Two hundred and seventy cereal species and cultivars (wheat, barley, oats, rye, and Triticales), were field tested for resistance to the cereal cyst nematode (Heterodera avenae Woll.) in Victoria. Tests were made in the Wimmera District at Natimuk (1952-1954) and in the Mallee District at Walpeup (1953), and Sea Lake (1966-1969). Some species and cultivars were tested at all sites, but most were tested at one site only. All wheats tested were susceptible or very susceptible, and all Triticales were susceptible. Two barley cultivars, Morocco and Marocaine 079 were resistant, and two others were moderately resistant. The oat species, Avena sterilis and A. strigosa were resistant and fifteen cultivars of A. sativa were moderately resistant. Rye, CV. South Australian, possesses a high degree of resistance in contrast to European ryes.

Wide Range

Seven populations of the cereal cyst nematode (Heterodera avenae Woll.) from the Mallee and Wimmera districts of Victoria, were tested for their variation in pathogenicity, using a wide range of cereal species and cultivars. Avena sterilis (Cc4658), and the barleys Morocco (C13902), Marocaine 079 (C18334), and Martin 403-2 were resistant to all populations, whereas all the other cereals tested were susceptible. The three wheats, Loros (AUS11577), Psathias (AUS881), and spring wheat (AUS10894), supported fewer cysts than the susceptible standard. They may, therefore, have some potential as parents in a wheat resistance breeding program, in the absence of better sources of resistance. The results confirm the presence of only one biotype of H. avenae in Victoria, and although it is unlike any of the five European biotypes, it is similar to that from Rajasthan, India.

Avena Sterilis

Ten cereal cyst nematode (Heterodera avenae Woll.) populations from the Victorian Mallee and Wimmera districts, were tested for their variation in pathogenicity, using a selected range of indicator varieties. Of the oats used, Avena sterilis and A. strigosa were resistant to all populations, while A. abyssinica and CV. Sun II were both susceptible. None of the cultivars of barley or wheat was resistant ; the spring wheat CV. Loros was very susceptible. Rye CV. South Australian was resistant to all populations. The results presented indicate that only one biotype of H. avenae is present in Victoria, and that it is unlike any of those known to occur in Europe.

Heterodera avenae is a cereal cyst nematode that reduces wheat yields in the Pacific Northwest of the United States. Barley is also susceptible but there were no previous reports of resistance or tolerance to H. avenae in the United States. Spring barley cultivars were assayed in H. avenae-infested fields over 2 years. Cultivars were planted in plots treated or not treated with aldicarb. Forty-five cultivars were evaluated for the market classes of two- and six-row feed barley cultivars and two- and six-row malt barley cultivars. One two-row feed barley (‘Lenetah’) was ranked as resistant and four were tolerant or very tolerant. In total, 1 two-row malt barley (‘Odyssey’) was very resistant and 10 were tolerant or very tolerant. Two six-row feed and two six-row malt barley cultivars were tolerant or very tolerant but none were resistant. Seven feed barley cultivars were ranked as having a balance of at least moderate resistance plus moderate tolerance: ‘Champion’, Lenetah, ‘Xena’, ‘Idagold II’, ‘Transit’, ‘Millennium’, and ‘Goldeneye’. This is the first report of resistance and tolerance of barley in H. avenae-infested fields in the Pacific Northwest. Barley productivity can be improved by planting resistant plus tolerant cultivars or by using highly resistant and highly tolerant cultivars as parents in barley improvement programs.

Yield Responses

Significant yield responses of up to 0.9 t/ha were obtained with the nematicides aldicarb and dibromochloropropane in seven of eleven field trials with the wheat variety, Condor. Both nematicides reduced the numbers of white cysts of Heterodera avenae on the roots of wheat. With aldicarb the increase in wheat yields varied directly as the decrease in white cysts: dibromochloropropane gave similar increases in yield as aldicarb with a greater reduction in cyst numbers. There was no yield increase with either nematicide when cereal cyst nematode was not present. An analysis of covariance indicated that over all the sites 64% of the increase in yield due to aldicarb could be explained in terms of cysts of cereal cyst nematode.
