The primary purpose of this study was to determine factors influencing consumer preferences for UHT milk consumption in Erzurum province. The primary data used in this research was derived from Palandoken, Yakutiye and Aziziye districts of Erzurum province in 2010. The factor analysis was used to find out the factors affecting consumer preferences for UHT milk and to reduce these factors. As for the segmentation of consumers and bringing out the profile of each segment, cluster analysis was used. According to the results, 95.00% of households consumed UHT milk. 18 factors that are affecting the consumption of UHT milk were reduced to five main factors with factor analysis. The factor scores which determined with factor analysis were divided into three clusters by cluster analysis. UHT milk for consumers entering the first cluster has because of homogenous and packaging as well as intrinsic and extrinsic properties for advertising and price advantage is preferred. UHT milk for consumers entering the second cluster has ease of preparation and transportation, and confidential properties are preferred by reason.

Roumiana Dimova Vassilevska-Ivanova | Ira Stancheva | Maria Geneva | Zoya Tcekova
Interspecific cross was made between the common sunflower inbred line HA89 and an accession of wild Helianthus nuttallii (2n=2x=34) resistant to the most harmful disease complex and tolerant to drought and high temperature. The recombinant inbred line was a BC1F15 progeny. The most remarkable feature observed was the vigorous plant habit that manifests itself in measurable morphological characters such as increment plant height, stem diameter and diameter of the head. The line was non-branched (monocephalic) without anthocyanin pigmentation and possessed good agronomic characteristics. Along with the morphological and reproductive traits, some biochemical characteristics related to antioxidant activity were associated to wide hybridization. The overall characteristics of HA-Hnutt line make it a useful plant material for research on interspecific hybridization in Helianthus genus.

Nicola Galluzzo
Irish farms are predominately and highly specialized in crops as cereals, protein crops and in dairy productions. The aim of this research was to estimate the economic efficiency in Irish farms part of the Farm Accountancy Data Network (FADN) dataset stratified in function of their own typology of productive specialization since 2004 to 2015 by a quantitative approach such as the Data Envelopment Analysis (DEA). Positive has been the role of inputs as financial subsidies allocated by the Common Agricultural Policy, the first and second pillar, in increasing the economic efficiency of Irish farms. Field crops farms have not had the best results in terms of the economic efficiency even if over the time, in particular during the economic crises 2008-2009, findings have not been stable with significant fluctuations and a sharply decrease of efficiency as a consequence of economic turbulences. Focusing the attention on the research outcomes in all years of investigation comparing also the different typology of farming, mixed farms and farms with animals, such as specialist cattle, sheep, goats and other grazing livestock, have had the highest levels of economic efficiency equal to 100%; by contrast Irish dairy farms have had the modest levels of economic efficiency close to 77%.

Fusarium culmorum is predominating causal agent of head blight (HB) and root rot (RR) in cereals worldwide. Since F. culmorum has a great level of genetic diversity and the parasexual stage is assumed for this phytopathogen, characterization of isolates from different regions is significant step in food safety and controlling the HB. In this study, it was aimed to characterize totally 37 F. culmorum isolates from Turkey via sequence related amplified polymorphism (SRAP) marker based genotyping. MAT-1/MAT-2 type assay was also used in order to reveal intraspecific variation in F. culmorum. MAT-1 and MAT-2 specific primer pairs for mating assays resulted in 210 and 260 bp bands, respectively. 11 of isolates were belonged to MAT-1 type whereas 19 samples were of MAT-2. Remaining 7 samples yielded both amplicons. Totally 9 SRAP primer sets yielded amplicons from all isolates. Genetic similarity values were ranged from 39 to 94.7%. Total band number was 127 and PCR product sizes were in the range of 0.1-2.5 kb. Amplicon numbers for individuals were ranged from 1 to 16. According to data obtained from current study, SRAP based genotyping is powerful tool for supporting the data obtained from investigations including phenotypic and agro-ecological characteristics. Findings showed that SRAP-based markers could be useful in F. culmorum characterization.

Çalışma; kısa vejetasyon süresine sahip karabuğdayın Isparta koşullarında yazlık olarak farklı zamanlarda yapılan ekimi ile ilkbahar yağışlarından faydalanarak sulanmadan yetiştirilebilme olanaklarını araştırmak amacıyla yürütülmüştür. Araştırmada Aktaş karabuğday çeşidi kullanılarak, 1 Mart, 10 Mart, 20 Mart, 30 Mart, 9 Nisan ve 18 Nisan (kontrol) olmak üzere 6 Ekim zamanı tesadüf blokları deneme desenine göre 2015 ve 2016 yıllarında tarla çalışması olarak yürütülmüştür. 18 Nisan ekim zamanı kontrol olarak sulanmış, diğer ekim zamanlarında sulama yapılmamış, doğal yağışlara bağlı olarak yetiştirilmiştir. Denemede her iki yılda da 1 ve 10 Mart ekim zamanlarında çıkış olmuş, fakat çıkıştan sonra don zararı nedeniyle tüm bitkiler ölmüştür. Her iki yılda da (2015 ve 2016) bitki boyu, biyolojik verim ve tane verimine ekim zamanlarının etkisi istatistiksel olarak önemli olmuş ve en uzu bitki boyu sırasıyla 65,9 cm ve 60,0 cm, en yüksek biyolojik verim 427,3 kg/da ve 403,7 kg/da ve tane verimi 145,7 kg/da ve 132,8 kg/da ile 18 Nisan ekim tarihinde sulanan parsellerde belirlenmiştir. Her iki yılda da 1000 tane ağırlığı, hektolitre ağırlığı ve protein oranına ekim zamanlarının etkisi istatistiksel olarak önemsiz olmuştur. Isparta ekolojik koşullarında karabuğday ekonomik olarak ancak sulanarak yetiştirilmesi sonucuna varılmıştır.
