素B2(0.032 mg/100g)含量总体高于地方品种(0.026 mg/100g)和选育品种(0.027 mg/100g)。通过功能型品质性状综合分析,筛选出了9份优异杂草稻资源,为改善宁夏水稻品质,拓宽宁夏水稻遗传基础奠定基础。
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.
