Abstract: This invention intends to develop many DNA markers for a plant of the genus Fragaria and detect powdery mildew resistance with high precision by using the many DNA markers. The marker associated with powdery mildew resistance in a plant of the genus Fragaria comprises a continuous nucleic acid region sandwiched between the nucleotide sequence as shown in SEQ ID NO: 1 and the nucleotide sequence as shown in SEQ ID NO: 19 in the chromosome of the plant of the genus Fragaria.

Abstract: A radio communication device for data communication with another terminal through wireless medium, includes: a communicator which transmits/receives data by predetermined data communication units; a communication meter which measures a data communication unit which is actually communicated for a predetermined period in the communicator; and a controller which finds an average unit length of the data communication for the period on the basis of a measure result in the communication meter so as to obtain communication load information based on the average unit length.

Abstract: PER when a wireless apparatus is connected with a predetermined wireless access point is estimated on the basis of three parameters of the received signal strength, the interference signal strength, and the interference adjacency, which have been transmitted from the wireless access point, then the communication throughput is calculated by using the estimated PER, and the connection with a wireless access point expected to have highest communication efficiency is performed. As a result, it is possible to select a wireless access point having high communication efficiency with good precision, as compared with a method, in the related art, of simply performing a connection with a wireless access point having high received signal strength or a method of simply performing a connection with a wireless access point where an interference wave is strong.
