Yield Rating Key: 5 = Best; 3 = Average; 1 = Poor

Agronomic Yield Ratings are based on average performance between Alforex varieties. Actual performance may be adversely affected by extreme conditions. Unless stated, ratings are based on standardized testing procedures endorsed by the North American Alfalfa Improvement Conference.

FastGrowth Ratings are calculated by Alforex Seeds from weekly measurement of varieties grown side-by-side from green-up to harvest through the growing season. Expressed as average centimeters growth per day. >2.20 = Very Fast; >2.00 = Fast; >1.80 = Average; >1.60 = Slow; <1.60 = Very Slow

Pest Resistance Ratings

% Resistant Plants	Resistant Class	Class Abbreviation
0-5%	Susceptible	S
6-14%	Low Resistance	LR
15-30%	Moderate Resistance	MR
31-50%	Resistant	R
>50%	High Resistance	HR

IMPORTANT: Agronomic ratings based on period-of-years testing through 2018 harvest. Pest resistance, dormancy, winter survival and winterhardiness ratings based on standard test protocols prescribed and endorsed by the North American Alfalfa Improvement Conference (NAAIC) and were the latest available at the time of the publication. Ratings may change over additional years of data collection, or if NAAIC protocols change. Contact your sales professional before planting for the latest trait rating information.

DISEASE RESISTANCE INDEX: DRI is a disease index based on the following pests: Bacterial wilt, Verticillium wilt, Fusarium wilt, Anthracnose, Phytophthora, and Aphanomyces (Race 1 and Race 2). HR = 5 points, R= 4 points, MR = 3 points, LR = 2 points, S= 1 point. Highest possible DRI = 35 points.
