Race Distribution of Soybean Cyst Nematode in the Main Soybean Producing Area of Huang-Huai Rivers Valley
摘要
Abstract
Soybean cyst nematode (SCN) disease, caused byHeterodera glycines, occurs widely in the Huang-Huai Rivers Valley. Resistant cultivar is the most important solution to ocntrol this disease and reduce yield loss. Knowledge of SCN race distribution in soybean producing area is basis for SCN resistant breeding. A four-year survey from 2012 to 2015 was carried out to under-stand the diversity and distribution ofHeterodera glycines races in the Huang-Huai Rivers Valley. A distribution map of races was constructed based on Riggs model. A total of 322 soil samples with SCN infection were collected. Seven H. glycines races were identified in 112 (34.8%) samples from six provinces, including five races described previously. Race 2 was the leading race, ac-counting for 50.9% in the 112 soil samples; race 5 was next to race 2 with the ratio of 23.2%; and the remaining types were races 4, 3, 1, 6, and 11, accounting for 9.8%, 5.4%, 4.5%, 4.5%, and 1.8%, respectively. The distribution of races varied greatly among the six provinces. According to frequencies from high to low, they were races 5, 2, 3, and 11 in Henan, races 2, 5, 6, 3, and 4 in Hebei, races 2, 5, 6, and 3 in Anhui, races 2, 4, 5, 1, 3, and 11 in Shanxi, races 2, 3, 5, 1, and 6 in Shandong, and races 2, 5, and 1 in Jiangsu. These results indicate that race 2 is the predominant race in the Huang-Huai Rivers Valley, followed by race 5, and the most virulent race 4 is centered in Shanxi province. Therefore, the SCN resistant breeding in this region should be mainly targeted towards race 2 with consideration of race 5 simultaneously, and race 4 also needs attention in some areas. In this study, races 3, 6, and 11 were newly detected in the Huang-Huai Rivers Valley. We also found that the race components and their distributions var-ied compared to the survey conducted in the same region in 2001–2003.关键词
