CROSSING EXPERIMENTS WITH TRITICALE

Abstract

Besides crosses between wheat and rye, crossability between hexaploid and octoploid Triticale was tested. F sub 1 hybrides as well as subsequent generations were examined. Octoploid Triticale F sub 1 showed no higher seed productivity than did the better parent. Even in subsequent generations an attempt to select suitable types for practical cultivation failed. Though hexaploid and octoploid F sub 1 plants produced considerably less seed than both parents, we succeeded in selecting valuable hexaploid individuals from subsequent generations. While for the past 14 years we were unable to improve our hexaploid Triticale No. 1 produced in 1952, hexaploid Triticale No. 30 produced from crossing Triticale of different degrees of polyploidy appears to be important for practical breeding. In this Triticale we succeeded in fixing the red color of the auricola characteristic of hexaploid wheat F 481.
