Summary

A total of 700 wheat accessions of the Gatersleben gene bank were screened for gibberellic acid insensitivity genes (Gai) by a modified method. It was found, that 77 hexaploid and 5 tetraploid wheats were GA3-insensitive. The probable origin of theGai-genes is discussed.

Zusammenfassung

700 Sorten bzw. Linien der Weizenkollektion der Gaterslebener Genbank wurden unter Verwendung eines modifizierten Testverfahrens auf das Vorhandensein bzw. Fehlen von Gibberellinsäureinsensitivitätsgenen (Gai-Gene) geprüft. Dabei zeigte sich, daß 77 hexaploide und 5 tetraploide Weizen gegenüber GA3 insensitiv waren. Die vermutlichen Herkünfte derGai-Gene werden diskutiert.

Краткое содержание

С помощью усовершенствованн ого метода контроля было проверено 700 сортов или линий пшениц из коллекции пшениц гатерслебенского генного банка на присутствие или отсутствие генов (Gai-гены), нечувствительных к гиббереллиновой кислоте. При ¶rt;том было установлено, что 77 гексаплоидных и 5 тетраплоидных пшениц были нечувствительны к GA3. Обсуждается предполагаемое происхождениеGai-генов.
