Remarks:
1/Trait evaluation.
Sub = Average % plant survival (%PS) after 15 days of flash flooding.
BLB = average lesion length in centimeters of the damage caused by the BB isolate TXO156.
Bph = Severity scores with UBN biotype at 9 DAI when TN1, the susceptible control died.
Blast = Average blast injury score when attacked by a Mixed#2 blast isolate from Thailand.
2/Agronomic characteristics.
DM (days to maturity), NTP (number of tillers per plant), PH (plant height from the soil surface to the neck of the panicle), NGP (number of grains per panicle), PSF (percent spikelet fertility), TGW (1,000 grain weight) and GY (grain yield).
3/Average values marked with different letters in the same column are significantly different at the 95% confidence level using LSD.
