Alfalfa Disease Resistance Ratings
This publication provides disease ratings for registered varieties of alfalfa.
Resistance to diseases can be an important consideration in the selection of an
appropriate variety, but there are many other agronomic factors to consider as well. Not
all of the varieties listed will be suitable for every region of British Columbia. Contact
your local BCMAFF office for recommended varieties for your area.
Legend: HR = highly resistant; R = resistant; MR = moderately resistant; S =
susceptible
