1) Artificial selection
人工选择
1.
Through analysing the orientation and results between natural selection and artificial selection, this paper indicated that both selections result in competition for the existence of the natural population, and in improving economic yield of the artificial population, respectively, and orientations of both selections are colony superority for artifical popula tion, and individual supe.
从分析自然选择和人工选择在目标和方向上的重大差异入手，指出自然选择的核心是生存竞争，其结果产生个体优势；人工选择的方向是群体优势，其目标是获得较高的经济产量。

To detect response of main-effect QTL(M-QTL) in mapping populations to artificial selection,stably expressed M-QTL was identified from backcross inbred lines in Teqing background(TQ-BIL) in Beijing and Hainan.
利用粳稻Lemont导入籼稻特青背景构建的高代回交导入系和重组自交系群体,在北京和海南两地检测影响株高和剑叶宽的稳定表达的主效QTL,分析这些主效QTL在导入系和重组自交系群体的不同选择强度(5%、10%和20%)的极端群体中的等位基因偏离,研究不同性状的主效QTL对不同选择强度的响应及不同遗传结构群体对主效QTL人工选择响应的影响。

补充资料：人工选择
人类对自然界出现的生物变异进行无意识或有目的的选择，形成生物新类型的过程。达尔文认为，饲养动物和栽培植物是长期人工选择的结果。现已成为选育农作物和家畜家禽优良品种的重要手段。
