Other claims from this paper (19)
- Intervention effect Crops from clean and moderately infected seed did not differ detectably in growth or yield.
- Intervention effect Plants from severely infected seed tubers emerged more slowly and had fewer stems.
- Intervention effect Severely infected seed reduced the yield of King Edward potatoes by 20 %.
- Intervention effect Severely infected seed reduced the yield of Majestic potatoes by 13 %.
- Intervention effect Severely infected King Edward seed yielded almost 4 tons/acre less of 1 1/4-2 1/4 inch tubers.
- Intervention effect Severely infected Majestic seed yielded 1 ton/acre less of 1 1/4-2 1/4 inch tubers.
- Intervention effect Severely infected Majestic seed yielded 2 tons/acre less of 2 1/4-3 1/4 inch tubers.
- Intervention effect The total yield from King Edward seed stocks with skin spot was only slightly less than from clean tubers.
- Intervention effect The total yield from Majestic seed stocks with skin spot was only slightly less than from clean tubers.
- Intervention effect Seed severely infected by Oospora pustulans often increased infection of the progeny tubers.
- Intervention effect Seed severely infected by Oospora pustulans usually decreased progeny infection by Rhizoctonia solani and sometimes by Helmintho-sporium solani.
- Observation Seed with one, two, three and more live eyes yielded equally.
- Observation About half of the tubers without live eyes eventually produced plants.
- Observation Plants from tubers without live eyes were late and had few stems.
- Intervention effect Tubers without live eyes gave only half the yield of seed with three or more live eyes.
- Observation Progenies of King Edward and Majestic seed grown on seven farms were more infected in 1963 than in 1964.
- Observation Infection of progenies differed widely between farms in each year.
- Association Where Oospora pustulans was common, Rhizoctonia solani was often scarce, and vice versa.
- Observation Progenies of King Edward stocks very differently infected by Oospora pustulans were almost uniformly infected at Rothamsted.
