Abstract
The present study was conducted at the experimental farm, Department of Genetics and Plant Breeding, Sher-e-Bangla Agricultural University, Dhaka during Aus season, 2017. The experiment was carried out to characterize ten advanced Aus lines (F8) based on qualitative traits. The lines were evaluated in RCBD with three replications. Thirty one qualitative traits were used to characterize the advanced lines. Variation was observed in the traits like leaf pubescence, shape of the ligule, attitude of the blade of flag leaf, days to heading, days to maturity, 1000-grain weight, grain length (without dehulling), sterile lemma length, decorticated grain length (after dehulling), decorticated grain shape, culm length, panicle length. Minimum days to heading was found in L1, L2, L3, L4, L5, and L10. Early maturity was found in L1, L2, L3, L4, L5, and L10. 1000 grain wt. was highest in L2, L4, L6, L7, and L8. Six lines (L1, L2, L3, L4, L5, and L10) showed early time of heading, early maturing and medium type of culm length. Two lines (L7, L9) were observed having long panicle (26-30 cm). It was concluded that the lines L10, L5, L3 and L4 can be selected for further study.
