Evaluating the Performance of the Lines and Their Half Diallel Cross in Maize (Zea mays L.) Under Plant Density

Abstract

Two field experiments were conducted during spring and autumn season of 2020, which were carried out at the Research Station of the College of Agriculture, Anbar University, in the first season The lines were introduced into the Half Diallel cross-program according to the second method proposed by [24]. the second season the experiment was applied during the autumn season of 2020 in a split-block arrangement according to a randomized completely -block design with three replications. The main block included the plant density, which was expressed through the distance between the holes. While the secondary block occupied the genotypes (lines + crosses). The results of the analysis showed that there were significant differences between densities and genotypes
