الملخص

The African boll worm, Helicoverpa armigera, is a pest which has the tendency to become one of the most dangerous pests in Maize fields, therefore, the objectives of this study to every screen for resistance of maize genotypes for this pest and also to assess the damage in 2 locations; in central and northern of the Sudan. The study was carried to evaluate the performance of fifteen maize genotypes with two local checks against the infestation by the African bollworm, Helicoverpa armigera. Field experiments were carried out in the Gezira and Hudiba research stations, Agricultural Research Corporation (ARC), Sudan. Seventeen maize genotypes (treatments) were arranged in Randomized Complete Block Design (RCBD), with three replicates. Four parameters, namely, the incidence of leaves damage(%), ears infestation (%), number of larvae and grain yield were used as indicators for the susceptibility and tolerance or resistance of the Maize genotypes to the infestation of the African bollworm. The results were significant different ( p ≤ 0.05) between the mean infestation incidence recorded for the leaves damage indicating maximum values 1.25,1.36,1.34 in Medani for YO63,YO64,VMH4102 and 1.3,1.41,1.41 in Hudiba for YO64,MO4,VMH2015, respectively. These values indicated the potential susceptibility of Maize genotypes. on the other hand , the mean infestation incidence recorded for the first parameter (leaf damage) revealed minimum values of 0.91, 0.92 ,0.98 ,1.05 ,0.92 in Medani for VMH2000,VMH4040,PAC339,PAC999, PR89B5655 and 0.93, 1.05, 1.07, 1.03, 1.02 at Hudiba for the genotypes VMH2000, VMH4040, PAC339,PAC999,PR89B5655,respectively, indicating relative resistance; as for ear infestation, maximum values recorded in Medani were 3.34,2.52 for PAC740, VMH2015 respectively, and 1.94 in Hudiba for MO4,Hudiba-2 these values indicated potential susceptibility of Maize genotypes. The minimum values for the ear infestation were 0.7 in Medani for the genotypes VMH2000, VMH4040, PAC339, which indicate of potential tolerance / resistance of the maize genotypes. The grain yield showed significant differences (P≤0.05) between genotypes. From the obtained results genotypes MO4 , YO63 , YO64 , VMH4102 , VMH2015 , PAC740, Hudiba-2 were highly susceptible, whereas, the genotypes VMH2000 ,VMH4040, PAC339, PAC999 ,PR89B5655 had potential tolerance or resistance to the infestation by the African boll worm and thus could be considered as promising maize genotypes and we recommend their cultivation in wider range for verification of their resistance.
