Description An aphid resistant groundnut (Arachis hypogaea) genotype, EC36892, introduced from ICRISAT Asia Centre in 1990, and 3 local cultivars were evaluated in China for resistance to aphids (Aphis craccivora) and peanut stunt cucumovirus (PStV) during 1991 and 1992. Aphid multiplication was much lower on EC36892 than on local cultivars in greenhouse tests, on average 0.6 vs. 6.9 aphids/plant on local variety Huohua 1. In field trials at Wuhan, EC36892 showed higher resistance to aphids in both years. In 1991, there were 4 aphids per 100 plants compared to 60 aphids on Hua 37 and 330 aphids on Huohua 1 at the first aphid multiplication peak. PStV incidence varied during the 2 years of field trials, but EC36892 had lower incidence than the local cultivars. In both years, EC36892 gave higher yields than Huohua 1 but lower than those of Hua 37 and Yihua 1.
