Evaluation of some maize (Zea mays L.) genotypes for resistance to stem borer (Chilopartellus (Swinhoe) infestation under surface irrigation at Takroof, Kassala State, Sudan
Abstract
The field experiments were conducted at Agricultural Research Corporation (ARC) , Kassala and Gash Research Station Farm, Takro of, Sudan. During the two winter seasons (2016/017 and 2017/018) respectively to evaluate some grain maize genotypes for resistance to stem borer and identify the most tolerance of these genotypes to Stem Borer infestation. Thirteen (STB.G1, STB.G2, STB.G3, STB.G4, STB.G5, STB.G6, STB.G7, STB.G8, STB.G9, STB.G10, STB.G11) maize genotypes were used in this study: with two check of maize variety (check. 1(Mugtama45) and ckeck. 2 (Var.113),). The experiments were arranged in Randomized Complete Block design (RCBD) with three replications. The data collected were used in this study were : Germination percentages, plant population, plant height, ear height, ear length, days to 50% Tasselling, days to 50% silking, ear length, ear diameter, cob diameter, number of rows/ear, number of kernels/row, 100 Kernel weight and Yieldkg/ha. Results showed that the most encouraging genotypes (STB.G 11, STB.G10, STB.G 4, STB.G 6 and STB.G8) of maize production at Kassala state were obtained a high value for potential of grain yield (4132, 3723, 3611, 3302 and 3264kg/ha) respectively, and for the most important of yield components. Among the traits considered, the yield (kg/ha) was the most promising as an indicator of tolerance to stem borer infestation.
