Abstract
SSR analysis of chloroplast and mitochondrial genomes of cultivar lines and wild species of sunflower (Helianthus L.) were completed. The polymorphism of 18 microsatellite loci of the chloroplast and mitochondrial genomes was investigated. Based on the obtained data was constructed dendrogram showing the genetic diversity of chloroplast and mitochondrial genomes of sunflowers. The studied species were clustered into annual and perennial. This set of novel polymorphic SSR markers can be useful for breeders and molecular biologists for the genetic diversity analysis, lines identification and improve breeding.
Highlights
Sunflower is a valuable crop cultivated all over the world
Molecular markers are among the pre-requisites to accelerate the crop breeding program through genomics assisted breeding (Bohra et al, 2017)
The samples was represented by H. decapetalus, H. divaricatus, H. grosseserratus, H. hirsutus, H. microcephalus, H. occidentalis, H. rigidus, H. salicifolius, H. strumosus, H. tuberosus, H. argophyllus, H. bolanderi, H. debilis, H
Summary
Sunflower is a valuable crop cultivated all over the world. Modern research methods allow the most effective study of the genetic diversity of organisms and use it in population and breeding studies (Song et al, 2018). Plant breeding still rely heavily on the inner genetic resources, which are essential to accurately identify genotypes and to delineate the various genetic relationships between available accessions in germplasm collections. These resources can be utilized effectively to preserve and develop the species and to enhance its applications (Mornkham et al, 2016)
