Field Screening of Maize (Zea mays L.) Genotypes against Turcicum Leaf Blight (TLB) under Artificial

Background: There are a difference of critical questions facing tropical maize help, such as affliction infestation, bug/pest and grass problems. Foliar diseases specifically cause significant misfortunes in agricultural yield. Leaf blight, popular as northern leaf blight, is a disease of maize leaves provoked by an overgrowth fungus. Therefore, it was unavoidable to develop beginnings of resistance to TLB and then a field experiment was administered to study the performance of 64 genotypes (44 test crosses, 11 lines, 4 examiner and 5 checks) During Spring 2021-22 at the Agricultural College Farm, Bapatla.Methods: Screening was carried under field environments by adopting an artificial affliction inoculation technique Disease score was written at tasseling, 20 DAT and maturity stages by utilizing 1-9 scale.Results and Discussion: At maturity stage 12 crosses, seven lines and individual check showed resistant response (R); 25 crosses, 4 inbreds, one check presented moderately opposing reaction (MR); 7 crosses, 3 inbreds and individual check showed moderately naive reaction (MS) and individual inbred, two checks demonstrated susceptible reaction (S) under field protect. Conclusion: The lines VL171488-2, VL18828, VL19705-8, VL18142, VL175869, SNL19582-22 and tester LM13 presented resistant ailment reaction for TLB bacterium at phenotypic level. These lines can be used from now on TLB resistance training programmes.
