IDENTIFICATION OF RUST (Puccinia helianthi Schw.) RACES IN SUNFLOWER (Helianthus annuus L.) IN TURKEY
Sunflower (Helianthus annuus L.), with its high oil quality, is one of the major and most valuable oilseed crops in the world. Sunflower rust, caused by Puccinia helianthi Schw., is one of the major foliar diseases of sunflower. The pathogen is present wherever sunflower is grown in the world and causes important yield losses when severe epidemics occur. The objective of this study was to ident...
متن کاملEffect of Bio-Agents, Neem Leaf Extract and Fungicides Against Alternaria Leaf Blight of Wheat (Triticum Aestivum L.)
The experiment was conducted under in vitro and field conditions to observe the effect of bio-agents, botanical and fungicides against Alternaria triticina. Eight treatments were taken up with three replications and data collected was analyzed using CRD. Maximum inhibition per cent mycelia growth was observed in Propiconazole (89.72%), Hexaconazole (88.44%), Vitavax (87.70%), followed by Tricho...

متن کاملAnalyses of QTL associated with resistance to Sclerotinia sclerotiorum and Diaporthe helianthi in sunflower (Helianthus annuus L.) using molecular markers
Most traits exhibit continuous variation resulting from the action of multiple genes modified by the environment. Quantitative trait loci (QTL) analysis consists in determining the location and number of genes that condition such quantitative traits and estimating the magnitude of individual gene effect by the use of analytical methods and detailed linkage map. Sclerotinia sclerotiorum and Diap...
متن کاملMetabolic Regulation of Leaf Senescence in Sunflower (Helianthus annuus L.) Plants
The leaf is the main photosynthetic organ of plants and its development a complex process governed by a combination of environmental factors and intrinsic and genetically regulated signals (Van Lijsebettens & Clarke, 1998). Usually, leaf ontogeny includes an early phase of increasing photosynthetic rates while the leaf is actively expanding, a mature phase where such rates peak and a senescence...
