Abstract

Mention d'édition : 3. ed.; International audience; Watermelon mosaic virus (WMV) and zucchini yellow mosaic virus (ZYMV) are two major potyviruses infecting cucurbits. WMV is the causal agent of one of the first described cucurbit mosaic virus diseases, while ZYMV emerged as a major cucurbit pathogen causing severe yield losses only in the late 1970s. WMV infects many weeds and several crops outside cucurbits while ZYMV has a more restricted host range. Both are efficiently transmitted by aphids in a nonpersistent manner, which often results in rapid and severe epidemics in the fields. Control measures rely mainly on prophylactic methods (weeding, mulching). Cross-protection has been developed commercially to control severe ZYMV isolates. Breeders using classical and genetically engineered resistance have already released WMV and ZYMV commercial resistant cultivars in the major cucurbit crops. Important biological variability is observed among ZYMV isolates and to a lesser extent among WMV isolates. The serological and molecular variability is also high. Molecular studies revealed that WMV probably arose through recombination between two legume-infecting viruses. In addition, intraspecific recombinations seem to be common in WMV. ZYMV is presently used as a biotechnological tool to produce in cucurbit plants proteins of pharmaceutical or plant protection interest.

Abstract

Powdery mildew [Podosphaera xanthii (Castagne) Braun & Shishkoff (syn. Sphaerotheca fuliginea auct. p.p.)] is now a common disease on watermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai] in the United States. In this study, the entire available U.S. Plant Introduction collection of Citrullus Schrad. ex Eckl. & Zeyh. species was evaluated for resistance to P. xanthii race 1W. The collection consists of four Citrullus species and one Praecitrullus Pangalo species [C. lanatus var. citroides (L.H. Bailey) Mansf., C. colocynthis (L.) Schrad., C. rehmii De Winter, and P. fistulosus (Stocks) Pangalo]. Wild-type accessions tended to be more resistant more often than the cultivated species, C. lanatus var. lanatus. None were immune, eight of the 1573 accessions exhibited high levels of resistance, and another 86 demonstrated intermediate resistance. Stem and leaf disease severity were weakly correlated (r 2 = 0.64, P = 0.001). The majority of accessions having resistance were collected in Zimbabwe. Resistance was found in four species.

Abstract

La mesure directe des remontées capillaires sous cultures pose de gros problèmes expérimentaux. La méthode proposée ici est basée sur une approche indirecte du phénomène. 1- Sur un site voisin du site expérimental, soumis à des conditions identiques (mesure du profil tensiométrique, et du profil de teneur en eau), et lorsqu'un gradient ascendant de potentiel s'est établi (début de saison sèche), on bâche brusquement le site de mesure, le mettant ainsi en conditions d'évaporation et de transpiration nulle. A l'aide d'un modèle mécaniste de transfert d'eau, on estime alors les paramètres d'une fonction décrivant les variations de la conductivité hydraulique en fonction du potentiel du sol, dans la gamme de potentiels sous lesquels s'opèrent les remontées capillaires sous le profil racinaire. 2- Par une expérimentation de drainage interne, on estime dans une gamme plus élevée de potentiels la conductivité, ce qui permet de disposer de celle-ci sur une gamme étendue, sous laquelle l'essentiel des processus de remontées capillaires opèrent. 3- On reprend les valeurs issues de ces mesures dans un modèle simulant par une approche mécaniste les transferts d'eau dans le sol sous culture, et on en déduit les différents termes du bilan hydrique, dont les remontées capillaires. Le travail présente les résultats expérimentaux menés au Nicaragua sur sols volcaniques, sous culture de sorgho, et appliqués à une culture de pastèque en saison sèche. On explique ainsi l'existence ancestrale de systèmes de cultures dont le principe consiste à effectuer un travail du sol créant les conditions de mise en marche d'une pompe à remontées capillaires

Abstract

PI 525088-PMR is a watermelon (Citrullus lanatus var. lanatus) line having resistance to melon race one powdery mildew (PM) Podosphaera xanthii (syn. Sphaerotheca fuliginea auct. p.p.). The line is derived from the U.S. Plant Introduction (PI) 525088 (Citrullus lanatus var. lanatus). PI 525088PMR does not have desirable fruit quality with fruit flesh color being white to light pink and an average Brix value of 6. However, it could be a useful parent for introducing race one powdery mildew (P. xanthii) resistance into adapted watermelon cultivars.

Abstract

Parthenogenetic haploid embryos of `Crimson Sweet', `Halep Karasi', `Sugar Baby' and `Panonia F1' watermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai] were obtained after pollination with γ-irradiated (200 or 300 Gy) pollen. Some globular and heart-shaped embryos were observed in fruit harvested 2 to 5 weeks after pollination. The number of embryos per 100 seeds was highest for `Halep Karasi'. After in vitro culture, 17 haploid plants were obtained and doubled haploid lines were generated after chromosome doubling using colchicine.
