jicar stock that is as iiiiicli as possible 

 lilifflit-rcsistaut. 



Tlio variety, Pyrus iissuricnsis, along 

 with otluT varieties from China, lias 

 been experimented npon and observed 

 for several years at the Oregon Agri- 

 cnltural College, with Prof. F. C. Beimer 

 in charge of the work. With the co- 

 operation of the college, A. Ij. Wisker, 

 liead of the Loma Riea Nursery, at 

 (irass Valley, Cal., who is an extensive 

 grower of pears and a sufferer from the 

 blight, has made an exhaustive study 

 of the blight and this blight resistant 

 variety and printed a booklet outlining 

 the results of the investigation. 



Mr. Wisker states that the "full 

 value of the Oregon experiments will 

 be realized only after the passage of 

 some years, when the material assem- 

 bled by Prof. Reimer will have been 

 used by ]>lant breeders in the creation 

 of a wholly new race of hybrid pears, 

 in wliich will be combined the bliglit 

 immunity of the Asiatic species with 

 the superlative quality of our best va- 

 rieties of the European family." 



Pyrus Usurensis. 



From the restilts of the ex]ierim('iits 

 up to this time the variety P. ussuriensig 

 seems to y)e the best found. It has tlie 

 blight-resistant qualities that are so im- 

 portant, it is a good grower, it seems 

 to be resistive also to pear root aphis, 

 it has shown a tendency to have a broad 

 adaptability to varying soil types and 

 cliinati;- conditions and the experiments 

 have shown it to be wholly satisfactory 

 in nursery work. 



Tlie method of using this ])light-rc- 

 sistant variety recommended by Mr. 

 Wisker is to plant the resistant seed- 

 lings, either in orchard or nursery, to 

 head and branch the seedlings, and 

 when they are branched, to bud or graft 

 the branches to such varieties as it 

 is desired to grow. By budding or 

 grafting commercial varieties upon the 

 branches, the vital parts of the tree, the 

 root, trunk and main-limb crotches, all 

 consist of the blight-resistant seedling. 

 If the blight should destroy all or part 

 of the upper portion of the tree, it may 

 be readily renewed by top-working upon

Other Varieties. 



There are several Chinese species 

 other than P. ussuriensis that exhibited 

 great resistance to blight during the 

 exjieriments. One that shows great 

 promise is P. Calleryana, which grows 

 in the lowland swamps in China and 

 seems to have tolerance for abundant 

 moisture even greater than 1'. ussuri- 

 ensis. 



Mr. Wisker also states tliat, before 

 nurserymen can regularly supply or-

must be established in the United 

 States, where climatic conditions will 

 not interfere with seed crops. This is 

 because the variety blooms early and, 

 in northern China wliere the tree grows, 

 late frosts are frecpient and, conse- 

 ((uently, the seeds are diflticult to obtain. 

 And then, too, the ignorance and unre- 

 liability of the native seed collectors 

 in sections where other varieties of 

 pyrus abound is a factor to be reckoned 

 with. 



"Control by putting a blight-proof 

 foundation under every pear tree is the 

 best that can be expected until plant 

 breeders produce an entirely new race 

 of pears," is the statement made.
