赤霉病在我国小麦病害中的危害性仅次于条锈病,居第二位。它是长江中下游及华南冬麦区和东北春麦区东部最严重的病害。抗赤霉病育种已取得了一定进展,但其抗性尚未得到显著提高,更没有和高产基因型相结合。对于这样数量遗传的、遗传力低的、涉及多种性状的问题,沿袭传统的育种途径是难以解决的。建拓抗赤霉病的基因库应该是最适宜的对策。这种基因库是利用太谷显性雄性不育核基因,通过多亲本综合杂交和表型混合选择与后代测定选择相结合的轮回选择来建拓的。在任何轮选周期可将不同的新资源导入基因库使之继续得到开拓,而基因库中的各种优良基因型也可陆续提取以发展为新良种。此项工作的顺利开展有赖于参加单位间、小麦育种与植物病理工作者间的紧密协作。 Fusarium head blight in wheat diseases in our country is second only to stripe rust, ranking second place. It is the most serious disease in the middle and lower reaches of the Yangtze River, winter wheat in South China and eastern Chunbian in Northeast. Some progress has been made in the breeding of Fusarium head blight, but its resistance has not yet been significantly improved, nor has it been combined with high-yielding genotypes. For such a number of genetic, low heritability, involving a variety of traits, follow the traditional breeding methods is difficult to solve. Constructing the gene pool resistant to Fusarium head blight should be the most appropriate countermeasure. This gene bank was developed using Taigu dominant male sterility nuclear genes by multiple rounds of hybridization and phenotypic mixed selection combined with alternative selection of offspring. In any rotation cycle, different new resources can be introduced into the gene pool to continue to be exploited, and various excellent genotypes in the gene pool can also be successively extracted to develop into new breeds. The smooth progress of this work depends on the close cooperation among participating units, wheat breeding and plant pathology workers.
