All ratings are general. Different pathotypes, races, and biotypes of diseases and insects can cause ratings to change.
All ratings are based on Warner field screenings and university screenings.
HR = High Resistance, HT = Highly Tolerant, T = Tolerant, MT = Moderately Tolerant, S = Susceptible, 1 = Poor, 10 = Excellent
Management Notes:
W-644-E is an excellent medium maturity hybrid with great height uniformity. It has high greenbug resistance to biotypes
C and E. Ease of harvest and adaptation to limited irrigation or areas of moderate annual rainfall make W-644-E a strong
choice for red grain sorghum production. |
