For alfalfa weevil, data on percentage of resistant plants not available. 

 Ratings are based on percentage of defoliation of Team (100%). 



Data for aphid resistance expressed as percentage of seedlings surviv- 

 ing and includes plants with both high and intermediate levels of resis- 

 tance. 



For potato leafhopper, data on percentage of resistant plants not avail- 

 able. Ratings are based on percent of plant foliage yellowed and 

 correspond to visual yellowing scores of 2-3 for MSA-CW3An3 and 7-9 

 for Ranger.
