METHOD FOR DISCRIMINATING EAR FORM AND SCAB RESISTANCE, AND METHOD FOR IMPROVING BARLEY PLANT USING THE METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method for specifically and efficiently discriminating a two-row nature or a six-row nature and scab resistance associated with a two-row- or six-row-natured gene for a barley plant.

SOLUTION: Using a backcross separation generation of a two-row-natured barley variety and a six-row-natured barley variety, the row nature of these individuals is discriminated accurately. As a result, the row nature is found to represent monogenic control. By using a molecular marker associated with the gene, it is found that six-row nature or two-row nature can be discriminated for an examined barley plant. Further, by using the molecular marker, it is supposed that scab resistance associated with the tow-row- or six-row-natured gene can be discriminated.
