选用中国7省571份,国外27份普通野生稻(Oryza rufipogon Griff简称普野)的10个形态性状进行了聚类分析并结合普野栖生地的生态考察,将中国普通野生稻划分为多年生与一年生两个普野群,七个普野型。作者根据普野植株在北京温室越冬与翌春植株再生情况及其繁殖方式并联系其生长习性与同工酶分析论证了,中国除多年生普野外还存在一年生普野,但其野生自然群体尚待考察与研究确认。本文还对中国栽培稻的原始型祖先种普野的形态、生态、酯酶同工酶谱型及其群体特点进行了讨论。
A total of 571 Chinese 7 provinces and 27 wild Oryza rufipogon Griff (Oryza rufipogon Griff, abbreviated as Puye) were selected for cluster analysis and ecological survey of common wild habitats. The common wild rice in China was divided into perennial Two annual wild group, seven general wild type. The author according to Pu wild plants in Beijing greenhouses and wintering next spring, plant regeneration and reproductive patterns and their growth habits and isozymes analysis of correlation demonstrated that, in addition to perennial universal wild there are annual common, but its wild natural groups yet to be Study and research confirmed. The paper also discussed the morphological, ecological, esterase isoenzyme patterns and their population characteristics of primitive wild ancestors of cultivated rice in China.
