Kirkuk University’s Master’s Dissertation: On Performance Evaluation in Growth & Production Indicators of Local Hybrid on Yellow Vorn

College of Agriculture,  University of Kirkuk discussed a master dissertation on performance evaluation in growth and productivity indicators of local crosses of two rivers and accessed hybrids of maize, estimation of genetic parameters and pathway coefficient analysis under different levels of salicylic acid by the postgraduate student, Mr. Hossam Sobhi Ahmed. The dissertation demonstrated using of three concentrations of salicylic acid (0, 100, 200) ppm and nine introduced hybrids (Saginto, PL472, Simon, PL538, Podio, PL700, Torro, 426t6099, Dario), as well as a hybrid Local Nahrin designed the complete random sectors according to the split panels system with three replications to evaluate the performance of the hybrids, study the genetic parameters, phenotypic, genetic and environmental correlations and analyze the path factor at each concentration of salicylic acid. The dissertation confirmed that there was no response to salicylic acid in all the studied traits except for female flowering and the genotypes varied in their performance, as the PL700 genotype was superior in most of the traits, including the components of the yield, followed by the Torro structure in the trait of yield and ear diameter. The dissertation recommended using of other concentrations of salicylic acid, spraying in other than the appropriate conditions, as it did not show any superiority for any of the concentrations used in the study, and other studies that include environmental factors such as planting distances, fertilization and planting dates for the synthetics to obtain the highest yield.
