Abstract:

Twelve buffelgrass genotypes were used in this experiment to evaluate them for their productivity and water use efficiency under four irrigation intervals (2, 4, 6 and 8-days). Expanding the irrigation interval decreased plant height and dry matter yield, while, increased water use efficiency. The introduced cultivar Biloela had superior performance for plant height, dry matter yield, water use efficiency under all irrigation treatments, while accession ALG was vice versa. Based on total forage yield, insignificant differences were recorded among local accessions UIO, BUR-2, ZIL, UIA and RIY-3 and ranked in second order after cultivar Biloela. Local accessions BUR-1, BUR-2, ZIL, RIY-2 and RIY-3 had low drought susceptibility index (DSI<1) in all cases, and can be labeled as drought–tolerant genotypes. Moreover, The BeDREB gene was present in all buffelgrss genotypes except genotype ALG. This genotype also recorded the lowest values of water use efficiency.
