MALTING QUALITY OF HEXAPLOID TRITICALE IN COMPARISON WITH THAT OF BARLEY, WHEAT AND RYE

Malting quality of hexaploid triticale (x Triticosecale Wittmack) was analysed in comparison with that of barley as a standard, and wheat and rye as parental species, by using the micro-malting method. Triticale malt had higher diastatic power than rye and wheat, and was particularly higher than barley. Malt extract and extract yield of triticale were almost as high as the levels for rye, while those of barley were rather low. An average value of total malting loss obtained from 11 cultivars of triticale was lower than that of hexaploid wheat and malting loss from shoot and root was lower than that of barley and hexaploid wheat. Total and soluble nitrogen were high in triticale. Steeping period of triticale was shorter than that of barley by about four-fold. The high diastatic power, high malt extract, and short steeping period in triticale malt seemed to be advantageous industrial brewing characteristics, while high total nitrogen and low germination capacity appeared to be disadvantageous.
