Abstract

Evaluation on the resistance of kenaf accessions (Hibis¬ cus cannabinus /..) to Fusarium oxysporum Schlect

Resistant variety is one of the most important components controlling of fusarium wilt disease on kenaf caused by Fusarium oxysporum Schlect. To ind out resistant variety an evaluation on kenaf accessions was conducted in the laboratory and screen house of Phytopathology, RITFC, Malang in June-December 1997. The results of the selection on 77 accessions showed that 41 accessions were highly resistant, 1 2 accessions were resistant, 7 accessions were moderate, 12 accessions were susceptible, and 5 accessions were highly susceptible Three resistant and highly resistant accessions were namely 85-9-73, DS/005 H, and FJ/004 He could inhibit F. oxysporum growth about 23.40- 32.43 mm and its discolorisation about 0.0-13.4%.
