226个云南栽培稻品种进行酯酶同工酶分析,共获得11种酶谱类型。海拔由低到高变迁,酯酶同工酶酶谱类型由多至少变化。按地理分布,滇西南酶谱类型最丰富,滇东南次之滇西北最少。研究认为,原始栽培稻可能起源于海拔600—1400米、北纬25°以南的滇西南地区。研究结果证明云南是亚洲栽培稻起源中心之一。
226 cultivars of Yunnan cultivated esterase isozyme analysis, a total of 11 types of zymogram. Changes from low to high altitude, esterase zymogram type from at least changes. According to geographical distribution, the zymogram type is the most abundant in southwest Yunnan, and the least in Yunnan and southeast Yunnan. According to the study, the original cultivated rice may originate from southwestern Yunnan at an altitude of 600-1400 meters and south of latitude 25 degrees north latitude. The results show that Yunnan is one of the origins of cultivated rice in Asia.
