Effect of chromosomes of the wheat D genome on traits of hexaploid substitution triticale
The D genome of wheat (Triticum aestivum cv. Panda) was used in this study to improve traits of hexaploid winter triticale (×Triticosecale Wittmack). Genome D expression was studied in hexaploid triticale lines with single substitutions (1D/1A, 3D/3A, 4D/4A, 5D/5A, 6D/6A, 7D/7A) and a line with 4 substitutions (1D/1A + 3D/3A + 4D/4A + 6D/6D). Chromosomes 1D and 3D have introduced to the analysed substitution lines resistance to wheat leaf rust (Puccinia triticina, synonym P. recondita f. sp. tritici) and resistance to preharvest sprouting (which is very important in hexaploid triticale), reflected in a high expression of seed dormancy, a high falling number, and low alpha-amylase activity in grain
