“…0.05). Oilseed-type and confectionerytype sunflower cultivars differ for achene oil content and proportion of hull (Fernández-Martínez et al, 2009), but the kernels of confectionery-type sunflowers possess a high oil content similar to oilseed-type sunflowers (Buendia and d'Appolonia, 1986), which was confirmed in the cultivars evaluated in the present research.…”

“…These tocopherol levels are within the range of variation reported in a large germplasm collection of sunflower, from 119 to 491 mg kg -1 seed kernel (Velasco et al, 2010). α-tocopherol was in all cases the predominant tocopherol form accounting in all cases for more than 96% of the total tocopherols, which is the typical tocopherol profile in sunflower except for breeding material in which alternative tocopherol profiles have been developed (Fernández-Martínez et al, 2009). Oilseed-type cultivars averaged higher tocopherol contents than confectionery-type cultivars in both environments (Spain: t 5 -2.16, P , 0.05; Morocco: t 5 -2.92, P , 0.01).…”

“…Previous studies have focused on the study of the heritability of achene weight (Miller and Fick, 1997;Fernández-Martínez et al, 2009), but to our knowledge there is no information on the influence of genetic and environmental factors on the kernel weight of sunflowers. The main factor explaining the observed variation in kernel oil content was the genotype 3 location interaction, with no significant contribution of genotypes or locations (Table 1).…”

“…Sunflower seeds entering the non-oil markets, also known as confectionery or confection seeds, are generally produced from specific confectionery-type cultivars characterized by large achenes that are black (or grey) and white striped and contain a high hull percentage. Seeds from oilseed-type cultivars that produce smaller black achenes with low hull content (Fernández-Martínez et al, 2009) are also destined for the food market in some areas. Countries such as US, Spain, Turkey and China mainly demand confectionery-type seeds for the food market (Lofgren, 1997;Kaya, 2004;Zhang, 2004); although customers in other areas such as the Balkan region and Morocco prefer oilseed-type seeds (Kaya, 2004;El Asri et al, 2006).…”

321significantly greater average tocopherol and phytosterol contents, though confectionery-type cultivars with levels of tocopherols and phytosterols similar to the best oilseed-type cultivars were identified. The large variations in kernel tocopherol and phytosterol contents found in this research suggest that there is room for breeding for increased levels of these compounds in order to develop healthier sunflower cultivars for the human food market.

“…at each backcross generation. Additionally, dominant alleles need to be introgressed only in one of the parents of the hybrid (Fernández-Martínez et al, 2009). But on the other hand, the continuous use of single dominant genes of resistance has facilitated the development and rapid spread of new races of the parasite, demanding a new cycle of identification of genes of resistance to the new race and their introgression into elite lines (Fernández-Martínez et al, 2015).…”

-Sunflower broomrape (Orobanche cumana Wallr.) parasitization on sunflower was first observed at the end of the 19th century and has continued since then jeopardizing sunflower cultivation in many areas of Europe and Asia. A distinctive characteristic of the O. cumana-sunflower parasitic system is that it is mainly governed by a genefor-gene interaction. This determines complete resistance in the host controlled by dominant alleles at a single locus, which facilitates the management of the resistance for hybrid seed production. But on the other hand avirulence in the parasite is also controlled by dominant alleles at a single gene. Monogenic, dominant resistance exerts a strong selection pressure on the parasite that maximizes the probability of overcoming resistance mechanisms in a short period of time. This has in fact resulted in a number of physiological races that periodically surpass all the available resistance sources. The spread of populations to new areas and the subsequent hybridization between populations is another mechanism creating genetic diversity in sunflower broomrape and allegedly recombination of avirulences genes. After more than one century of coexistence, genetic resistance to broomrape in sunflower has to be focused under an integrated approach that considers not only the characterization of resistance mechanisms in the host, but also the genetic and physiological bases of avirulence in the parasite. From the perspective of genetic resistance in sunflower, most important is not relying only on single dominant genes, but following instead pyramiding strategies. These should give priority to combining complementary mechanisms of resistance under both qualitative (vertical) and quantitative (horizontal) genetic control. These aspects are discussed in the paper. Keywords:Avirulence genes / broomrape / genetic resistance / Orobanche cumana / sunflower Résumé -Recherche de résistance à l'orobanche chez le tournesol : une vision intégrée. Le parasitisme de l'orobanche du tournesol (Orobanche cumana Wallr) a été observé à la fin du 19 e siècle et a continué depuis lors, mettant en péril la culture du tournesol dans de nombreuses régions d'Europe et d'Asie. Une caractéristique spécifique de l'interaction O.cumana-Tournesol est qu'elle est principalement régie par une interaction gène pour gène. Elle détermine une résistance totale de l'hôte contrôlée par des allèles dominants à un seul locus, ce qui facilite la gestion de la résistance pour la production de semences hybrides. Mais d'un autre côté, l'avirulence du parasite est également contrôlée par les allèles dominants d'un seul gène. Monogénique et dominante, la résistance exerce une forte pression de sélection sur le parasite qui maximise la probabilité de surmonter les mécanismes de résistance dans un court laps de temps. Cela a en fait abouti à un certain nombre de races physiologiques d'orobanche qui contournent régulièrement toutes les sources de résistance disponibles. La propagation des populations en de nouveaux lieux et l'hyb...
