近年来国外在林木遗传育种研究中,对同工酶的研究日益增多,进展较快。在无性系鉴别(酒井宽一,1974),种子园的家系分析(Dag Rudin and Dag lindgren,1977),林木种内杂交及杂种后代的遗传分析(田岛正启,1977)等方面进行了广泛的研究。d.,H。I[oaoaoBA(1978)和Dag Rudin㈠976)对同工酶在林木遗传育种研究中的应用和展望作了评述。随着同工酶遗传基础研究的进一步深入,同工酶将成为林木遗传分析的一种有效手段。 两年来,我们用同工酶鉴定林木杂种,摸索同工酶与林木杂种优势的关系,试图预测林木杂种优势。现将部分试验结果报告如下。
In recent years, foreign countries in the study of tree genetics and breeding, the research on isoenzyme is increasing, rapid progress. A wide range of applications were made in clonal identification (Kawai et al., 1974), Dag Rudin and Dag Lindgren (1977), genetic analysis of interspecific hybrids and hybrid offspring (Tajima Masaki, 1977) Research. d., H. I [oaoaoBA (1978) and Dag Rudin (1976) reviewed the application and prospect of isozymes in the study of tree genetic breeding. With the further study of genetic basis of isozymes, isozymes will become an effective means of genetic analysis of trees. In the past two years, we used isozymes to identify tree hybrids and explored the relationship between isozymes and tree heterosis in an attempt to predict tree heterosis. Now part of the test results are reported below.
