Abstract/ Executive Summary:

The experiment was carriedout at Greenhouse premises BJRI,Dhaka in 2004. There are fifty crosses were made in all possible combinations.Only twenty-five pods were developed.Among the combination JRO-524(narrow lanceolate leaf with Ped-7/95(Red stipule and stem)is our desired and within twenty-five pods only three were this combinations.

Keywords: Hybridization,Genotypes, Tossa jute

Location: Greenhouse premises BJRI,Dhaka

Start Date: 01-08-2004

End Date: 30-12-2004

Program Area: Variety and Species

Commodity: Jute

Objectives:

1.To create genetic variation to accumulate desirable genes from diverse parents into a same parent

2.To create recombinant types for accumulating desirable genes into an one offspring

Methodology:

Three cultivated varieties of tossa jute namely O-4(early maturing lanceolate leaf), O-9897(ovate lanceolate leaf),O-72()Ovate leaf), Ped-7/95(Red stipule and stem) and JRO-524(narrow lanceolate leaf) were used as parent materials and sown on August 2004.There are three same sets of parents were sown fifteen days intervals for ensuring maximum syncronization.Recommended intercultural and Agronomic were done for raising the parental materials.At afternoon, the un-opend but probably mature flowers were emasculated and bagged separately.Next morning,the emasculated flowers were pollinated by desired parent and tagging then bagging.The combination of the crosses were O-9897xO-4,O-72xO-4,.JRO-524xO-9897,JRO-524xO-72,JRO-524xO-4,O-9897xJRO-524,O-72xJRO-524,O-4xJRO-524,P-7/95xJRO-524 and JRO-524xP-7/95.Among them P-7/95xJRO-524 and JRO-524xP-7/95 combination was our more desired.
