Isogenic Lines을 利用한 小麥品種의 春播性遺伝子 分析 第Ⅲ報 主要育成品種의 春播性遺伝子 究明 = Genetic Analysis of Spring Growth Habit in Wheat (Triticum aestivum L.) Using Isogenic Lines Ⅲ Identification of the Genes for Vernalization in the Major Korean Wheat Cultivars

다국어 초록 (Multilingual Abstract)

This experiment was conducted to clarify the genetic nature for vernalization gene using isogenic tester lines with Vrn1, Vrn2, Vsn3 and Vrn4 respectjvely, and for lateness gene in the major Korean wheat cultivars, which are used in breeding program for early maturity. Wheat cultivars, Suweon 210, Cheonggemil and Chugoku 81 were determined to carry two dominant Vrn genes such as ; Suweon 210 had Vrn 3 and Vrn 4 ; Cheonggemil had Vrn 2 and Vrn 4 ; Chugoku 81 had Vrn1 and Vrn4, Milyang 11 had one Vrn4 gene and Geurumil did not have any Vrn gene at all. Olmil appeared to possess no-known Vrn genes so far identified but has an additional Vrn for vernalization. This new gene may be different from the known Vrn1, Vrn2, Vrn3 and Vrn4. A recessive gene for lateness (P) which is independent from Vrn genes was identified in Suweon 210, Cheonggemil, Milyang 11, Chugoku 81 and Olmil. This new gene was determined to prolong to days of flag leaf emergence which required 20-day vernalization period.
