一、前言酶分子是基因表达的最终产物,利用它的某些特征可以进行遗传和育种上的研究.酯酶同工酶由于具有作物品种间的相对稳定性,多年来在国内外被用于多种作物品种资源分析考查;杂交优势的成因和预测;遗传基因定位;雄性不育机理研究等方面,并取得了许多结果.中川原正弘(1975)、林健一(1975)、周光宇(1979)、朱英国(1982) 等先后用酯酶同工酶作为遗传的生化指标对许多国家和地区水稻品种资源开展研究,提出了栽培稻起源地及品种之间的亲缘关系.易琼华(1981) 等研究了酯酶同工酶酶谱与水稻杂种优势的相关性,指出利用互补酶带作为杂种优势预测
I. INTRODUCTION Enzyme molecule is the final product of gene expression and can be used for genetic and breeding research with some of its characteristics.Esterase isozymes have been used both at home and abroad for many years due to their relative stability among crop varieties Zhongyuan Yu (1975), Lin Jianyi (1975), Zhou Guangyu (1979), Zhong Guangyu (1975) , Zhu Ying-guo (1982) successively used esterase isoenzyme as the genetic biochemical indicator to study the rice variety resources in many countries and regions, and put forward the genetic relationship between cultivated rice origin and cultivars. Yi Qionghua (1981) Et al. Studied the correlation between esterase isoenzyme patterns and heterosis in rice, and pointed out the use of complementary enzyme bands as a predictor of heterosis
