植物的选种方法很多,有有性系选种(实生选种)和无性系选种(营养系选种)及其现代新技术选种等。植物的芽变选种,是一种古老的选种方法,属植物无性系选种的范畴,即是对植物自然发生的优良芽变,进行人工选择,定向培育,使植物的品种不断丰富和提高,从而更好地为人类服务。一、芽变的前提——遗传和变异遗传和变异是生命进化过程中的一对矛盾的两个方面,其中遗传是相对的,变异是绝对的,它们是生物界普遍存在的规律,是一切生物共有的特性。现代遗传学阐明: Plant selection methods are many, there are sexual line selection (seed selection) and clonal selection (nutrition selection) and its selection of new modern technologies. Plant mutation selection, is an ancient method of selection, is a category of clonal selection of plants, that is, the natural occurrence of plant buds, artificial selection, directional cultivation, the plant species continue to enrich and Improve, so as to better serve humanity. First, the premise of bud change - Genetic and mutation Genetic and mutation is a pair of contradictions in the process of evolution of life two aspects, of which the genetic relative, the mutation is absolute, they are the universal law of the biological world, is everything Biologically common characteristics. Modern Genetics states:
