Isogenic Lines을 利用한 小麥品種의 春播性遺伝子 分析 第Ⅰ報 主要品種의 播性程度分類 및 春播性遺伝子 確認

Genetic Analysis of Spring Growth Habit in Wheat (Triticum aestivum L.) Using Isogenic Lines Ⅰ. Classification of the Degree of Vernalization Requirement and Reconfirmation of Vernalization Genes of Isogenic Tester Lines

These experiments were carried out, to classify the degree of vernalization requirement and to reconfirm the genes for vernalization of the isogenic tester lines of Triple Dirk, each of which are known to carry a single dominant gene for vernalization, namely Vrn l, Vrn 2, Vrn 3, and Vrn 4, respectively. 1. The degree of vernalization requirement, designated as I, II, III and IV of elevev wheat cultivars was classified : Pavon 76 as I; K 15, Bb-cal, Tesia 79 and Imuris 79 as II; Suweon 210, Cheonggemil, Milyang 11 and Chugoku 81 as III ; Geurumil, as IV. 2. Isogenic lines of Triple Dirk, known to carry each of Vrn 1, Vrn 2, Vrn 3 and Vrn4, respectively, were confirmed that each tester lines carries a pair of dominant gene for spring growth habit.
