正确选择原始材料,即抗源品种,是小麦抗病育种成功的一个主要条件。但是,远不是所有有价值能抗性品种均具有经济上重要的特征特性。此外,众所周知,由于基因型的特点,这些参加杂交的品种是以不同情况把抗病性传递给后代的。有关品种免疫特性和供体特性的报导,对育种家挑选优良亲本会有重大的帮助。我们设想,选择作为抗性供体的品种需要考虑下列特性鉴定的资料:在2～3年研究过程中在田间条件下人工接种锈病病菌种群时选择品种抗性类型的稳定性;品种对该生态地区
The correct choice of the original material, that is, anti-source species, is a major condition for wheat disease-resistant breeding success. However, far from being economically important, all valuable resistant varieties are characteristic. In addition, it is known that due to the genotypes, these hybrids participate in the transmission of disease resistance to their offspring in different situations. Reports on the immune and donor properties of breeds will be of great help to breeders in selecting good parents. We hypothesize that the selection of cultivars as resistant donors requires the identification of the following characteristics: the stability of the type of resistant species selected for the artificial inoculation of the pathogen of the rust under field conditions during 2 to 3 years of study; area
