영문 초록

The non-waxy rice variety IR54, which shows extremely late heading in Korea, was backcrossed four times to the waxy rice variety Suweon 290, which shows medium heading. In every backcross generations, the heterozygous plants for waxiness were selected and the recurrent parent IR54 was backcrossed to these selected heterozygous plants. The BC₃F₄ and BC₃F₄ population segregating in waxiness and heading days were grown in field conditions in 1985 and in 1986 respectively. The extremely late heading was proved to be single recessive character. Close linkage was found between the extremely late heading and non-waxiness. The recombination value between the locus for the extremely late heading and the wx-locus was calculated as 6.7% in the BC₃F₃ and 11.1% in the BC₃F₄ generation.
