云南省地处西南边陲,境内地形复杂,海拔高低悬殊,气候差异很大,形成了类型繁多并具有耐寒、耐旱、抗病虫、大穗、大粒、米质好等性状优异的云南高原稻种,为国内外育种工作者所重视.但由于株型高大,外地引种易倒伏,难以利用.为此,将云南稻在南京种植,研究其植株形态变异的规律,以期在育种上利用. Yunnan Province is located in the southwestern border, the territory of the complex terrain, high and low altitude disparity, climate is very large, forming a variety of and has cold, drought, pest resistance, big spike, big grain, good quality rice and other characteristics of the Yunnan plateau rice However, due to the tall plant type, it is hard to utilize due to the introduction of plants in other areas.Therefore, Yunnan rice is planted in Nanjing, and its regularity of plant morphological variation is studied in order to utilize it in breeding.
