... Crop ferality can play an important role in gene flow between crops and their wild relatives and introgression from artificially selected sources can have significant evolutionary consequences (Ashiq Rabbani et al., 1998;Berville et al., 2005;Snow and Campbell, 2005;Devaux et al., 2007;Gering et al., 2019). Furthermore, with the growing adoption of genetically modified (GM) crops worldwide, transgenic flow turned into a widely discussed topic and ferality an issue of concern amongst biosafety specialists. ...

... The most effective and simplest molecular methods for assessing genetic polymorphism are PCR-based techniques. Among such techniques, the Random Amplified Polymorphic DNA (RAPD) and Simple Sequence Repeats (SSR) markers are widely used, allowing rapid detection of the variability of a large number of genome loci (Sivolap and Solodenko, 1998;Sossey-Alaoui et al., 1998;1999;Markin et al., 2016;Suresha et al., 2017;Yang et al., 2018;Uma et al., 2018). The spectra of DNA fragments, obtained as a result of their amplification, can be used as genetic markers for species identification and barcoding, as well as for determining taxonomic differences between species. ...

... Interestingly, although in most plant species ferulic acid is the major bluegreen fluorophore (Morales et al., 1996), in the case of sunflower there is no ferulic acid bound to cell walls. Small amounts of caffeic acid and trichome secretions (e.g., sesquiterpenes lactones and coumarins) have been described as blue-green fluorophores in sunflower (Spring and Schilling, 1989;Olson and Roseland, 1991;Morales et al., 1996;Tourvieille de Labrouhe et al., 1997;Lichtenthaler and Schweiger, 1998;Rowe et al., 2012). These compounds could be responsible for BGF emission in our experiments. ...

... Obviously, such lines cannot be involved in commercial hybrids due to their heterozygosity and some instability since they lead to nonhomogeneous progenies. Such materials are of interest for breeding purposes when they display any useful trait for breeding, which is probably located in the introgression (Serieys, 1997;Pinochet et al., 2001Serieys, 2009. They are also of interest to map traits and to evaluate the introgression fragment content for useful and flawed traits to ensure that there is no linkage between the useful and flawed traits. ...

... This might be related to changes occurring in tissues in response to the pathogen, such as cell collapse and changes in cell wall composition. Cosson et al. (1993) and Pratts-Pérez et al. (2000) studied wild and cultivated genotypes of sunflower and identified that necrotized tissues synthesize compounds which appear to be phytoalexins. and water-soaking in advancing margins (Hancock, 1972;Lumsden and Dow, 1973). ...

... Breeding for resistance to DM usually concentrates on the search for and incorporation of major genes designated Pl into elite sunflower lines. Simple inheritance of DM genes was discovered rather early (Vranceanu and Stoenescu, 1970;Zimmer, 1974), with different race-specific single dominant resistance genes used worldwide by sunflower breeders (Vear et al., 2008a). This causes the DM pathogen to evolve new races (Ahmed et al., 2012). ...

... Partial resistance to Downy mildew has been studied in France since 2003, in a collaboration programme between INRA, CETIOM and breeders (Oléosem). First results were presented at Fargo (Tourvieille et al., 2004). This paper presents the research carried out in the last 3 years, particularly concerning large-scale trials, and discusses programmes in progress and possible use of this type of resistance in breeding. ...

... Notably, it was previously demonstrated that Ol-associated markers are located on chromosome 14 (Pérez-Vich et al. 2002;Schuppert et al. 2006;Lacombe et al. 2009;Premnath et al. 2016). Previously translocations were discussed for Heliathus genus in terms of divergence between the species, namely H. annuus and H. argophyllus were hypothesized to differ by two reciprocal translocations (Chandler et al. 1986;Quillet et al. 1995), with ve non-reciprocal translocations between the chromosomes of H. annuus and H. argophyllus having been additionally reported (Heesacker et al. 2009). Eight translocations were discussed among the differences between H. annuus and H. petiolaris (Burke et al. 2004). ...

... Similarly, Widuri et al. [52] observed this reduction effect in Phaseolus lunatus only after a prolonged water deficit period. In this sense, other authors demonstrated that root length was positively correlated with drought resistance [52][53][54]. Khalil et al. [55] proved the role of soil texture on tolerance to water stress related to the decrease in fresh weight in roots and shoots. Similar results have been reported on other growth parameters, such as the reduction in vegetative growth or the number of leaves in Phaseolus vulgaris [56,57]. ...

... Bohorova and Atanassov [9] showed that anther cultures of hybrid sunflower are more efficient in forming callus tissue in terms of both the intensity and the rate of the process compared with sunflower lines and cultivars. The dependence of morphogenetic responses on the specific genetic features of individual sunflower genotypes has been described in several research articles [62][63][64][65]. When studying the genetic control of organogenesis in sunflower, Sarrafi et al. [62] observed that both the general and specific combining ability were significant for shoot regeneration and rhizogenesis. ...
