160 Forms of the Hop resistant to Mildew 



garden from to S^, and that one seedling OD 17 (?) has shown the 

 grade S^ consistently. These three seedlings may apparently be classed 

 as "commercially resistant" in the open. 



All the other seedUngs are Uable in certain seasons to be mildewed 

 to the extent of S^. 



As already mentioned, 480 seedlings have been planted out in the 

 Experimental Hop-garden. In October of each year the susceptibihty 

 of each seedling has been noted. For the greater number of these seed- 

 lings, the records have been kept for four years (1917 to 1920). An 

 analysis of these records gives us the following classification on p. 159. 



Of the 480 seedUngs, 189 (or 39-38 per cent.) proved to be males, 

 and 291 (or 60-62 per cent.) proved to be females. 



A separate analysis of the records of the two sexes gives us the 

 following classification :
