영문 초록

This study was conducted to introduce the useful agronomic characteristics of rye into wheat. Primary triticale was obtained from a intergeneric hybridization between Triticum aestivum cv. Chugoku 81 and Secale cereale cv. Kyeonggi Jaerae. The somatic chromosome numbers of BC² F₁ populations which backcrossed with wheat two times to the primary triticale were ranged from 35 to 47. Rye chromosome di-addition wheat lines appeared the percentage of 3. 6 after the spontaneous selfing of mono-addition wheat lines and only 12. 7 percentages of these di-addition lines maintained same chromosome number to the next generation. The added rye chromosomes in pollen mother cell were easily eliminated during the meiosis. Rye chromosome addition wheat lines showed no distinct differences in morphology in comparison to wheat. It was considered that one rye chromosome, either mono or di-addtion, could not much effects to wheat phenotype.
