Other claims from this paper (10)
- Intervention effect Cultivar mixtures yielded on average 7% more than their component pure stands under inoculated yellow rust conditions.
- Intervention effect Cultivar mixtures yielded on average 4% more than their component pure stands when protected from yellow rust.
- Observation Yellow rust affected all yield components of wheat, and seed weight was the component most consistently influenced.
- Association In a variance component analysis yellow rust was the most important experimental variable influencing grain yield.
- Association There was no relationship between the yield of cultivars in pure stands and their competitive abilities in mixture.
- Association Disease did not change the competitive ranking of cultivars in mixture.
- Observation Mixtures with complementary, negative and overcompensatory interactions were identified.
- Intervention effect On average, cultivar mixtures showed no greater yield stability than pure stands.
- Observation Each wheat cultivar was susceptible to one or two of the rust races used.
- Observation Component genotypes varied considerably in yield within mixtures, and the yield of the same component cultivar differed significantly between mixtures in some cases.
