“…In this study we are measuring a-tocopherol, the most biologically active form of vitamin E. The U.S. Department of Agriculture (USDA), Agricultural Research Service reports vitamin E content for a Florida-grown 'Hass' avocado to be %19.7 mgÁg -1 . A study of tocopherol content in sunflower (Helianthus annuus) seeds reported a heritability ranging from 0.67 to 0.78 (Del Moral et al, 2012), making vitamin E a good candidate for selection in that species.…”

Avocado (Persea americana) is a subtropical tree prized for its large and nutritious fruit. Although native to Mesoamerica, avocado is now grown in tropical and subtropical regions around the world, and consumer demand for avocado continues to grow at a considerable rate. Despite the appeal of avocado, its genetic improvement has been slow owing to substantial land and labor requirements combined with the fact that young trees do not produce fruit for several years and a pollination system that makes it difficult to produce genetic crosses. Molecular markers promise to accelerate the rate of breeding progress, especially for simple traits of high heritability. One of the distinguishing features of the avocado fruit is the presence of a number of compounds that have been linked to human health. As a prelude to the use of molecular markers for the improvement of nutritional traits, this article reports estimates of the heritability of carotenoids, β-sitosterol, and α-tocopherol content (the most biologically active form of vitamin E) in ripe avocado fruit. Each of these three compounds has been linked to beneficial health outcomes, and each is shown to have a sufficiently high heritability to predict successful marker-assisted selection.

“…It was shown in sunflower that a genetic variability for their content could be exploited in breeding and QTL were mapped (Del Moral et al, 2012, Haddadi et al, 2011, Merah et al, 2012. The tocopherols B. napus orthologs of Arabidopsis genes were identified and functionally analyzed (Fritsche et al, 2014), providing precise tools for tocopherol profile modifications by breeding.…”

-Due to the geographical specialization in oilseed world production, Europe has a major role to play in winter oilseed rape and sunflower breeding. Mainly based on the most recen t results, this review aims to identify the main research and breeding targets for these two crops, as seen through publications, with an attempt to suggest what are opportunities and challenges in these research fields. Growing a healthy and yielding crop remains the key driver for agronomic production. However sustainability and environmental profiles of the cultivar are now entering the field of play: The sustainability concern invested the field of resistance to diseases. Nitrogen use efficiency became an important target for Brassica napus, and crop resilience toward drought stresses is the way chosen in Helianthus annuus breeding for yield improvement. Significant advances are underway for quality traits, but the uncertainty on nutritional and industrial demand may explain why the product diversification remains low. Keywords:Brassica napus / Helianthus annuus / breeding target / biotic / abiotic Résumé -Champs de recherche, défis et opportunités de la sélection variétale des oléagineux européens. En raison de la spécialisation géographique dans la production mondiale d'oléagineux, l'Europe joue un rôle majeur dans la sélection de colza d'hiver et de tournesol. Reposant principalement sur les derniers résultats disponibles, cette revue cherche à identifier les principaux objectifs de recherche et de sélection de ces deux cultures, au regard des publications, et tente de suggérer quels sont les opportunités et défis de ces domaines de recherche. Faire croître des cultures saines et à haut rendement demeure un objectif clef de la production agronomique. Cependant la durabilité et les profils environnementaux de la variété cultivée entrent maintenant en ligne de compte : la préoccupation de durabilité a investi le champ de la résistance aux maladies. L'efficacité de l'utilisation de l'azote est devenu un objectif important pour Brassica napus, et la résistance des cultures au stress hydrique est l'une des voies majeures retenues pour la sélection chez Helianthus annuus. Des progrès significatifs sont en cours pour améliorer les traits qualitatifs, mais l'incertitude de la demande nutritionnelle et industrielle peut expliquer pourquoi la diversification de la production reste faible.

“…Therefore, given the fact that tocopherol content is a multifactorial complex polygenic trait, several studies mapped QTL that control the seed contents of α-Toc, β-Toc, γ-Toc, δ-Toc, and T-Toc in maize [24,28,29], rapeseed (B. napus) [30][31][32], sunflower [33,34], and other plants [35].…”

Tocopherols are secondary metabolites synthesized through the shikimate biosynthetic pathway in the plastids of most plants. It is well known that α–Tocopherol (vitamin E) has many health benefits for humans and animals; therefore, it is highly used in human and animal diets. Tocopherols vary considerably in most crop (and plant) species and within cultivars of the same species depending on environmental and growth conditions; tocopherol content is a polygenic, complex traits, and its inheritance is poorly understood. The objective of this review paper was to summarize all identified quantitative trait loci (QTL) that control seed tocopherols and related contents identified in maize (Zea mays) during the past two decades (2002–2022). Candidate genes identified within these QTL regions are also discussed. The QTL described here, and candidate genes identified within these genomic regions could be used in breeding programs to develop maize cultivars with high, beneficial levels of seed tocopherol contents.
