Abstract: The present application discloses a method for rapidly identifying the resistance of wheat to black point disease caused by Bipolaris sorokiniana, where testing takes places in an indoor, controlled environment. The test method includes surface sterilization of wheat seeds, and cultivating wheat seedlings from the sterilized wheat seeds; preparing conidial suspension of Bipolaris sorokiniana, and spraying the conidial suspension on the seedlings at one-leaf-one-shoot stage; recording the percentage of the diseased leaf area in total leaf area of the first leaf of the wheat seedling on the 10th day of inoculation; calculating the black point incidence of the wheat according to an equation, and then evaluating the resistance of wheat to black point disease caused by Bipolaris sorokiniana through the black point incidence.

Abstract: According to one embodiment, a connector fixing structure includes a printed circuit board assembly, and a base to which the printed circuit board assembly is attached. The printed circuit board assembly has a connector mounted on a printed circuit board, and a connector panel attached to the printed circuit board. The connector has a connector main body, a front flange projecting from the connector main body, and a rear flange projecting from the connector main body. The connector panel has a provisional fixing portion which is inserted between the front flange and the rear flange and provisionally fixes the connector to the connector panel. The base has a fixing portion which is inserted between the rear flange and the connector panel, thereby brings the front flange into contact with the connector panel and fixes the connector to the base, when the printed circuit board assembly is attached to the base.
