前人对稻米品质性状的研究,是在碾磨品质,米粒大小与形状,胚乳性质,蒸煮和食用品质及营养价值等方面研究较多,而对稻米色素的遗传研究较少。国内外虽有过一些报道,但由于供试材料遗传结构的差异,试验结果很不一致。到目前为止,人们对水稻色素的遗传规律还是知道不多的。黑(紫)稻是一种特殊的品质资源。其颖壳或籽粒种皮由于具有黑(紫)色素而呈现黑(紫)色。颖壳和种皮的色素属于质量性状,受基因控制,能够遗传。黑(紫)米含有丰富
Previous researches on quality traits of rice have been studied more and more in the aspects of milling quality, grain size and shape, endosperm properties, cooking and eating qualities and nutritional value, and few researches on the inheritance of rice pigment. Although there have been some reports at home and abroad, due to the differences in the genetic structure of the tested materials, the test results are very inconsistent. So far, the genetic laws of rice pigment still do not know much. Black (purple) rice is a special quality resources. Its husk or seed coat shows black (purple) color due to its black (purple) pigment. The pigments of glume shell and seed coat belong to quality trait, controlled by gene and can be inherited. Black (purple) rice is rich
