Abstract: In order to explore soybean germplasm resources resistant to Phytophthora root rot in northern region of Heilongjiang province, 113 soybean varieties and breeding materials were identified by wound inoculation on soybean hypocotyl. The result showed that seven soybean resistant germplasms were screened, accounting for 6.19% of the total identified soybean, and five medium resistance germplasms were obtained, accounting for 4.42% of the total identified soybean. Among them, one resistant germplasms and one medium resistant germplasms were identified from the third accumulated temperature zone varieties. Three resistant resources and two medium resistant germplasms were obtained from the fourth accumulated temperature zone varieties. One resistant germplasm and two medium resistant germplasms were screened from the fifth accumulated temperature zone varieties. Two resistant resources were identified from the sixth accumulated temperature zone varieties, but no medium resistant germplasms were found. Therefore, resistant germplasms were already obtained from different accumulated temperature zones. The results provide a reference for the breeding and utilization of soybean germplasm with resistance to Phytophthora root rot in northern Heilongjiang.
