Ⅰ、前言迄今为止,同功酶作为遗传标志而应用于针叶树天然群体间及群体内的遗传变异调查,群体遗传构造、遗传分化以及交配方式等的报导很多(Lundkvist,1979;Plossas and Stra-us,1986) 。在纯株系的鉴定、采种源的判别、采种园花粉动态等育种应用研究方面,同功酶也被利用(Adams and Joly,1980) 。为判别遗传变异,同功酶作为遗传标志应用时,首先必须查明电泳取得的光带是受基因控制的,再用这种光带作为标志基因。为了进一步正
Ⅰ. Preface So far, isozymes as genetic markers have been widely used in genetic variability investigation, population genetic structure, genetic differentiation and mating methods among natural populations and among conifers (Lundkvist, 1979; Plossas and Stra-us , 1986). Isozymes are also used in the identification of pure lines, identification of provenance sources, pollen dynamics in seed collection fields, and the like (Adams and Joly, 1980). To determine the genetic variation, isozyme as a genetic marker application, we must first identify the electrophoresis band obtained by the gene control, and then use this light as a marker gene. In order to further positive
