中国古书中记载的野生稻除部分为栽培稻自生误记外,一般均非稻属(Oryza L.)植物,而是稗属(Echinochloa L.)和菰属(Zizania L.)等禾本科植物。特别是菰属中的野茭白米,中外都有称为野生稻米的。江苏连云港(禾鲁)稻的特征特性与地方品种有很多相似处,似与地方品种相互杂交分离的后代。由于古书中所载野生稻与江苏连云港稻都不是现今科学鉴定的野生稻类型,因此有些学者以此为据论证长江中下游为粳稻起源地,似亦不可能成立。 Wild rice, which is recorded in ancient Chinese books, is generally classified as non-Oryza sativa (Oryza sativa L.) except for some self-inflicted rice cultivars, but rather grass plants such as Echinochloa L. and Zizania L. . In particular, wild goose is a wild white rice, both at home and abroad are called wild rice. Jiangsu Lianyungang (Wo Lu) characteristics and characteristics of rice and local varieties have many similarities, it seems that hybrids with local varieties cross offspring. Since the ancient books contain wild rice and Jiangsu Lianyungang rice are not the type of scientific identification of wild rice, some scholars use this as evidence that the Yangtze River as the origin of japonica rice, it seems unlikely to be established.
