Abstract: In order to gain knowledge of genetic diversity of Hexaploid Triticale introduced from International Maize and Wheat Improvement Center (CIMMYT), and provide reference for its effective use, diversities of agronomic and quality characters were analyzed for 111 Hexaploid Triticale germplasm in this study. The results showed that: the average coefficient of variation of six agronomic traits was 16.94%, the average diversity index was 1.96, diversity index of spikelets/spike, spike length and grain weight were higher than 2.00; average coefficient of variation of 10 quality traits was 8.60%, the average diversity index was 1.94, diversity index of water absorption, dough stability time were higher than 2.00. Agronomic and quality traits of 111 Hexaploid Triticale showed a greater difference, with a wealth of genetic diversity.
