In 2009, the F₁ seed was obtained from line x tester cross. F₁ seeds have been planted in 2010 according to the randomized complete block design with four repeated and for the yield and yield components, general combining ability, specific combining ability of parents have been predicted. In addition, the percentage of heterobeltiosis for the yield and plant height was determined. It was found as result that, the line of R4062xR4046 has capable transferring of its yield, kernel row number, number of kernels on the row characters to offspring`s with very high rates, so that it can be used for this purpose. Also the core genes of R4062 and R4046 were revealed greatly resemble each other in the molecular analysis. Among the testers, the FR697 can be used as a good tester in the breeding programs. Among the hybrid crosses, R4062xFR697 is superior for grain yield and the hybrid combination of R4046xGS3507 in terms of grain yield, ear placement and number of kernels on the row was formed promising hybrid combinations. Dendogram analysis of these genotypes shows that these genotypes are genetically distant relatives, is noteworthy. As a result of examination of these combinations` other agronomic and quality features, it is concluded that these genotypes can be handled as hybrid variety.
