Genetic variability in common wheat germplasm based on coefficients of parentage
The characterization of genetic variability and an estimate of the genetic relationship among varieties are essential to any breeding program, because artificial crosses among less similar parents allow a larger segregation and the combination of different favorable alleles. Genetic variability can be evaluated in different ways, including the Coefficient of Parentage (COP), which estimates the...
متن کاملGENETIC DIVERSITY ASSESSMENT OF RICE (Oryza sativa L.) GERMPLASM USING SSR MARKERS
Rice Diversity PIC SSR marker Diversity at molecular level among thirty rice genotypes, selected based on earliness and morphometric diversity was evaluated through five SSR markers associated with days to heading. Three primers viz., RM147, RM167 and RM215 showed polymorphism for growth duration related traits. A total of 17 alleles were detected among the 30 rice genotypes with an average of ...
متن کاملGenetic diversity and genetic relationships of japonica rice varieties in Northeast Asia based on SSR markers
Genetic diversity and the relationship among nine japonica rice groups consisting of 288 landraces and varieties in different geographical origins of Northeast Asia (China, Japan, Korea, Democratic People's Republic of Korea) and the Russian Far East district of the Russian Federation were evaluated with 154 simple sequence repeat (SSR) markers. A total of 823 alleles were detected. The observe...
متن کاملInheritance of the fertility restoration and genotyping of rice lines at the restoring fertility (Rf) loci using molecular markers
The combination of cytoplasmic male sterility (CMS) in one parent and a restorer gene (Rf) to restore fertility in another are indispensable for the development of hybrid varieties. To genotype rice lines at the restoring fertility (Rf) loci, 38 lines were crossed with a sterile tester (rfrf) line. Pollen fertility test was performed to identify sterile and fertile F1 hybrids. Seven lines were ...
متن کاملGenetic Distance Based on SSR Markers and Testcross Performance of Maize Inbred Lines
The identification of parental inbred lines to develop superior hybrids is a rather costly and time-consuming step in maize breeding. In some cases, pedigree information has been used to select diverse parental lines. In the case of Iranian maize inbred lines, this information is not fully available. In this study we investigated the genetic distance (GD) based on Simple sequence Repeats (SSR) ...
