Assessing Agronomic Traits and Yield of Different Rainfed Triticale and Wheat Genotypes with Supplementary Irrigation

To assess of grain yield and agronomic traits of triticale in comparison with wheat under supplementary irrigation an experiment was carried out during 2009-10 year in Qamloo dryland Research station located in Kurdistan. A split plot with RCBD arrangement in four replications was used. Moisture regimes including irrigation at planting time, irrigation at early grain filling and no irrigation (rainfed conditions) considered as main plots. Six genotypes including three genotypes of triticale (Juanillo and two promised lines) and three genotypes of bread wheat (Azar2 and two promised lines) were included as sub plots. Even though there was not significant difference between irrigation at planting time and rainfed conditions, irrigation at grain filling with grain yield of 3805 Kg/ha averagely produced 17.5 % over than them. However, triticale produced 26 %, 49% and 48 % more grain yield than wheat in irrigation at planting, milking and rainfed conditions, respectively. This superiority was related to better performance of triticale in yield components, biological yield, plant height and grain filling period.
