甜菜品种资源是指本地区的地方品种(农家品种、改良品种)、外地区和国外的引进品种、野生种属和人工创造或自然形成的变异类型材料。甜菜育种,是在广泛搜集、妥善保存品种资源,并加以深入鉴定研究、充分认识和发掘各种遗传基因资源的前提下,通过变异、基因重组、定向培育、定向选择、生殖隔离、后代鉴定等过程,从中选育出适应当地甜菜生产和制糖工业发展需要的新品种。因此,甜菜品种资源是甜菜育种工作不可缺少的物质基础。另外,对搜集到的品种资源,经过在本地区观察试种和生产试验,证明它能比当地推广品种增产,就可直接在生产上推广利用。显而易见,搞好甜菜品种资源工作,既能够不断为育种提供丰富多彩的遗传基因资源,又能够鉴定出一些优良品种直接为生产服务。
Beet varieties resources refer to local varieties (farm breeds, improved breeds) in the region, imported breeds in the region and abroad, wild species, and types of materials that are artificially created or naturally formed. Beet breeding is based on extensive collection and proper preservation of variety resources, in-depth identification studies and full understanding and exploration of various genetic resources. By means of mutation, gene recombination, targeted cultivation, targeted selection, reproductive isolation and identification of offspring Process, from which bred to adapt to the local sugar beet production and sugar industry needs new varieties. Therefore, beet variety resources is an indispensable material basis for beet breeding. In addition, the collected varieties of resources, through the trial observation and production trials in the region to prove that it can promote more varieties than the local production, you can directly promote the use of production. Obviously, doing a good job of beet variety resources, not only can provide rich and colorful genetic resources for breeding, but also can identify some good varieties directly for the production of services.
