“…IMIH cultivars were second with 40.88%, followed by NRH cultivars with 9.65% (Table 8). These results support those of Kaya et al, (2009) indicating that over 90% of the sunflower areas in the Thrace region were infested with new broom- rape races and that broomrape and weed control were the main factors in sunflower production.…”

About 65% of sunflower production in Turkey, which is the world's 11 th largest producer of sunflower based on the FAO data, occurs in the Thrace region. The biggest problem in sunflower areas in the Thrace region is broomrape (Orobanche cernua L.). Three types of sunflower cultivars are planted in the region, namely hybrids genetically resistant to broomrape (GRH), nonresistant ones (NRH) and IMI (Imidazolinone) herbicide resistant ones (IMIH), which control both broomrape and key weeds in sunflower production. The adoption situation and the performances of these three sunflower hybrid types were studied in the research. The research data was obtained from 571 agricultural enterprises, which were determined based on the Stratified Random Sampling Method in the Thrace region. Sunflower is grown on 42% of the total cultivated land surveyed in the research and accounts for 23% of the total agricultural revenue. The adoption rate and degree of IMIH and GRH sunflower hybrids were calculated to be over 90%. The highest yield (1,915.10 kg ha-1) was obtained from GRH hybrids in the research areas. A high yielding potential and easier weed control are seen by the farmers as being among the most important factors for choosing a particular type of sunflower seed. Statistical differences were observed among the sunflower hybrid types based on seed yield, revenue, and seed amounts. The highest net profit was obtained from GRH hybrids in the study. Additionally, based on the results, NRH hybrids were found to be more profitable than IMI hybrids.

Sunflower is one of the leading oilseed crops and it is widely grown in the Thrace region of Turkey. In 2017, in Turkey as a whole, oilseed and confectionary sunflowers were grown on 779.622 ha with a total production of 1 964 385 t of seed, and average yields of 2.64 t ha−1 for oilseed and 1.67 t ha−1 for confectionary types. Turkey is one of the important countries for crop diversity and has been described as a microcenter for some crops, which originated in different parts of the world. Landraces of sunflower (Helianthus annuus L.) show significant diversity in Turkey and have been collected in the framework of the “National Industrial Plant Genetic Resources Project” (NPGRP). Nine hundred and thirty two oilseed and confectionary sunflower accessions are in longterm conservation in the National Seed Gene Bank of Turkey. The mission of the National Sunflower Research Project is to develop improved germplasm and hybrid varieties by conventional and biotechnical breeding techniques in Turkey. New germplasm and breeding lines have been developed to improve oilseed and confectionary sunflower hybrids with desired characters including high yield and oil quality, resistance to diseases such as: Plasmopara halstedii (Farl.) Berl de Toni., Puccinia helianthi Schw., and Orobanche cumana Walr. Adverse conditions are also taken under consideration. These studies are integrated with agronomic and other related research.

“…Initially, all of them were named as race F though the relationship between the different F races has not been studied. Nowadays, populations overcoming resistance sources to race F, named as races G and H, have been identified in most of these countries (Kaya et al, 2009; Pacureanu-Joita et al, 2009; Shindrova and Penchev, 2012; Antonova et al, 2013; Martín-Sanz et al, 2016). As mentioned for race F, no comparative studies have been conducted between races G and H reported in different countries.…”

An SSR-SNP Linkage Map of the Parasitic Weed Orobanche cumana Wallr. Including a Gene for Plant Pigmentation

Sunflower broomrape ( Orobanche cumana Wallr.) is a holoparasitic plant that causes major yield losses to sunflower crops in the Old World. Efforts to understand how this parasitic weed recognizes and interacts with sunflowers are important for developing long-term genetic resistance strategies. However, such studies are hampered by the lack of genetic tools for O. cumana . The objectives of this research were to construct a genetic linkage map of this species using SSR and SNP markers, and mapping the P g locus that is involved in plant pigmentation. The genetic map was developed from the progenies of a cross between the O. cumana inbred lines EK-12 and EK-A1, which originated from populations belonging to two distant and geographically separated gene pools identified in Spain. The inbred lines also differed in plant pigmentation, with EK-A1 lacking anthocyanin pigmentation ( p g p g genotype). A genetic map comprising 26 SSR and 701 SNP markers was constructed, which displayed 19 linkage groups (LGs), corresponding to the 19 chromosome pairs of O. cumana . The total length of the map was 1795.7 cM, with an average distance between two adjacent positions of 2.5 cM and a maximum map distance of 41.9 cM. The P g locus mapped to LG19 between the SNP markers OS02468 and OS01653 at 7.5 and 3.4 cM, respectively. This study constitutes the first linkage map and trait mapping study in Orobanche spp., laying a key foundation for further genome characterization and providing a basis for mapping additional traits such as those having a key role in parasitism.
