There were 11 zymogram types of esterase isozyme in these cultivars When height above sea level increased, the zymogram type number decreased. According to geographical position, zymogram type number of esterase isozyme occupied first place in south—west Yunnan, and that come second in south—east Yunnan, but it was the last in north—west Yunnan. T e result showed it was possible that primary cultivated rice originated from south—west Yun-nan, in an elevation of 600—1400 m and below 25 degrees north latiude. The result proved that Yunnan was one of centers from which Asian cultivated rice originated. Evolution of zymogram was analysed and discussed, 1984-01-01 2021-04-01 1
