Keywords: ConfirmationF1,Hybrids vigor, Tossa Jute

Location: Greenhouse,Dhaka

Start Date: 01-03-2006

End Date:

Program Area: Variety and Species

Commodity: Jute

Objectives:

1.To search the desired character recurs or not to F1

2.To confirm the target character recurs or not to F1

Methodology:

Forty(40) crosses were made in 2005 but twenty-five(25) produced pods,among these, eleven(11)pods produced seed successfully.The produced eleven was F1.The combination ware 1.O-4xO-9897,2.O-4xO-9897,3.O-9897xBJRI tossa pat-4(O-72),4.JRO-524xBJRI tossa pat-4(O-72),5.JRO-524xSDLT-1,6.JRO-524xSDLT-1, 7.F1xBINA,8.F1xBINA,9.

The seeds were sown in earthen pot.Proper intercultural operation and agronomic practices were maintained.Diseases infected and pest infested plants were removed from the pot.Top cutting were performed after 100 days of sowing in the stations must keeping isolation distance preferably in pots in Central station ,Dhaka.The parental line like plants may appears or not.Generally hybrids showed vigor in nature.If produced plants is desired was selected for next year.
