ABSTRACT

The experiment was conducted in 2015 at Jute Agriculture Experiment Station (JAES), Manikgonj and four regional stations (Rangpur, Faridpur, Chandina and Kishoregonj) of Bangladesh Jute Research Institute. Both qualitative (stem color, leaf color, stipule color, bud color, branching habit, leaf shape etc.) and quantitative (plant population, plant height, green weight with and without leaves, fibre wt., stick wt. etc.) types of data were recorded. In this experiment, comprising three potential breeding lines namely, BJC-5002, BJC-5050 and BJC-5105 were tested for higher yield and adaptability. Seeds were sown in randomized complete block design (RCBD) with three replications. The variety CVL-1 was used as check. The significant differences were observed among the breeding lines in respect of fibre yield, stick yield, green weight with and without leaves at Rangpur. The fibre yield (4.23 tha-1), the stick weight (9.43 tha-1), and green weight with and without leaves (73.67 and 61.78 tha-1) of BJC-5002 observed as the highest at Rangpur region. The mean performance of the breeding line BJC-5002 (3.53 tha-1), compatible with the check variety CVL-1 (3.55 tha-1) in respect of fibre yield.

 Key words: Deshi jute, breeding line, variety.
