1910.] Potatoes Resistant to Wart Disease. 557 



and Sutton's Abundance showed a certain amount of disease, 

 and Findlay's Conquest was badly attacked. The results at 

 this centre showed that some varieties which usually resist the 

 disease successfully may be attacked if the land is thoroughly 

 impregnated with spores of the disease. At the other centres 

 results in conformity with those of 1909 were obtained. 

 Findlay's Conquest, Golden Wonder, and Langworthy were 

 planted at four places; Snowdrop and Sutton's Abundance at 

 three places ; and What's Wanted at one, and in all cases they 

 showed no trace of Wart Disease. Other varieties that were 

 grown at from one to four places and were not attacked 

 were: — Early Varieties: — Aberlady Early, Southern Queen, 

 Southern Star; Second Earlies : Favourite, St. Malo Kidney, 

 Supreme; Maincrop : Champion, Chiswick Favourite, 

 Crofter, Laird, Prolific, Provost, Reading Giant, Rector, 

 Schoolmaster, White City, Peacemaker. Millcross Early was 

 free from disease at two centres. Snowdrop was this year 

 planted at three centres, at two of them on duplicate plots, 

 and was not affected, although at Holmes Chapel, where but 

 few varieties escaped, it was attacked. 



In addition to these experiments trials were made under 

 various conditions on allotments. The Board distributed, in 

 the spring of 1910, "seed" potatoes of the varieties known 

 as Conquest, Langworthy, and Golden Wonder among 

 allotment holders in several selected districts of Lancashire, 

 Cheshire, Nottinghamshire, Leicestershire, Staffordshire, 

 Shropshire, &c. 



The results which have been reported to the Board up to 

 the present have been satisfactory, the potatoes that have 

 been lifted showing very little disease in any case, and 

 none at all in most, while non-resistant varieties, such as 

 Up-to-Date, planted in the same garden, were frequently a 

 mass of wart and quite useless. Reports as to the cropping 

 quality of the potatoes varied. From Alfreton, Langworthy 

 and Golden Wonder were reported as cropping badly, while 

 Conquest was a very good crop. At Burton-on-Trent all 

 three varieties, though free from disease, were considered un- 

 suitable to the soil. Excellent reports both as to yield and 

 quality were received from Sutton Coldfield. At Huyton 

 Quarry Golden Wonders were said to be small. At Chebsey
