ADAPTAWHEAT will show how flowering time variation can be exploited for the genetic improvement of the European wheat crop to optimise adaptation and performance in the light of predicted climate change. It will test current hypotheses that postulate specific changes in ear emergence and the timing and duration of developmental phases, which are thought of as components of ear emergence, will improve wheat productivity. Precise genetic stocks varying in specific flowering time elements and subjected to genotyping and characterisation with diagnostic markers for key flowering time genes will be used to test these hypotheses. They will be phenotyped at the molecular (transcript abundance), physiological (growth stage dissection) and agronomic (yield components) levels in multiple field trials located at sites in Europe that represent regional agricultural diversity and at non European locations that have mega environments of relevance. Controlled environment experiments will investigate specific environmental interactions including day length, ambient temperature, and heat stress. Data analysis will aid the construction of new wheat flowering models that can be used to refine existing hypotheses. They will allow standing genetic variation for flowering time in European germplasm to be deployed more efficiently in wheat breeding programmes. This knowledge will be used to inform searches for specific phenotypic and molecular variants in diverse and non adapted wheat germplasm panels provided by consortium members. Vital novel genetic variation will be efficiently imported into the germplasm of European wheat breeders. The project will deliver new diagnostic markers for genotyping, molecular reporters for novel breeding selection strategies and the tools and knowledge necessary for a combined physiology and genomics led predictive wheat breeding programme. A conduit for these outcomes will be three SMEs, who will exploit the tools developed to deliver these outcomes.

The project has been conceived to promote the culture of grain legumes in Europe by identifying priority issues currently limiting grain legume cultivation and devising solutions in term of novel varietal development, culture practices, and food uses. LEGATO will develop tools and resources to enable state of the art breeding methodology and to exploit fully the breadth of genetic resources available. The project will focus on a small number of key characters not previously explored in depth and complementary to other ongoing European and national projects. These topics covered include disease and pest resistance, where in addition to marker development for major fungal and viral pathogens, a focus on emerging insect pests is planned. The impact of end-of-season drought and heat stress on the rhizobial symbiosis, and its consequences for plant performance, will be studied. Two characters that can influence grain legume yield, autofertility and number of flowering nodes, will be investigated. The potential for improving legume nutritional and organoleptic quality by identification of desirable traits and innovative selection methods will be investigated. LEGATO will conceive sustainable legume-based cropping systems adapted to different pedoclimatic zones, respecting local constraints. The project has been constructed around the participation of commercial partners including SMEs in the areas of marker development, plant breeding, and legume food processing, who will benefit from the advances made in these areas in LEGATO. Promising legume varieties and cropping systems will be tested at a series of pan-european sites to favour the widest possible take-up in agriculture, and the partners potentially concerned will participate in a stakeholder forum convened regularly during the project.

Results of line x tester analysis for 15 sunflower genotypes of the Agricultural Institute Osijek are presented in this paper. Three A lines (cms) and three Rf testers with different oil content level (low, medium, high) in all combinations (nine crosses) were crossed in 2010. In 2011, the lines, testers and their crosses were sown in field trials at two locations (Karanac and Osijek). The oil content was determined after harvesting, whereas line x tester analysis was conducted based on the obtained results. Variance of lines and testers, which refers to the general combining ability (GCA) was much higher than the variance of line x tester, related to specific combining ability (SCA). It showed on dominant role of the additive component of genetic variance in the inheritance of oil content. Statistically significant differences were not determined between the GCA and SCA effects. The highest values of GCA for oil content had line 2 (medium oil content) and tester 6 (high oil content) at both locations. The largest contribution for oil content had lines (57.81 and 51.28 %) followed by testers (28.88 and 26.27 %) and the lowest accounts for interaction (13.31 and 22.45 %) at both locations (Karanac and Osijek).

Effects of Azotobacter chroococcum inoculation on sugar beet production characteristics and microbiological status in the soil were studied on three different methods of sugar beet inoculation with Azotobacter chroococcum strains. The variety Drena was used in the study. Experiments were carried out at Rimski Šančevi in 2008, 2009 and 2010. Five strains of Azotobacter chroococcum were used as microbial inoculants. Three inoculation methods were applied: (A) strain incorporation into the soil before planting, (B) strain application on soil surface before the first inter-row cultivation and (C) seed inoculation before planting. All five Azotobacter chroococcum strains, in each of the three application methods, showed a positive effect on the production characteristics of sugar beet. The highest yield increases in root (6.45 t ha-1) and sugar (0.63 t ha-1) was obtained on seed inoculated with strain 10.

The aim of this study was to detect the most harmful weeds in the canopies of sugar beet during the years 1999-2009 in the Slovak Republic. The actual weed infestation was evaluated by a counting method per square. The four randomly established sample quadrants were situated minimally 20 m from field margin and apart each other, respectively. Temporal dynamics of all weed species in the canopies of sugar beet were statistically analyzed. In the sugar beet fields the most problematic weeds were: perennial weed (Cirsium arvense (L.) SCOP, Elytrigia repens (L.) DESV, Convolvulus arvensis (L.)), annual weeds (Chenopodium spp., Amaranthus spp., Atriplex spp., Persi- caria spp., Echinochloa crus galli (L.) Beauv., Datura stramonium (L.), Mercurialis annua (L.), Panicum capillare (L.), Iva xanthiifolia Nutt.) and cultural crops winter oilseed rape (Brassica napus (L.)). Temporal dynamics of actual weed infestation depend on climate conditions of production region, forecrop and canopy health con- dition. The most dangerous weed species were Persicaria spp., Amaranthus spp., Atriplex spp., Chenopodium spp. and Echinochloa crus galli (L.)P.Beauv, which infested more than 90% of sugar beet fields in maize and sugar beet production region.
