“…Other criteria to equilibrate the marker distribution included single-copy versus multiple-copy markers and markers that amplified in both A-and D-subgenomes. In addition, most of the selected markers were reported as polymorphic in previous diversity studies (Bertini et al, 2006;Abdurakmonov et al, 2007;Lacape et al, 2007;Shen et al, 2011;Yu et al, 2012a;Mishra and Fougat, 2013;Cai et al, 2014;Elçi et al, 2014). The sequence of individual primer pairs can be found in the CMD (www.cottongen.org).…”

Introduction Cotton (genus Gossypium, Malvaceae) is a major natural fiber crop used by the textile industry and is an important oil crop, as well as a byproduct provider (seeds for cattle feed, short fibers to obtain cellulose for chemistry, etc.). Although the EU represents only 1.2% of the world's cotton production with 283,400 metric tons of raw cotton (Cotton Inc., 2017), the crop plays a determinant role in economic and social aspects of countries like Greece and Spain. The two countries account for 81.4% and 17.3% of the total European output, respectively (Eurostat, 2016). These regions provide cotton plants with high boll yields and high fiber quality due to the specialized, professional, and intensive farming practices being implemented. Nevertheless, there is a scarcity of research on European cotton, especially related to genetic diversity and molecular marker analysis. An enhanced understanding of both of these topics would be highly beneficial for developing new breeding strategies. The success of plant breeding programs mainly depends on the available genetic variability of crops. This variance depends on the genetic relationship and diversity between and within plant groups (Yu et al., 2012a; Abdellatif and Soliman, 2013). Thus, having a set of varieties that globally represent useful alleles is critical in any breeding program. It requires the management, conservation, and evaluation of valuable cotton materials while maintaining a continued supply of new germplasm. This plant breeding set could be made of new or old improved varieties with yield potential to our crop environment and other related wild materials or different species with desirable traits (Kaur et al., 2014). Nowadays, more than 95% of world cotton production comes from American cotton species Gossypium hirsutum L. and Gossypium barbadense L. (Upland and Pima cotton, respectively) (Abdurakhmonov et al., 2012). Upland varieties, which represent 90% of the total, are appreciated for their high yield and wide adaptability. Conversely, Pima varieties are cultivated for their fiber length and quality. Both New World species are allotetraploidic (AD) with 2n = 4x = 52 chromosomes (Fryxell et al., 1992) and can be cross-pollinated for commercial purposes in order to interchange traits via backcrossing or segregating

BackgroundCotton germplasm resources contain beneficial alleles that can be exploited to develop germplasm adapted to emerging environmental and climate conditions. Accessions and lines have traditionally been characterized based on phenotypes, but phenotypic profiles are limited by the cost, time, and space required to make visual observations and measurements. With advances in molecular genetic methods, genotypic profiles are increasingly able to identify differences among accessions due to the larger number of genetic markers that can be measured. A combination of both methods would greatly enhance our ability to characterize germplasm resources. Recent efforts have culminated in the identification of sufficient SNP markers to establish high-throughput genotyping systems, such as the CottonSNP63K array, which enables a researcher to efficiently analyze large numbers of SNP markers and obtain highly repeatable results. In the current investigation, we have utilized the SNP array for analyzing genetic diversity primarily among cotton cultivars, making comparisons to SSR-based phylogenetic analyses, and identifying loci associated with seed nutritional traits.ResultsThe SNP markers distinctly separated G. hirsutum from other Gossypium species and distinguished the wild from cultivated types of G. hirsutum. The markers also efficiently discerned differences among cultivars, which was the primary goal when designing the CottonSNP63K array. Population structure within the genus compared favorably with previous results obtained using SSR markers, and an association study identified loci linked to factors that affect cottonseed protein content.ConclusionsOur results provide a large genome-wide variation data set for primarily cultivated cotton. Thousands of SNPs in representative cotton genotypes provide an opportunity to finely discriminate among cultivated cotton from around the world. The SNPs will be relevant as dense markers of genome variation for association mapping approaches aimed at correlating molecular polymorphisms with variation in phenotypic traits, as well as for molecular breeding approaches in cotton.Electronic supplementary materialThe online version of this article (doi:10.1186/s12870-017-0981-y) contains supplementary material, which is available to authorized users.
