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 and compare ten advanced Aus lines (F
) based on
qualitative and quantitative traits. The lines were evaluated in RCBD
with three replications. Thirty five qualitative and quantitative 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 and no. of effective tiller per plant among the lines. Maximum
no. of effective tiller was found in L10 (12.10). 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.
Five lines (L2, L3, L4, L6, and L10) were observed more effective tiller
per plant (more than 10). Two lines (L7, L9) were observed having long
panicle (26-30 cm). Highest total no. tiller per plant, no. of effective
tiller per plant, yield per plant were observed in the line L10. It was
concluded that the lines L10, L5, L3 and L4 can be selected for further
study.
