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 biological evolution (natural selection) and animal and plant improvement (artificial selection). Diversification of ecological diversity, genetic diversity, genetic variation and interaction with the environment is the genetic basis of maize breeding. This article is based on years of formation of the theory of the election system, to explore the practical experience of the election system.
