Abstract

The aim of the study is to assess Crotalaria ochroleuca susceptibility to six Heterodera glycines races. To this, C. ochroleuca seedlings and two soybean cultivars were transplanted and individually inoculated with nematode races 1, 2, 3, 5, 6 and 14. Plants were collected and assessed 30 and 60 days after inoculation. Crotalaria ochroleuca reduced the number of females and the total number of eggs of the races 1, 2, 5 and 6. The reproduction of race 3 in crotalaria was equal to that of soybean cultivars in both assessment periods, whereas race 14 only reduced the reproduction in crotalaria to 60 days. Races 1 and 6 (30th day) and races 6 and 14 (60th day) showed number of eggs female-1 smaller than the controls. According to female index (FI), C. ochroleuca was resistant to races 1, 2 and 5, susceptible to race 3, and showed varying reactions to races 6 and 14.
