Evaluation of some Quality Characteristics in Durum Wheat (Triticum durum L.) Genotypes Grown under Rainfed and Irrigated Conditions by Mixograph Device

Abstract

In this study some quality characteristics and mixograph parameters of some durum wheat (Triticum durum L.) varieties and advanced lines were investigated and the relationship between them was determined. The material used in the study was grown in rainfed and irrigated conditions in 2016-2017 growing period at Bahri Dağdaş International Agricultural Research Institute. Some physical, chemical and rheological properties of durum wheat samples as well as some mixograph parameters (peak time (PT), peak height (PV), right peak slope (RPS), final peak width (CT), peak area (TINT) area (TTINT) and mixograph scale (MS) were examined. When durum wheat samples were evaluated in terms of MS which is an important indicator of gluten strength, Eminbey (7.5), Meram (6.0) and Selçuklu (5.25) varieties were found above the average (4.38). Positive correlation was obtained between PT and SDS (0.862), DDT (r=+0.791), STB (r=+0.862); and negative correlation was obtained between DS12 (r=-0,848). Positive correlation was obtained between PV and SDS (r=+0.654), DDT (r=+0.425) and STB (r=+0.483). Positive correlation was obtained between CT and SDS (r=+0.820), DDT (r=+0.681) and STB (r=+0.824) TINT and SDS (r=+0.855), DDT (r=+ 0.726) and STB (r=+0.853) and significant at p<0.01, statistically. In this study, with the use of a mixer, a small amount of sample was obtained in a short time about the quality of durum wheat. However, this subject will contribute to the use of mixograph device in durum wheat with further studies.

Using Mixograph Parameters and Some Quality Properties in Selection of Durum Wheat Genotypes

“…Mixograph development time ranged between 1.55 and 3.67 min in terms of location means. In parallel study, similar results were obtained and it was determined that the mixograph development time of some durum wheat ranged between 1.54 and 3.77 minutes (Demir et al, 2019). Line 7 (3.79 min) had the highest value in examined lines and Eminbey (3.67 min) had the highest value in examined varieties (Table 3).…”

“…Aydoğan et al (2012) found that the mean protein content of 5 durum wheat varieties was 13.89% in irrigated conditions during 2009-2011. In a similar study, the average protein content of 9 different durum wheat was 12.57% (Demir et al, 2019). SDS sedimentation: SDS sedimentation (SDSS) is an important parameter that gives an idea about gluten strength in durum wheat quality breeding (Brites and Carrillo, 2001).…”
