Variation in Hay Yield and Quality of New Triticale Lines
Abstract
Objectives of the present study are to determine the variations in forage yield and quality of new triticale lines developed by cross-breeding methods and to develop better lines with superior characteristics over the current ones. Experiments were carried out in randomized complete block design with 3 replications during the cropping years of 2011-2012 and 2012-2013. A total of 5 cultivar and 20 lines were used as the plant material of the experiments. Genotypes were harvested at milk stage and their herbage yield, hay yield, crude protein yield and chemical composition were investigated. Twoyears average results revealed that herbage yields varied between 36.44-48.47 t ha-1, hay yields between 12.77-18.68 t ha-1, crude protein yields between 1.02-1.80 t ha-1, acid detergent fiber (ADF) between 32.92-44.63%, neutral detergent fiber (NDF) between 63.72-78.47%, crude ash ratios between 5.06-7.87%, crude protein content between 6.21-11.36%, dry matter digestibility (DDM) between 54.14-63.25%, dry matter intake (DMI) between 1.528-1.881 and relative feed value (RFV) between 64.18-89.31. Current results revealed superior characteristics for new triticale genotypes developed with cross-breeding over the current standard lines with regard to investigated parameters. It was concluded that cross-breeding yielded positive outcomes and therefore, currently investigated high-yield and quality lines should be prepared for registration
