Grain yield and some quality properties of triticale genotypes

Triticale is used for different targets as human food and animal feed in the world. In particular, Triticale is an important alternative crop to use of marginal areas and to overcome the shortage of rising feed. This study was carried out for three years between 2012 and 2015 to determine the yield and quality aspects of triticale genotypes in Yozgat ecological conditions. Experiments were carried out in randomized complete block design with four replications. As a result of the variance analysis, year, genotype and year × genotype interactions were found to be significant in terms of all traits examined. According to the results including years averages; plant height, the number of spikes per square meter, harvest index, grain yield, thousand grain weight, hectoliter weight, crude protein content, crude fat content, starch content, ash content, acid detergent fiber (ADF), neutral detergent fiber (NDF) value, Zeleny sedimentation value, wet gluten, K, P and Mg were found between 84.1-107.6 cm, 288.0-508.7 no, 28.6-38.8 %, 230.4- 366.1 kg da-1, 29.0-40.3 g, 66.7- 71.3 %, 12.3-14.8 %, 1.11-1.76 %, 62.2-66.2 %, 1.68-2.17 %, 2.437-3.585 %, 17.5-19.1 %, 20.3-30.9 ml, 22.4-26.5 %, 0.525-0.668 %, 0.129-0.150 % and 0.366-0.408 %, respectively. The highest grain yield was obtained from numbered 14 (351.7 kg da-1), 15 (359.7 kg da-1), 23 (340.2 kg da-1) and 24 (366.1 kg da-1) triticale genotypes. Positive and significant correlation was found for plant height (r=0.422**), number of spikes per square meter (r=0.405**), harvest index (r=0.548**), 1000-grain weight (r=0.479**), hectoliter weight (r=0.559**) and P (r=0.129*) with grain yield. protein content (r= -0.238**), crude fat content (r= -0.126*), ADF (r= -0.119*), NDF (r= -0.566**), Zeleny sedimentation value (r= -0.304**) and wet gluten (r= -0.496**) showed negative correlation with grain yield. According to the Biplot analysis graph, the 23 numbered genotype with high grain yield also appeared to be in the foreground in terms of properties such as plant height, 1000-grain weight, Zeleny sedimentation value, wet gluten, protein content, K, P and Mg. For grain yield, genotype 7 had good adaptation to all environments, genotypes 3, 4, 9 and 21 had moderate adaptation to good environments
