Última Améliorer la tolérance à la sécheresse du tournesol : apports de l'écophysiologie et de la génétique Inra Grieu, P.; Maury, P.; Debaeke, P.; Sarrafi, A.. Le tournesol est une culture d’intérêt que l’on rencontre dans des situations de sécheresse et de sols pauvres. Il est considéré adapté à la sécheresse, bien que les bases physiologiques et les efforts d’amélioration pour la tolérance à la sécheresse restent encore insuffisants. Les agronomes qui conçoivent des modèles de culture et les généticiens n’ont pas, jusqu’à présent, partagé la même vision du choix de génotype pour améliorer une production. Cependant, il est désormais reconnu que pour améliorer efficacement cette sélection, une démarche d’interdisciplinarité est nécessaire. Cet article présente quelques travaux mettant en jeu une collaboration entre modélisateurs, écophysiologistes et généticiens pour étudier les interactions génotype x...

This study was conducted to identify physiological traits associated with cold tolerance in sunflower and to identify the genomic regions involved in their variation. A population of 98 recombinant inbred lines(RILs) and their two parentswere sown in the field as usual sowing date (control) and one or two months earlier (long-term low temperature treatments). A trait commonly used to underlying cold tolerance related to the degree of membrane damage, as well as traits associated with growth capacity(chlorophyll content, potential photochemical efficiency of photosystem II and plant dry weight) and finally those reflecting acclimation mechanism to stress conditions (osmotic potential at full turgor, and specific leaf area) have been investigated at early...

The purpose of the present study was to map quantitative trait locus (QTLs) associated with percentage of seed protein, oil and fatty acids content under different conditions in a population of recombinant inbred lines (RILs) of sunflower. Three independent field experiments were conducted with well-, partial-irrigated and late-sowing conditions in randomized complete block design with three replications. High significant variation among genotypes is observed for the studied traits in all conditions. Several specific and non-specific QTLs for the aforementioned traits were detected. Under late-sowing condition, a specific QTL of palmitic acid content on linkage group 6 (PAC-LS.6) is located between ORS1233 and SSL66_1 markers. Common chromosomic regions...

A set of sunflower recombinant inbred lines (RILs) was used to study agronomical traits under greenhouse and field conditions each with two water treatments and three replications. The difference among RILs was significant for all the traits studied in all conditions; and water treatment*RILs interaction was also observed for most of the traits in both field and greenhouse conditions. Because of the low rate of drought stress, this part of field data are not informative. Several quantitative trait loci (QTLs) were identified for yield-related traits with the percentage of phenotypic variance explained by QTLs (R2) ranging from 4% to 40%. Several QTLs for grain yield per plant (GYP) under four water treatments were identified on different linkage groups,...

Le but de cette étude était d’identifier les régions génomiques contrôlant la teneur en protéines de la graine, la masse de l’amande, la masse de la coque ainsi que la densité des graines en conditions de stress hydrique chez le tournesol (Helianthus annuus L.). Les expériences ont été réalisées à l’aide d’un dispositif en tiroirs (« split-plot » pour le régime hydrique et les lignées recombinantes fixées) avec trois blocs chacun dans deux expériences (en serre et au champ). Une variation phénotypique très significative a été observée entre les génotypes pour tous les caractères ainsi que pour l’interaction régime hydrique × génotype. Plusieurs QTL spécifiques et non-spécifiques ont été détectés pour tous les caractères dans les conditions d’alimentation...
