Analysis on population genetic variation and its correlation to heterosis of body weight using microsatellite dna markers in yellow plumage broilers 黄羽肉鸡群体遗传变异的微卫星分析及其与体重杂种优势的关系
For crop plants , hybrids vigor is particularly important for characteristics such as growth rate , yield , and disease resistance 对于农作物而言，杂种优势在生长速度，产量和抗病能力等方面表现出更显著的优越性。
Population genetic structure was studied using rapd analysis to reveal the relationship between the genetic variations and heterosis 同时采用rapd技术对f1代不同群体的遗传结构进行比较，研究群体内的遗传变异与杂种优势的关系。
It has been proved that morphological improvement combined with utilization of heterosis is one of the most important ways to raise rice yield ceiling genetically 摘要理想株型与杂种优势利用相结合是实现水稻单产突破的重要途径之一。
The kinds of molecular markers were summarized , and their mechanism as well as characteristics about some related to heterotic research were analyzed too 摘要概述了分子标记的种类，分析了杂种优势研究中常用的几种分子标记的原理、特点。
Usually the more unlike the parents are the more hybrid vigor is released , but the effect diminishes in subsequent generations as more recessive homozygotes reappear 通常，亲本越不相似，产生的杂种优势越强，但这种优势使下一代的隐性纯合子的出现机率更多。
Much attention , for which , has been paid to the research of male sterility mechanism and its application in it inthe past several decades 白菜杂种优势十分明显，其雄性不育系利用一直被认为是目前一代杂种生产的理想途径，因而，有关其雄性不育发生的机理研究一直深受人们的重视。
