Further sources of field resistance to crown rot (Gibberella zeae) of cereals in Queensland

Abstract

Four hundred cultivars and lines of wheat, five cultivars of oats, and two of barley were examined for resistance to crown rot (Gibberella zeae) in field trials over the period 1965-1969. Field resistance was confirmed in the wheat cultivars Gala and Mengavi ; resistance comparable with that of Gala was also demonstrated in three lines of wheat and the five oat cultivars. Canary grass (Phalaris canariensis) was also tested and proved very susceptible to the disease. Although no specific resistance was demonstrated, the generalized resistance available offers a worthwhile means of combating crown rot.
