AC Ultima spring triticale

Abstract

AC Ultima, a spring triticale cultivar (X Triticosecale Wittmack), is widely adapted to the Canadian Prairies. AC Ultima represents an improvement in Hagberg Falling Number, which is usually associated with improved harvest-time sprouting resistance. AC Ultima expressed high grain yield, early maturity, heavy kernels and excellent lodging resistance compared to the check cultivars. AC Ultima is very resistant to the prevalent races of leaf rust, stem rust, and common bunt and resistant to common root rot. AC Ultima is eligible for the grades of Canada Triticale.
