本文作者认为,影响褐斑粒形成和发展的诸因素中,大豆种质起决定性作用。播种期和毒株对褐斑粒的形成和种皮斑驳发展的影响,视不同品种而异。有些抗斑驳型品种,受播种期和毒株的影响不大。在感斑驳型的品种中,感染时期对褐斑粒形成也有一定影响:花期感染,引起褐斑粒最重;荚期以后感染,褐斑粒明显下降。研究指出,筛选抗斑驳型的种质,作为抗病育种的抗原应用,对降低褐斑粒的严重度,提高大豆品质,是完全可能的。
The author believes that the factors that affect the formation and development of brown spot, soybean germplasm play a decisive role. The effects of sowing date and strain on the formation of brown speckles and the development of seed coat mottle vary depending on the breed. Some anti-mottled varieties, by the sowing period and strains little effect. In the variegated variety, the period of infection also had a certain impact on the formation of brown speckles: florescence infection caused the heaviest brown spot; pod infected later, brown spot decreased significantly. Research shows that screening anti-mottled germplasm, as a disease-resistant breeding antigen application, to reduce the severity of brown spot, improve the quality of soy is entirely possible.
