品种资源是育种的物质基础,是研究遗传、生理、生态、抗病等问题必不可少的材料。现将近五年来我们小麦品种资源研究工作简结如下: 一、目的及任务 1.品种种子保存,保持发芽力。 2.特征和特性的鉴定,包括生长习性、株高、成熟期、植物学性状以及抗病性等。 3.随时注意选拔在生产上有直接利用可能的品种,提供产量试验。 4.不断搜集国内外品种,增加新材料。 5.编制品种资源目录供有关单位参考。
Variety resources are the material basis for breeding and are indispensable materials for studying genetic, physiological, ecological, disease-resistant and other issues. Now nearly five years of our wheat resources research summary is as follows: First, the purpose and tasks 1. Variety of seeds to maintain and maintain germination. Identification of features and traits, including growth habit, plant height, maturity, botanical traits and disease resistance. 3. At any time to pay attention to selection in the production of direct use of possible varieties, to provide yield testing. 4. Continue to collect domestic and foreign varieties, add new materials. 5. The preparation of varieties of resources for reference for the relevant units.
