AB  - A set of 100 IRRI bred advanced breeding lines were tested at Gazipur 
(as moderate productive control site) and at Habiganj (as high 
productive site) following row-column design with 2 replications. The 
breeding lines were highly variable in days to maturity and plant height
 but not in grain yield. However the interaction effects between 
genotype and environment (GXE) were significant for all three traits. At
 Gazipur, the breeding lines yielded with range between 3.3 to 7.3 t/ha 
with a growth duration range of 138-154 days, while at Habiganj they 
yielded 5.1-7.9 t/ha with growth duration of 139-159 days. The highest 
yielding genotype was IR99092-B-B-78 followed by IR13A390, 
IR99061-B-B-7, IR14D111, etc at Gazipur, while IR13A390 followed by 
IR100008-91-B yielded the highest at Habiganj site. Based on yield and 
growth duration, 22 breeding lines showing better performance at 
Gazipur, 9 lines at Habiganj and 2 lines for both locations were 
selected for further evaluation.
