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

The effect of tobacco curl disease on the yield and quality of eight Virginia tobacco varietiesTobacco leaf curl disease is one of the important diseases on Virginia tobacco which especially occurs in dry condition. The use of resistant varieties is one of the most effective way to control the disease. This experiment was lo evaluate the effect of tobacco curl disease on tobacco varieties (DB 101, Coker 319, Coker 176, Coker 48, Coker 86, and Coker 371 Gold) and two promising lines (T.45/T.65 and T.45/T.69). The experiment was conducted in Pekuwon, Sumberrejo, Bojonegoro from April to October 1997. The experiment was arranged in randomized block design with three replications. The tobacco seedlings wee transplanted in 0.9 m x 0.6 m spacing and 9.0 m x 9.0 m plot size. The fertilizer dosage applied are 300 kg ZA + 108 kg SP-36 + 156 kg ZK per ha The parameters observed including percentage of diseased plant, productive leaves, as well as the yield and quality of leaves. The esults showed that Coker 371 Gold variety showed the lowest disease percentage (6.89%), decrease in productive leaves was high (71.86%), Whereas the two promising lines, were T.45/T.6S and T.45/T.69 showed that the percentage of diseased plants wee not significantly different compared with DB 101, Coker 319, and Coker 48, but the decrease in productive leaves was lower. The yield of these promising lines were 10.12-10.30 kg/81 m!, grade indexes 86.04-87.27, and crop indexes are 88.31-88.63. Coker 176 was the most susceptible variety. The percentage of diseased plant, flue- cured yield, grade index, and crop index on Coker 176 wee 42.67%, 7.77 kg/81 m!, 86.09, and 66.89, respectively.

Back cross hibridization of Temanggung tobacco for in¬ creasing the lincat disease resistanceThe back cross hibidization of Temanggung tobacco lines for increas¬ ing the " lincat" disease resistances was conducted Temanggung in 1997. The aim of this experiment was to produce some new Temanggung tobacco lines which ae resistant to root-knot nematode (Meloidogyne spp.) and bacteial wilt (Pseudomonas solanacearum) and have high productivity and grade index. These treatments consisted of eleven selected tobacco lines from the segregating progenies of crossing beetween Virginia and Temanggung to¬ bacco and the two Temanggung tobacco cua'vars arranged in randomized block design with three replications. The esults of this experiment showed that thee new tobacco lines (BC3.C-51, BC3.C-86, BC3.SG-86) were esis¬ tant toMeloidogyne spp. and P. solanacearum. The productivity of BC3.C-86 and BC3.SG-86 lines inceased 60.12% and 38.69% compared with Genjah Kemloko line. The productivity of BC3.C-5I line was equal to Genjah Kemloko, its quality raised 9.18%, and early loweing (dwarf* 69.65 days).
