Study on the Translocation of Wheat- E. elongatum by Fluorescence in Situ Hybridization

Elytrigia Desv. is the third gene source. It has always been as highly valued as it used to be in wheat's breeding and genetic improvement. By using wheat chromosome engineering and establishing its heterology translocation, it will be a effective way which the excellent properties are improved into wheat. Some species from Aegilops have gametocidal gene. Variety types of chromosome structural variation can be induced high frequency by the not fully gametocidal function, and chromosome translocation and deletion will be produced. This variation are high frequency, directionally, stability. In this paper, by using ChineseSpring- Ae.cylindrical-2C disomic addition to cross with ChineseSpring- E. elongatum 7E (2n=14EE), the translocation and deletion of ChinesesSpring-E. elongatum 7E were induced. And by using Fluorescence In Situ Hybridization technique, the materials with translocation and deletion were identified. It showed that it is a important method which useful genes are transferred into wheat by using wheat and some translocation and deletion of it's kindred genus by Fluorescence In Situ Hybridization.
