Stuart, Wm., Disease-resistant potatoes. (Bulletin Ver- 

 mont Agricl. Expt. Station. CXV. p. 135—140. 1905.) 



The disease of potatoes caused by Pliytoplithora infestans has led 

 to a widespread interest in the methods of constating tiiis disease, and 

 the newer development in this direction has resulted in the breeding of 

 varieties immune to the fungus. The work of the writer began about 

 two years ago and has resulted in the following Statement of conclusions : 

 Some varieties are less subject to vine injury than öthers. Some show 

 a greater tuber resistance to rot than others. With some there seems 

 to be a fairly close relation between resistance of vine to disease and 

 the tuber to rot. Selection has not given visible increase of resistance. 

 Hybridization and the growing of seedling plants foUowed by careful 

 selection seems to ofier a more logical method of securing disease-resistant 

 varieties than does selection. Perley Spaulding.
