    选拔是生物演化(天然选拔)及动植物改良(人为选拔)的有效工具.生态环境的多元化差异、遗传基因的多样性、基因的不同变异方式以及与环境的互作是玉米育种的遗传学基础.本文依据多年形成的选系理论,对选系实践经验加以探讨.

    Selection is an effective tool for evolution (natural selection) and animal - plant improvement(artificial selection).The foundation for selection is based on clear diversity of natural environment, genetic variation or poly-morphism of genes and genetic-environment interaction.The basic theory and certain practical methods in selection were discussed.
