Using Biplot Analysis Technique to Selection in Tritikale Breeding Studies

This study was carried out in Diyarbakır conditions with 20 advanced triticale lines and 5 standard varieties 2012-2013 2013-14 growing seasons. According to variance analysis results, the interaction of year, genotype year*genotype found be significant (p<0.01; p<0.05) terms many characteristics. results showing that plant height changed 3 237-5 389 kg/ha-1, hectoliter weight is 71.2-78.8 kg/hl-1, thousand grain 28.0-40.2 g, protein content 14.6%-17.2%, moisture rate varied between 7.9-8.1%. In traits, used research were superior as experiment. addition, genotypes determined by considering all characters together GT biplot technique. technique, PC1 made up 36.83% variation, PC2 constituted 19.53% variation 56.36% total. research, depending on ecological factors seasons, plants earlier spiked reached higher first year; It yield, than second contrary, lower year due high precipitation. concluded techniques facilitate work breeders selection. has been a single season will insufficient two seasons may sufficient evaluate cultivar candidates.
