304 DETERMINATION OF YIELD AND YIELD COMPONENTS OF SOME CRAMBE GENOTYPES IN THE WORLD CRAMBE COLLECTION Orhan KURT, Tuba ÖZYILMAZ, Merve GÖRE University of Ondokuz Mayis, Faculty of Agriculture, Department of Field Crops, 55139 Atakum/Samsun, Turkey Corresponding author email: merve.gore@omu.edu.tr Abstract This research was carried out in Samsun ecological conditions, 2016-2017 summer seasons. This study was conducted to determine the yield and some agricultural characteristics of some Crambe hispanica subsp. abyssinica genotypes in the World Crambe Gene Pool, which are the basis for adaptation. In the study, 71 crambe genotypes were evaluated. Research result: the length of the plant is between 51.9 and 90.7 cm; number of branches per plant is between 4.1 and 9.5; the number of seeds per plant is from 57.4 to 376.6; 1000 grain weight was found to vary between 5.13 and 12.24 g and grain yield per plant varied from 0.421 g to 2.717 g. The result of the research: it has been determined that the genotypes evaluated have a superior performance in terms of the characters evaluated in total 13 genotypes including 2, 7, 8, 16, 30, 34, 41, 44, 49, 51, 61, 65 and 66 genotype. As a result, it has been decided that these genotypes can be used as a genitor in the development of crambe varieties suited to the Samsun ecological conditions. Key words: Crambe, Crambe abyssinica Hochst, agricultural characters, yield. INTRODUCTION Crambe of the Brassicaceae family is originated from the Iranian-Turanian and Mediterranean regions of South-West Asia (Knights, 2002; Özyılmaz et al., 2017). Crambe seeds contain 35-60% oil, 20-40% protein and 12.3% crude fiber. After the oil is removed, the remaining oil cake contains 47.6% fat and 31.6% protein (Van et al., 1990). Crambe is not considered edible oil because it contains high erusic acid. Crambe oil is used in many industrial area such as lubricants, adhesives, plastics, textile industry, synthetic rubber, printer ink, detergent, perfume and motor oil. In addition, crambe is used as an alternative plant in the production of biodiesel, as a renewable energy source. Therefore, crambe is an important plant that contributes to reducing the global warming problem and reducing air pollution caused by fuels (Li et al., 2010). New oil plants, such as cramble, have to be incorporated into the production system, which is suitable for multipurpose use in order to increase vegetable oil production. When considering climate and soil requirements, there is no factor that prevents the inclusion of crambe plant, which has high adaptability ability, into the agricultural production system. To be included in our agricultural system of crambe plant adaptation experiments in different ecological regions of Turkey must be done. It is extremely important that the suitable crambe genotypes that are eventually identified at the end of these adaptation experiments are introduced into the farm. For this reason, this research was carried out to determine the yield and some yield components which will be the basis for the adaptation of the crambe genotypes in the "World Crambe Gen Collection" to the Samsun ecological conditions. MATERIALS AND METHODS This research was conducted in the Samsun Province, Alaçam District, Geyikkoşan location. The altitude of the experimental area is 4 meters. The soil structure is clay, lime, salt- free, pH is slightly alkaline, organic matter is moderate, phosphorus level is medium and potassium level is high. When the climate data are evaluated as the experiment season and the multiannual average for the experiment area, the data are the followig: the average relative humidity and monthly precipitation during the Scientifc Papers.
