Abstract: The difference between hybrid and inbred rice was studied in respect of their growth duration, yield and quality in Boro season, 1999. Among the varieties, Aalok 6201 had the highest grain yield followed by BRRI Dhan29 and IR68877H but statistically they were similar. BRRI Dhan28 had the lowest grain yield, which was statistically similar to Loknath503. BRRI Dhan28 and the tested hybrid rice had lower growth duration than BRRI Dhan29. Milling out turn varied from 67 to 70% among the tested varieties. Loknath 503 had the lowest milling out turn (70%) and, BRRI Dhan28 and BRRI Dhan29 had the highest milling out turn (70%) for unparboiled but parboiled rice the highest milling out turn(73%) were found in BRRI Dhan28 and IR68877H . All tested hybrid rice were medium bold, whereas BRRI Dhan29 and BRRI Dhan28 were medium slender and long slender, respectively in both parboiled and unparboiled condition. Among the varieties, amylose content (%) was higher in BRRI Dhan29 and protein content (%) was higher in IR68877H for both under parboiled and unparboiled condition. Alkali spreading value was higher in BRRI Dhan28. Cooking quality of all the varieties was more or less similar.
