Abstract/ Executive Summary:

Two sets of experiment were conducted under this experiment A) Seven F₅ lines derived from different cross combinations among the indigenous and exotic accessions were raised at BJRI, Head Quarter adjacent field. The parents were also sown in 3m long rows with single line. Among the F5 lines, thirty-five plants were selected based on their higher plant height, cylindrical shape, fast growth and tolerance to diseases. B) F₂generation of eight cross combinations viz. Acc. 1833 x cap. Dwarf type (red) x Acc. 1515, cap Dwarf type (red) x BINA vegetable, BINA vegetable x Acc. 1515, BINA vegetable x cap Dwarf type (red), Acc. 1833 x BINA vegetable, BJC-718 x Lalshachi and BJC-718 x trilocularis were raised in the BJRI adjacent field. Twenty-five plants were selected based on their dwarfness, bushy, tase of leaves and tolerance to diseases. In addition to these, F₃ generation of cross combination of cap dwarf type (red) x BINA vegetable was studied and desirable ten bushy plant types were selected.

Keywords: Desirable lines, High yield and white jute.

Location: BJRI Head Office, Dhaka

Start Date: 18-04-2010

End Date: 31-03-2010

Program Area: Variety and Species

Commodity: Jute

Objectives:

A. To develop breeding lines which is a) photo and thermo insensitive especially allowing more flexible of sowing and harvesting time with optimum biomass formation, (b) tolerance to problem soil, (c) superior quality of fibre producing characteristics for diversified and their uses. B. To develop breeding lines of dwarf capsularis having more delicious leaves.

Methodology:

Two sets of experiment were conducted under this experiment:- A) Seven F₅ lines derived from different cross combinations among the indigenous and exotic accessions were raised at BJRI, Head Quarter adjacent field. The parents were also sown in 3m long rows with single line. Standard agronomic practices were followed for proper growth of the materials. Among the F₅lines, thirty-five plants were selected based on their higher plant height, cylindrical shape, fast growth and tolerance to diseases. B) F₂ generation of eight cross combinations viz. Acc. 1833 x cap. Dwarf type (red) x Acc. 1515, cap Dwarf type (red) x BINA vegetable, BINA vegetable x Acc. 1515, BINA vegetable x cap Dwarf type (red), Acc. 1833 x BINA vegetable, BJC-718 x Lalshachi and BJC-718 x trilocularis were raised in the BJRI adjacent field. Twenty-five plants were selected based on their dwarfness, bushy, tase of leaves and tolerance to diseases. In addition to these, F₃ generation of cross combination of cap dwarf type (red) x BINA vegetable was studied and desirable ten bushy plant types were selected.
