    (Serbian Genetics Soc, 2015) Pinar, Hasan; Ercisli, Sezai; Unlu, Mustafa; Bircan, Mustafa; Uzun, Aydin; Keles, Davut; Baysal, Filiz
    More recently the use of different molecular markers in fruit species to determine particularly genetic diversity, genetic relationships and cultivar identification has been gained more importance. In the study, 13 randomly amplified polimorfic DNA (RAPD) and 4 inter-simple sequence repeat (ISSR) markers were used to evaluate genetic relationships among 95 almong accessions (26 foreign cultivars and 69 national cultivars and selections). The all plant material found in Almond Germplasm Repository in Gaziantep, Turkey. Both RAPD and ISSR markers distinguished the almond cultivars and selections in various levels. 17 RAPD and ISSR markers yielded a total of 73 scorable bands, which 51 are polymorphic. The two marker system exhibited variation with regard to average band sizes and polymorphism ratio. The average polymorphism was higher in ISSR (88%) compared to RAPD (74%). RAPD and ISSR marker systems were found to be useful for determining genetic diversity among almong genotypes and cultivars. Combining of two dendrograms obtained through these markers show different clustering of 96 almond specimens without geographical isolation. These results supported that almonds in Turkey indicated considerable genetic diversity.

    Distribution of Water Loss via Evapotranspiration in a Pistachio Tree Orchard under Drip Irrigation and Non-Irrigation Conditions
    (Czech Academy Agricultural Sciences, 2015) Ozmen, Selcuk; Kanber, Riza; Steduto, Pasquale; Unlu, Mustafa; Aydin, Yusuf; Diker, Kenan
    The present study aimed to measure the distribution of water loss via evapotranspiration (ET) in a pistachio tree orchard under drip irrigation and non-irrigation conditions at the experimental orchard of the Pistachio Research Institute, Gaziantep, Turkey. The experimental design consisted of a 10 x 10 m(2) grid system constructed of PVC pipes spaced 2 in apart (horizontally and vertically) that was placed around each tree for the drip irrigation condition (water applied every 7 days) and the non-irrigated condition. Moisture content was measured using the neutron scattering method for both treatments. Water loss via ET was estimated based on the soil water balance method, which included measurement of soil moisture, precipitation, and irrigation. Total water loss via ET under drip irrigation conditions was 518 mm vs 220 mm under non-irrigated conditions. Water loss via ET for the total soil profile and individual layers under non-irrigated conditions was higher at the four outer corners of each 10 x 10 m(2) grid than under irrigated conditions. Moreover, water loss via ET was the highest at the grid system pipes closest to the two laterals under irrigation conditions. In addition, the total percentage of water loss via ET was the highest at the 60-80-cm and 20-40-cm soil layers under drip irrigation and non-irrigation conditions, respectively, and the total percentage of water loss via ET was the lowest at the 40-60-cm and 0-20-cm soil layers under drip irrigation and non-irrigation conditions, respectively. Lastly, it could be considered that root density increased as water loss via ET increased.

    Irrigation Rationalization Boosts Wheat (Triticum aestivum L. Yield and Reduces Rust Incidence under Arid Conditions
    (Hindawi Ltd, 2021) Alghawry, Adnan; Yazar, Attila; Unlu, Mustafa; Colak, Yesim Bozkurt; Iqbal, Muhammad Aamir; Barutcular, Celaleddin; El-Ballat, Enas M.
    Under changing climate, water scarcity and frequent incidence of diseases like stripe rust pose the biggest threat to sustainable crop production which jeopardizes nutritional security. A study was executed to rationalize crop water requirement and evaluate wheat (Triticum aestivum L cv. Bohoth 3) yield losses by stripe rust infection under irrigated conditions. Seven water treatments included three irrigations in three stages/season (S-3), four irrigations (S-4), and five irrigations (S-5) at the different sensitive growth stages, full (F), and two deficit irrigation levels including D-1 = 80% of field capacity (FC) and D-2 = 70% (FC) along with farmers' practice of irrigation as control (C). Results revealed that F and D I boosted grain yield by 31 and 14%. Overall, F irrigation regime resulted in the highest grain production (2.93 ton/ha) as well as biomass yield (13.2 ton/ha). However, D-2 had the highest value of grain protein (15.9%) and achieved the highest application efficiency (AE) at midseason (54.6%) and end season (59.6%), and the lowest AE was under S-3. Also, halting irrigation at the milky stage (S-5) led to a significant decrease in irrigation water use efficiency as compared to D-1. However, cutting irrigation at the end of seedling, heading, and milky stages (S-3) caused a significant reduction in E., crop water use (ET.), and 1000 grain weight in comparison with all other treatments. Regarding yellow rust, S-3 irrigation regime resulted in the lowest incidence of yellow rust infection. The highest irrigation and water use efficiency values were recorded under D-1 (0.79 and 0.59 kg/m(3)), and the lowest values were obtained for control. Hence, the deficit irrigation treatment D, could be recommended as the best appropriate strategy to save more water and to improve the water productivity under Yemeni agrodimatic conditions.
