TSVETKOV, St. M. and K. S. TSVETKOV, 2003. Winter triticale cv. Satellite (2n=6x=42) – an original variety with solid stem resistant to Cephus pygmaeus L. Bulg. J. Agric. Sci., 9: 329–334
Winter triticale Satellite (2n=6x=42) with solid stem originated from the complex cross (MBX-11-7 x T-AD-17-B) x AD-No11. The female parental form MBX-11-7 was common wheat (T. aestivum L.) with solid stem developed through interspecific hybridization between T. aestivum L. (hollow stem) and T. durum Desf. (solid stem). The male parental forms T-Ad-17-B (General Toshevo) and AD-No11 (CIMMYT, Mexico) were secondary triticales with short hollow stem and high productivity. According to its systematic affiliation triticale cv. Satellite belongs to the 42-chromosome wheat type triticale (X Triticosecale Wittmack). It possesses high productivity and exceeded common wheat cv. Sadovo 1 with 9.2 %, and field triticale cv. Lasko with 9.9 %, averaged for two years. It has maximum stem solidness at all its internodes. It demonstrated high resistance to damages caused by Cephus pygmaeus L., wheat and hollow-stemmed rye being highly susceptible to this pest.
