Varietal reaction of ginger and turmeric against major fungal diseases

Five ginger cultivars viz., SG-536, V₁S₁-8, ACC-64, V₃S₁-8, Garubathan and nine turmeric cultivars viz., RH-5, Rajendra Sonia, PTS-12, PTS-43, PTS-62, ACC-360, ACC-361, JTS-1 and JTS-2 were evaluated for their resistance to major fungal diseases and yield performance under West Bengal condition during 2001–02.

Results indicated that none of the cultivars of ginger and turmeric tested was free from infection though the degree of infection varied. Among five cultivars of ginger, V₁S₁-8, and V₃S₁-8 showed lowest incidence of leaf spot and rhizome rot, respectively, while highest yield was obtained from Garubathan. Out of nine cultivars of turmeric, PTS-12, PTS-63 and ACC-360 were found to be resistant to leaf blotch and leaf spot diseases. However, RH-5 and Rajendra Sonia though susceptible to the leaf blotch and leaf spot appreciably recorded higher yield than other cultivars.
