Abstract
The association between genomic constitution and agronomic traits was studied in F<sub>2</sub> plants and F<sub>3:4</sub> families of two crosses between a winter hexaploid triticale line with a 2D(2R) chromosome substitution and two hexaploid triticale cultivars carrying the complete rye genome (BBAARR). The analyses revealed that 2D(2R) substitution reduces plant height and spikelet number per spike, increases the 1,000-kernel weight, does not reduce grain shrivelling, and promotes early heading and anthesis. 2D(2R) substitution lines exhibit deeper postharvest seed dormancy, which provides resistance to preharvest sprouting. However, 2D(2R) substitution lines are not recommended for winter hexaploid triticale cultivar development purposes due to their reduced grain productivity.
