Evaluation of Durum Wheat (Triticum durum Desf.) Genotypes Originated from Southeast Anatolia Region for Some Agricultural Character

Abstract

This study was conducted to determine some agricultural properties of some local durum wheat (Triticum durum Desf.) genotypes, belonging to Southeast Anatolia Region, compared to modern cultivated varieties. In the study, 21 standard durum wheat genotypes and 4 standard varieties were used as plant material. The study was carried out in Kiziltepe district of Mardin province in 2013-2014 and 2014-2015 growing seasons. The genotypes used were evaluated for some morphological and physiological parameters. According to two-year average data; the differences between genotypes and years were found to be statistically significant, whereas genotype x year interaction was found to be insignificant in all of the characters. Grain yield ranged between 201-347 kg da-1; spike number was 190-349 spike m-2; grain number per spike was 20.83-38.80 grain spike-1; and spike length was between 6.33-10.08 cm, respectively. There were statistically significant differences between the varieties in terms of normalized vegetation index (NDVI), chlorophyll content (SPAD value), leaf area index (YAI) value, vegetation temperature (BOS) values which are accepted as physiological parameters. According to the results of correlation analysis, statistically significant and high correlations between grain yield (GY), number of spikes m-2 and biological yield (biomass), and between LAI value, SPAD value and NDVI values were found.
