Inheritance of Antioxidant Activity of Triticale under Drought Stress

A.H. Gorji, Z. Zonoori, M. Zolnoori and A. Jamasbi

The objective of this study was to evaluate the inheritance of antioxidant activity of triticale under drought stress. For this study, the F1 seeds of a 7x7 half diallel along with their parents were grown in greenhouse in well watered and drought conditions. For this purpose, seven selected lines from breeding programs conducted previously were used as plant entries of the research. Yield and yield components were taken up to determine the best lines to be candidate for future varieties. After exposure of plants to drought stress, Catalase (CAT), the activity of Ascorbate Peroxidase (APX) and Superoxide Dismutase (SOD) enzymes were measured. Presence of over dominance and greater importance of dominance effects in control of traits was observed. All of traits had very high broad sense heritability. In stress condition among the traits APX had high narrow sense heritability (Hn), followed by moderate Hn for CAT and low Hn for SOD and in normal condition APX had highest Hn, followed by SOD with moderate Hn and CAT with low Hn. Regarding to the significant correlations between drought tolerance and antioxidant activity in the literature and considering the highest heritability of antioxidant enzymes in this experiment, it can be inferred that they can be considered as good yardstick for selecting resistance to drought in triticale.
