영문 초록

This experiment was carrid out to study the relationship between the seed size and chromosome number in winter primary octoploid triticale. Total of 147 plants of advanced winter primary octoploid triticale have various chromosome numbers from 2n=40 to 57. The frequency of euploid was 38.1%, whereas the frequency of various aneuploids was much higher ; 2n=55 (22.4%), 2n=54 (13.6%), 2n=53 (10.9%) and 2n=52 (9.6%) including 2 hyperaneuploids (2n=57 ; 1.3%). Of 91 aneuploid plants, 89 plants were the hypoaneuploids, and it was 98.7% of a total aneuploids. Most of hypoaneuploids had 2n=52 to 55 chromosomes and it covered 82.0% of a total hypoaneuploid plants. The relationship between seed size and chromosome numbers were indicated that the long size of seeds generally had more chromosome numbers than that of the short size, while the intermediate showed a wide range from 45 to 56.
