^a/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 including TXO152, TXO85, TXO155 and TXO156
BPH = Severity scores with UBN biotype at 9 DAI when TN1, the susceptible control died
Blast = Average blast injury score when attacked by 8 mixed blast isolates from Thailand
^b/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), PSF (percent spikelet fertility), TGW (1000-grain weight) and GY (grain yield)
^c/Grain quality and cooking quality
BR (brown rice), HR (head rice), GL/W (grain length-width ratio), PRL (polished rice length), AC (amylose content; Julaino, 1971), ASV (alkaline spreading value)
EDV = Essentially-derived variety
