Abstract: In order to blend the quality characters with high yield, IR 30 was crossed with Basmati 370 and pedigree breeding method was followed up to F10th generation and 18 stable recombinant inbred lines (RILs) were developed. They were evaluated along with two local popular high yielding varieties i.e., Satabdi (IET 4786) and Khitish (IET 4094) as check during kharif 2009 and boro 2009-2010. Five lines showed ≥ grain yield in comparison of standard checks. All the RILs showed early maturity (112-120 days) similar to the checks. Four lines possess strong pleasant aroma and among them two lines had grain yield equivalent to that of the checks. Nine lines possess extra-long slender grain (>7.5 mm grain length and >3.0 L/B ratio).
