| Abstract | ||
| A field experiment was carried out at the research station of field crops department at College of Agriculture at Tikrit University, which is about 12 km from center of Tikrit city, during two winter agricultural seasons 2021-2022 AD and 2022-2023 AD. Experiment included tow factor the first ten genotypes of six-row barley were Warka Aswad, Shuaea Al Khair, Hadar Aswad, Amal, Buraq, Samir, Rayhana, Arifat, and Ibaa 99, and the seconed three spray concentrations of zinc (0.60, 120) mg. liter, and experiment was implemented according to Randomized Complete Block Design (R.C.B.D), with three replications and a split-plot arrangement. Traits of number of spikes per m2, number of grains per spike, weight of a thousand grains, grain yield, total biological yield, and harvest index were studied. Stability was estimated according to method of Eberhart and Russell (1966) and genetic, environmental, and phenotypic correlations. The following results were reached: Linear effect of environments and environments was highly significant for all traits studied and was effect of genotypes was highly significant for all traits except grain yield, and the joint interaction between genotypes and environments was highly significant for all of studied traits except for biological yield trait. Effect of linear component of joint interaction between genotypes, environment, and clustering deviation with experimental error were highly significant for all traits except for traits of grain yield and biological yield, and it was Genetic and phenotypic correlation is positive and highly significant for traits of number of spikes per m2, number of grains per spike, weight of a 1000 grains and grain yield, and that genotypes Amal, Rayhana, Shuaa and Ibaa 99 were genetically stable of grain yield. | ||
