Abstract/ Executive Summary:

The experiment was performed at Greenhouse premises at BJRI,Dhaka in 2012 following RCBD methods. There are several crosses (80) were made in all possible combinations.only few (15) successful pods were obtained from the crosses.Weather was not favorable for successful pod formation, so the rate of success is low. C. incisifolius leaf is a serrated type parent and were used with other high yielding varieties but having no F₁ seeds. The success of cross depends on compatibility of the parents.JRO-524 is a more compatible parents .

Keywords: Hybridization, Synchronization, Pollination. Genetic variability

Location: Greenhouse premises, BJRI, Dhaka

Start Date: 01-09-2012

End Date: 30-12-2012

Program Area: Variety and Species

Commodity: Jute

Objectives:

To create genetic variability, To combine different characters into a diverse parent

Methodology:

Twenty genotypes including four cultivated varieties of tossa jute namely O-4, O-9897,BJRI Tossa pat-4, BJRI Tossa pat-5 and O-3820,JRO-524,Acc-632,Acc-1033,Acc-1043,Acc-1051,Acc-1056 and C.Incisifolius were used as parent materials and sown on September 2012.There are three same sets of parents were sown fifteen days intervals for ensuring maximum synchronization.Recommended intercultural and Agronomic were done for raising the parental materials.At afternoon, the un-opened but probably mature flowers were emasculated(removal of male part/stamen) and bagged separately.Next morning,the emasculated flowers were pollinated by desired parent and tagging then bagging.The developed hybrids pods were maintained as F₁and next year conformation test.
