Abstract

The invention relates to a cultivating method of a wheat-agropyron elongatum FHB (Fusarium head blight)-resistant 7E chromosome long arm translocation line. The cultivating method comprises the following steps: processing F2-generation seeds obtained by hybridizing a wheat-agropyron elongatum 7E substitution line and Yangmai 16 by <60>Co radiation, and in a propagation process of radiated offspring, firstly, performing field FHB resistance screening to select individual plants which are high in FHB resistance and have related features of agropyron elongatum; and based on this, detecting the obtained individual plants by using an agropyron elongatum 7E chromosome long arm specific marker, and finally, confirming the wheat-agropyron elongatum FHB-resistant translocation line by virtue of cytology. By combining field phenotype screening, molecular marker identification and cytology confirmation, the wheat-agropyron elongatum FHB-resistant 7E chromosome long arm translocation line is created; the obtained FHB-resistant translocation line provides a new germplasm or base material for wheat variety improvement and genetic research, and can be used as a parent to participate in cultivation of the FHB-resistant wheat.

Description

technical field [0001] The invention belongs to the field of crop genetics and breeding, and this research utilizes 60 Co (cobalt 60) radiation treated the F2 generation seeds of wheat-Ethiopyra elongatum 7E substitution line (DS7E / 7B) crossed with Yangmai 16. During the reproduction process of the irradiated offspring, the resistance to head blight in the field was screened first. Individual plants with better resistance to scab and E. elongatum characteristics were selected for planting. On this basis, the selected individual plants were detected by using the specific marker on the long arm of chromosome 7E of E. elongatum. Finally, wheat- Confirmation of translocation line resistant to head blight of E. elongatum. Using the combination of field phenotype screening, molecular marker identification and cytological confirmation, a wheat-Thinopyrum elongatum resistance to head blight 7E chromosome long arm translocation line was established. Background technique [0002] 1 ...
