亲本系数 (COP)是常用的度量遗传多样性的指标之一 ,但采用亲本系数法得出的遗传多样性与作物产量间的关系呈现出不一致的结论。在总结国内外研究方法的基础上 ,提出了遗传单一性这一新的多样性分析指标。结果表明 ,遗传单一性与小麦产量间存在着显著的负相关 ,并对其政策含义进行了讨论。
The parental coefficient (COP) is one of the most commonly used indicators for measuring genetic diversity, but the relationship between genetic diversity and crop yields using the parental coefficient method shows inconsistent conclusions. On the basis of summarizing the research methods at home and abroad, this new diversity analysis index of genetic unity is proposed. The results showed that there was a significant negative correlation between genetic unity and wheat yield, and its policy implications were discussed.
