Abstract

Twenty-five varieties of common wheat (Triticum aestivum L.) and 25 durum wheat (Triticum durum Desf.) grown in the Western Canadian Co-operative Tests were studied at Morden, Manitoba, in 1964, for their resistance to natural infestation by a spider mite, Tetranychus sinhai Baker. Some of these were heavily infested whereas others showed no infestation. The differences were statistically significant. Generally, the commonly grown varieties, such as, Selkirk, Thatcher, Ramsey, Stewart were resistant, but some of the hybrid varieties, such as Sask. 6070, Q2331-5 under test were susceptible.
