Identification of Soybean Varieties for Resistance to Soybean Cyst Nematode Races 14
Soybean cyst nematode is one of the most devastating pests of soybean,it could cause extensive economic losses in China and worldwide.Resistant soybean varieties are the most effective method available for management of SCN.The objectives of the study were to screen sources of resistance to SCN and determine the characteristics of the resistance.167 accessions of soybean varieties (lines)were evaluated for the resistance to the race 14 of soybean cyst nematode.The results showed that,3 soybean varieties were high resistant,accounting for 1.8％ of the total evaluated cultivars,20 varieties were moderate resistant,accounting for 11.98％ of the total.The 23 germplasms were all resistant to race 14 of SCN by pot experiment.Most of the 167 tested germplasms were susceptible or highly susceptible to race 14 of SCN,and the resistant germplasms were Xiaoheidou and its progeny.The resistant varieties and germplasm resources identified in this study could provide material platform for breeding of soybean cyst nematode.It is significant on developing resistant resources for main production area of northeast soybean and production of soybean the whole country.
