水稻酯酶同工酶的分析是研究稻作起源、演化与分类的最有效方法之一。本研究选用东南亚(含我国)与西、南亚各国几个主要稻种类型465个地方品种及普野(O.rufipogon)19份。1988年在北京对含有不同酶带的品种(编号)作杂交获18个组合 F_1代种子,1989年春在海南加代得 F_2代种子,1989年秋冬在北京对全部品种及其 F_1和 F_2代皆以单粒成熟种子进行酯酶 Rice esterase isozyme analysis is one of the most effective ways to study the origin, evolution and classification of rice. In this study, 465 indigenous rice varieties and 19 O.rufipogon cultivars from Southeast Asia (including China) and Western and South Asian countries were selected. In 1988, 18 combinations of F_1 seeds were obtained from crosses of cultivars containing different enzyme bands in Beijing. In the spring of 1989, F_2 and F_2 seeds were added in Hainan Province. In autumn and winter of 1989, all cultivars and their F_1 and F_2 generations were Single grain mature esterase
