Comment	Ne2 was stated to be absent or rare in tetraploid wheats (764). The Chinese Spring 2BS telosome carries an Ne2 allele that is not present in Chinese Spring (762). A unknown Ne2 allele (376) is present in the hexaploid stock Harvest Queen (391) and in the tetraploid stocks Acme (376), Arnautka (376), Carleton (376), Langdon (1093), Mindum (376) and Stewart (376).
