Abstract

TSVETKOV, St., K. TSVETKOV, V. KONOV, I. VASSILEVA and P. BALEVSKA, 2004. Breeding and breadmaking quality of winter hexaploid triticale Mulei (X Triticosecale Wittmack) with complete rye genome. Bulg. J. Agric. Sci., 10: 53-56

A new original 42 chromosome triticale Mulei (x Triticosecale Wittmack) of complete rye genome was created via the methods of combinative breeding (6n x 6n) between Bulgarian (T-AD-106) and Mexican (AD Mexico F3 / 74) hexaploid triticales in the Dobroudja Agricultural Institute. Morphologically it resembles rye and refers to the rye type of triticale. Designed for cultivation at foothills "rye" regions being of poor and acid soils. Characterized by a complete resistance to powdery mildew and high resistance to rusts and smuts. Averaged for two years it outyielded wheat and rye with 13.3 % (+1000 kg/ha). Its breadmaking quality is nearly that of rye according to the physico-chemical grain characteristics. Mulei can be added or substitute rye for more grain and baking an worthy black rye bread.

Key words: triticale (2n=6n=42) of complete rye genome, productivity, physical and technological characteristics, breadmaking quality, rye addition or substitution
