Field evaluation of germplasm of Hibiscus cannabinus L. against foot and stem rot caused by Phytophthora parasitica Dast and collar rot caused by Sclerotium rolfsii Sacc.

摘要

In studies conducted in India, 40 kenaf lines were screened against foot and stem rot disease caused by P. parasitica [P. nicotianae var. parasitica] and collar rot caused by S. [Corticium] rolfsii over 3 successive years. Lines were more susceptible to Corticium than Phytophthora, and none were immune to Phytophthora or Corticium. Thirty three lines were highly resistant, 6 resistant and 1 strain was moderately resistant to Phytophthora. Fourteen strains were resistant, 19 moderately resistant and7 strains, moderately susceptible to Corticium.
