Breeding Material

Determination of genetic diversity and population structure of breeding material is an important prerequisite for discovering novel and valuable alleles aimed at crop improvement. This study’s main objective was to characterize genetic diversity and population structure of a collection representing a 40-year long historical period of barley (Hordeum vulgare L.) breeding, using microsatellites, pedigree, and phenotypic data. The set of 90 barley genotypes was phenotyped during three growing seasons and genotyped with 338 polymorphic alleles. The indicators of genetic diversity showed differentiation changes throughout the breeding periods. The population structure discriminated the breeding material into three distinctive groups. The principal coordinate analysis grouped the genotypes according to their growth habit and row type. An analysis of phenotypic variance (ANOVA) showed that almost all investigated traits varied significantly between row types, seasons, and breeding periods. A positive effect on yield progress during the 40-year long breeding period could be partly attributed to breeding for shorter plants, which reduced lodging and thus provided higher yield stability. The breeding material revealed a considerable diversity level based on microsatellite and phenotypic data without a tendency of genetic erosion throughout the breeding history and implied dynamic changes in genetic backgrounds, providing a great gene pool suitable for further barley improvement.

Simple Sequence

Investigation was carried out at the laboratory of Biotechnology, Faculty of Agriculture, Damascus University, during the season 2017-2018. Seven varieties were planted to determine the degree of genetic similarity using SSR-technique (Simple Sequence Repeats), and 14 double primers were used for this purpose. The analysis results revealed that all primers showed polymorphism among the evaluated varieties, except Bmag0385. primers produced a total of 42 alleles with a polymorphic percentage of 88.27%. The number of alleles for each primer varied from 1 allele for the primer (Bmac0067) to 7 alleles for the primer (Bmag0006) in average of 3 alleles per primer. Cluster analysis and Dendrogram showed the highest degree of genetic similarity between variety Arabi asuad  and variety Arabi abiad (0.7619). While it was low between variety Fourat4 and variety Arabi abiad (0.3571), and varieties Fourat4 and Fourat3 (0.3571) which indicated wide genetic diversity among them.
