“…About half of these, 2,519 accessions, represent the world’s largest wild relatives sunflower collection, comprising 53 species – 39 perennial and 14 annual species ( Seiler et al, 2017 ). Another large collection for sunflower (cultivated and wild) is maintained at the Vavilov Institute of Plant Industry, which consists of a total of 2,780 accessions from which 2,230 represent cultivated sunflower accessions and 550 wild sunflower accessions belonging to 24 species (19 perennials and 5 annuals) ( Gavrilova et al, 2014 ). Some smaller numbers of 585 accessions of H. annuus are available via GRIN-CA, the Plant Gene Resources of Canada 2 and additional 613 sunflower accessions of diverse origin are distributed by the IPK Gatersleben 3 .…”

In sunflower, molecular markers for simple traits as, e.g., fertility restoration, high oleic acid content, herbicide tolerance or resistances to Plasmopara halstedii, Puccinia helianthi, or Orobanche cumana have been successfully used in marker-assisted breeding programs for years. However, agronomically important complex quantitative traits like yield, heterosis, drought tolerance, oil content or selection for disease resistance, e.g., against Sclerotinia sclerotiorum have been challenging and will require genome-wide approaches. Plant genetic resources for sunflower are being collected and conserved worldwide that represent valuable resources to study complex traits. Sunflower association panels provide the basis for genome-wide association studies, overcoming disadvantages of biparental populations. Advances in technologies and the availability of the sunflower genome sequence made novel approaches on the whole genome level possible. Genotype-by-sequencing, and whole genome sequencing based on next generation sequencing technologies facilitated the production of large amounts of SNP markers for high density maps as well as SNP arrays and allowed genome-wide association studies and genomic selection in sunflower. Genome wide or candidate gene based association studies have been performed for traits like branching, flowering time, resistance to Sclerotinia head and stalk rot. First steps in genomic selection with regard to hybrid performance and hybrid oil content have shown that genomic selection can successfully address complex quantitative traits in sunflower and will help to speed up sunflower breeding programs in the future. To make sunflower more competitive toward other oil crops higher levels of resistance against pathogens and better yield performance are required. In addition, optimizing plant architecture toward a more complex growth type for higher plant densities has the potential to considerably increase yields per hectare. Integrative approaches combining omic technologies (genomics, transcriptomics, proteomics, metabolomics and phenomics) using bioinformatic tools will facilitate the identification of target genes and markers for complex traits and will give a better insight into the mechanisms behind the traits.

“…The Oil Crop Research Institute of the Chinese Academy of Agriculture Science in Wuhan, China, maintains 2813 sunflower accessions, predominantly cultivated (Gao et al, 2001). The Vavilov Research Institute of Plant Industry in Russia maintains 2230 cultivated sunflowers and 550 wild accessions, encompassing 5 annual and 19 perennial species (Gavrilova et al, 2014). The Institute of Field and Vegetable Crops in Novi Sad, Serbia, has a cultivated collection of several thousand lines (S. Terzic, personal communication, 2016) and a wild sunflower collection of just over 1000 accessions of 47 wild species, although they do not have seed backup of 40% of the species (Atlagić and Terzić, 2015).…”

“…Other disease resistance has been introgressed from the wild perennial species H. maximiliani Schrad. and H. giganteus L., (Liu et al, 2010), as well as alleles for achene yield and modification of fatty acids and other industrial and nutritional products (Gavrilova et al, 2014). Some of the breeding lines developed from introgressions from CWR have been listed in Table 2.…”

The Use of Crop Wild Relatives in Maize and Sunflower Breeding

Conservation of crop wild relatives (CWR) has always been predicated on the promise of new and useful traits, and thus modern genetics and genomics tools must help fulfill the promise and continue to secure the conservation of these resources. However, the vast genetic potential present in CWR is often difficult to tap, as identification of superior alleles can be hampered by the effects of the environment on expression of these alleles and masked in different genetic backgrounds; transfer of superior alleles into breeding pools to create new crop varieties can be slow and expensive. Some crop species have been more amenable to introgression of traits from wild relatives than others. In some cases, these species may be less diverged from their wild ancestors, which become a good source of mono‐ to oligogenic traits, many of which are more qualitative in nature, and sometimes of quantitative traits. Sunflower (Helianthus annuus L.) is an introgression success story, and many traits, including cytoplasmic male sterility, herbicide tolerance, drought and biotic stress resistance, and modified fatty acid profiles, have been introgressed into the cultivated gene pool from wild relatives without depression of oil yield and quality. Others, including maize (Zea mays L.), have shown little progress in widening the cultivated gene pool using exotic sources due to temporary yield depression, potential for loss of quality, and disturbance of current logistical habits. Here, we review the breeding history of sunflower and maize and explore variables that have limited the use of CWR in some species and allowed success in others. Surprisingly, in both sunflower and maize, biological limitations are similar and smaller than expected and appear to be surmountable with sufficient determination. Possible new technologies and policies to allow a deeper mining of these genetic resources in all crop species are discussed.

“…Like many other plants, selection and introgressive hybridization played a decisive role in the evolution of the cultivated sunflower. The first domesticated sunflower forms were brought by naturalists to Europe at the beginning of the 16th century, where further development of the crop took place until the 19th century (Gavrilova and Anisimova, 2017). The search for genes that served as targets for domestication and subsequent selection, as well as introgressed genes, is very relevant for elucidating sunflower evolutionary history.…”

Some results of the studies of plant genetic resources held in the VIR Department of Genetics are discussed in light of N. I. Vavilov’s theories of natural plant immunity, homologous series in hereditary variability, and interspecific hybridization. The long-term investigations resulted in identifying bread wheat, cultivated barley, oat, rye and sorghum accessions with new effective genes for resistance to diseases and pests. The large-scale immunological screening has revealed a narrow genetic diversity in wheat and barley for resistance to biotic and abiotic stressors. On the example of sunflowers, the significance of seed storage proteins for solving problems of domestication and introgressive hybridizations is demonstrated.
