“…Since P. sojae was first discovered and isolated in Northeastern China in 1989 [ 21 ], many scholars have devoted themselves to the screening of germplasm resources for resistance to P. sojae and have confirmed the existence of abundant germplasm resources for resistance and concurrent resistance in China [ 27 , 28 , 29 , 30 , 31 , 32 ]. In the present study, 12 P. sojae strains were used to identify 112 short-season soybean cultivars from Northeast China for their resistance to PRR.…”

“…Northeastern provinces, including Heilongjiang, Inner Mongolia, Liaoning, and Jilin, are the main regions of soybean cultivation, accounting for up to 50% of the total cultivated area and yield of soybean in China, where most of the short-season soybean is grown. Since PRR was first reported in Heilongjiang Province in 1989 [ 21 ], it has become a major disease in most soybean-producing regions in China [ 22 , 23 , 24 , 25 , 26 , 27 ]. The virulence structure of P. sojae is complex, with different dominant virulence types of P. sojae in different regions [ 23 ].…”

Phytophthora root and stem rot caused by Phytophthora sojae Kaufmann and Gerdemann is a soil-borne disease severely affecting soybean production worldwide. Losses caused by P. sojae can be controlled by both major genes and quantitative trait locus. Here, we tested 112 short-season soybean cultivars from Northeast China for resistance to P. sojae. A total of 58 germplasms were resistant to 7–11 P. sojae strains. Among these, Mengdou 28 and Kejiao 10-262 may harbor either Rps3a or multiple Rps genes conferring resistance to P. sojae. The remaining 110 germplasms produced 91 reaction types and may contain new resistance genes or gene combinations. Partial resistance evaluation using the inoculum layer method revealed that 34 soybean germplasms had high partial resistance, with a mean disease index lower than 30. Combining the results of resistance and partial resistance analyses, we identified 35 excellent germplasm resources as potential elite materials for resistance and tolerance in future breeding programs. In addition, we compared the radicle inoculation method with the inoculum layer method to screen for partial resistance to P. sojae. Our results demonstrate that the radicle inoculation method could potentially replace the inoculum layer method to identify partial resistance against P. sojae, and further verification with larger samples is required in the future.

Cultivated soybean (Glycine max) is a fabaceous staple crop grown extensively for its forage and oil properties (Anderson et al., 2019).The soybean seed contains all essential amino acids required for human consumption, is enriched with macro-and micronutrients and provides an environmentally friendly protein source for both humans and monogastric livestock operations (Messina, 1999;Michelfelder, 2009). Furthermore, soybean oil contains high levels of unsaturated omega-3, omega-6 and omega-9 fatty acids (Anderson et al., 2019). During the 2017/2018 market year, worldwide soybean production exceeded 346 million tonnes, reflecting a growth of 350% since 1987 (Soybean Meal Info Center, 2018). Over 90% of such production is attributed to five countries: the United States, Brazil, Argentina, China and India (Pagano & Miransari, 2016). In the United States, the soybean sector generates approximately $115 billion (>0.7% of the gross domestic product) and employs 350,000 individuals with a total wage impact exceeding $11.6 billion (United Soybean Board and National Oilseed Processors Association, 2020). For these reasons, local, national and international breeding efforts are placed on economic yield increase and on the enhancement of soybean agronomic characters. Soybean yield and quality are influenced considerably by interactions with microorganisms. Most notably, soybean engages in nitrogen fixation with bacteria within the genera Bradyrhizobium and Sinorhizobium. These mutualistic symbioses culminate in 50% of the

Phytophthora root and stem rot (PRR) of soybean (Glycine max) caused by Phytophthora sojae is a serious disease that affects soybean production, causing a global economic loss of approximately $1-2 billion every year (Tyler, 2007). P. sojae is a typical soilborne oomycete pathogen with oospores that survive in the soil for several years. When conditions are favourable, oospores germinate to produce sporangia that release the core infection structures, zoospores (Schmitthenner, 1985). P. sojae can infect soybean at any growth stage, resulting in seed, root and stem rot and plant death (Schmitthenner, 1985). The rational use of soybean resistance is the most economical and effective means to control PRR (Zhang et al., 2013).The relationship between host soybean and P. sojae conforms to the gene-for-gene model, in which the proteins of Rps genes in soybean recognize those encoded by the corresponding Avr genes in P. sojae, which determines the resistance of soybean against P. sojae (Schmitthenner, 1985). More than 28 genes involved in resistance against P. sojae have been reported in soybean plants (Zhang et al.,
