Reproduction of Four Races of Meloidogyne incognita on Hibiscus cannabinus.
The feasibility of cultivation of kenaf (Hibiscus cannabinus) in the United States is receiving a multifaceted evaluation. Among the factors being evaluated is kenafs susceptibility to nematodes. In this investigation, four races of Meloidogyne incognita reproduced extensively on each of the several kenaf genotypes examined in greenhouse tests. Some genotypes of kenaf, however, demonstrated limited resistance to certain races of M. incognita.
