Mapping of quantitative trait loci for resistance to turcicum leaf blight in maize (Zea mays L.)

Turcicum Leaf Blight (TLB) is a common foliar disease of maize. The aim this study was to find quantitative trait loci (QTL) for TLB resistance in By crossing two inbred lines, CM 212 (susceptible) and 145 (resistant), mapping population developed, which evaluated environments namely E1 (Varanasi, U.P., India; 250 N, 830 E) E2 (Nagenahalli, Karnataka, 120 760 E). Data on four severity traits viz., Percent Disease Index (PDI), Area Under Progress Curve based PDI (AUDPC-PDI), Lesion (LA), LA (AUDPC-LA) were generated locating QTLs. Fifteen QTL intervals located chromosomes 1, 2, 4, 5, 6 9. Out these fifteen QTLs, QTLs reported 1 5 at E1; seven identified E2, where chromosome area under progress curve one lesion area. Additionally, pooled environment, six exhibited the LOD values range 2.64 7.77, corresponding R2 10.80 17.74 individual across
