Abstract

The objective of this study was the characterization of commercial cultivars, differentiating lines/cultivars of Phytophthora sojae carrying Rps (resistance Phytophthora Sojae) genes, inoculated with different pathotypes. Thirty-one differentiating soybeans (Glycine max (L.) Merrill) lines/cultivars carrying Rps genes and six commercial cultivars were evaluated for virulence pattern to PS2.4, PS14.4, PS36.1, PS34.1, and CMES1608 pathotypes. Inoculations were performed using the toothpick technique, with reaction evaluation about 15 days after infection, where the number of healthy, infected, and dead seedlings was quantified. There was a difference in resistance for the pathotypes, and the most virulent were PS34.1 and PS36.1. The Rps1k, Rps11, and Rp12 genes deserve to be highlighted by resistance to the PS34.1 pathotype and the Rps1k, Rps11, Rp12, and Rps8 genes to the PS36.1 pathotype. The line L77-1863 (Rps1b) showed resistance to the PS2.4 and PS14.4 pathotypes. The characterization of the genotypes allowed the updating of information about them and the identification of new possibilities of resistance sources.

大豆疫霉分化系的鉴定

本研究的目的是对接种不同致病型的大豆疫霉（Phytophthora sojae）抗性基因（Rps）的商品品种、分化系/品种进行鉴定。三十一分化大豆（Glycine max (L.)）对携带Rps基因的美林（Merrill）系/品种和6个商品品种对PS2.4、PS14.4、PS36.1、PS34.1和CMES1608病型的毒力模式进行了评价。使用牙签技术接种，在感染后约15天进行反应评估，量化健康、感染和死亡幼苗的数量。不同病原菌的抗性存在差异，其中PS34.1和PS36.1的抗性最强。Rps1k、Rps11和Rp12基因对PS34.1病型的抗性以及Rps1k、Rps11、Rp12和Rps8基因对PS36.1病型的抗性值得强调。L77‐1863 （Rps1b）显示出对PS2.4和PS14.4病型的抗性。基因型的鉴定使有关它们的信息得以更新，并确定新的耐药来源的可能性。
