Malting qualities of eleven hexaploid triticale cultivars (X Triticosecale WITTMACK) with different chromosome constitution of R-genome, types of cyioplasm and winter/spring growth habit were evaluated by using micromalting trials. Cultivars with complete type for R-genome chromosomes had higher diastatic power, malt extract, and extract yield than those of the substitution type. Cultivars with Triticum aestivum cytoplasm used in this experiment had more number of R-genome chromosomes replaced by D-genome chromosomes, and they showed comparatively low diastatic power and extract yield in the malt. Higher diastatic power was found in cultivars with Triticum turgidum cytoplasm than with aestivum cyioplasm, while higher malt extract and extract yield were observed in cultivars with aestivum cytoplasm than with turgidum cytoplasm. Winter-type triticale, Lasko, showed much higher values in diastatic power, malt extract, extract yield and germination capacity than those of the spring-type triticale in this experiment. Generally, cultivars with complete type of R-genome chromosomes and aeslivum cytoplasm had higher malt extract, extract yield, and Kolbach index, and lower total nitrogen content than those with substitution type in R-genome chromosomes and turgidum cytoplasm. Total nitrogen content was assumed to correlate with the level of modification and enzyme activities of hexaploid triticale malt.
