Abstract:

Ten maize landraces were evaluated for Turcicum blight resistance based on the low area under disease progress curve scores for the selection studies from the North Eastern Hill Region. Inbred lines V-334(C5) and CM-145 (C6) obtained from VPKAS, ICAR, Almora Uttarakhand were used as reference checks for Turcicum blight screening. Observational data were recorded based on the successive progression of lesion length and breadth. The area under disease progress curve scores of genotypes N21(3)-9, M23(2)-21, N25(3)-19, M23(9)-14, S2(2)-10, N25(2)-32, N25(3)-6, N25(3)-11, S2(2)-20, N25(5)-23, M23(9)-17, Mi4(3)-17, Mi4(3)-36 and Mi4(3)-3 were lower than that of the resistant check C6 at 28.71 and can be used in breeding programs for introducing resistance to Turcicum blight in a population. The maximum lesion area of 22.73 sq. cm, 84 days after sowing was recorded in genotype M23(2)-24. Genotype Mi4(3)-3 was a good performer for disease resistance.
