EVALUATION OF THREE CANOLA (BRASSICA NAPUS L.) CULTIVARS FOR YIELD AND SOME QUALITY PARAMETERS UNDER THE ENVIRONMENTAL CONDITION OF SOUTHEASTERN ANATOLIA, TURKEY

Abstract

. Canola is a significant alternate oilseed crop in Southeastern Anatolia, Turkey. While, there is no evidence for good yield potential canola cultivars are available in this area. Therefore, the study was conducted with three canola cultivars in consecutive two seasons (2013-14 and 2014-15) to find out the appropriate canola cultivars which are suitable to grow under the environmental condition of Southeastern Anatolia, Turkey. The experiment was carried out in a randomized complete block design with three replications. After two years of observation, it was found that plant height and branches plant-1 of all cultivars were varied significantly in both years. Considering the growing season, the maximum seed yield (2593.7 kg ha-1) was recorded in the first season (2014-15), while the minimum was recorded in the second season (2015-16). Among the cultivars, seed yield varied significantly and the maximum seed yield (2617.1 kg ha-1) was achieved in the variety ‘Licrown’. The variety, ‘Licord’ was produced the highest oil content (37.92%) and protein (22.48%), while, variety ‘Express’ achieved the lowest oil content (37.43%). The greatest palmitic acid (4.67%), stearic acid (2.06%) and oleic acid (65.5%) content were produced by the variety ‘Express’. While the variety ‘Licord’ produced the smallest value of stearic acid (1.86%), linoleic acid (17.17%). The variety ‘Express’ produced the lowest saturated fatty acid content (12.63%), while, the variety ‘Licrown’ achieved the highest (12.97%), although, the variety ‘Licrown’ produced the lowest (85.14%), and variety ‘Express’ produced the highest (85.47%) unsaturated fatty acid content. It is concluded that all cultivars have a good potential for the winter season of Southeastern Anatolia of Turkey. Accordingly, in the future the cultivar ‘Express’ could be used as a cultivar with high oleic and linoleic acid content and high yield under investigation conditions.
