Genetic divergence and genetic gain in bread wheat through selection practices

Genetic diversity is essential to meet the diversified goals of plant breeding such as producing cultivars with increased yield, wider adaptation, desirable quality, pest and disease resistance. In this study genetic diversity and selection index of 24 genotypes of bread wheat were evaluated. The performance of 24 wheat genotypes showed that there were significant variations for the characters ...

genetic variation and genetic gain from selection in bread wheat

genetic variation is necessary factor for continued breeding and increasing genetic gain from selection in crop plants. to evaluate genetic variation and genetic gain from selection in bread wheat, 45 genotypes consisting of 9 cultivars and their 36 crosses were grown in a randomized complete block design with three replications in research farm of isfahan university of technology. the phenotyp...

Study of genetic diversity in bread wheat germplasm using nitrogen uptake and nitrogen use efficiency characteristics

In order to evaluate the traits related to nitrogen utilization and to identify the superior genotypes, 33 bread wheat landraces along three check cultivars of Chamran and Koohdasht (from Iran) and Gobustan (from the Republic of Azerbaijan) were studied in simple lattice statistical design with two replications under two treatments of non-usage and application of 200 kg/ha ammonium nitrate fert...

Genetic Analysis of Grain Yield and Yield Components in Bread Wheat using Hayman's Diallel Method

Extended Abstract Introduction and Objective: By progeny trial after a diallel crossing, the function of genes and inheritance of quantitative traits can be estimated. This increases the ability to select parental lines, to participate in crosses, and determines the management of generations in the segregating populations. Material and Methods: In order to understand the genetic structure of ...

Estimation of Genetic Components and Inheritance of Bread Wheat Agronomic Traits Using Regression Method Through Generation Mean Analysis

Studying the genetic structure of crops, including wheat, has always been one of the research priorities to increase the efficiency of breeding methods. In order to genetic analysis of some agronomic traits of bread wheat using generation mean analysis (GMA), all produced generations along with relevant parents of the two populations (Marvdasht × Rasoul and Marvdasht × Shahpasand) were evaluate...
