Product information is based on data from the CIMMYT South Asia 2020 Regional Trial (SAWLDT) and 2021 regional on-farm trials (ROFT 2021-1A). Actual performance will vary depending on a number of agronomic and environmental factors.
Abbreviations:
AI = artificial infestation/inoculation
BLSB = Banded leaf and sheath blight
DT = Managed drought trial
FSR = Fusarium stalk rot
GDD = growing degree-days (°C)
Opt = optimal environment
RS = random stress trial
SC = single-cross
TLB = Turcicum Leaf Blight
WL = managed waterlogging trial |
| Plant and ear aspects are scored on 1-5 scale, where 1 = desirable and 5 = undesirable characteristics |
