Abstract/ Executive Summary:

In order to create variability for selection of desirable genotypes, hybridization was done at Debiganj and Joydebpur using 38 & 40 varieties respectively under16 hours extended photoperiod. At Joydebpur, 13 varieties and at Debigonj 27 varieties/lines produced berries. In total 1078.08g hybrid seeds were produced of which 20.61 g was at Joydebpur and rest at Debigonj.

Keywords: Potato, Hybridization

Location: Joydebpur and Debigonj

Start Date: 01-09-2006

End Date: 05-07-2007

Program Area: Variety and Species

Commodity: Potato

Objectives:

1. To improve the genetic base of the parent population

2. To create variants for subsequent variety selection

3. To select disease resistant, high yielding varieties

Methodology:

At Joydebpur, forty varieties were planted on bricks followed by earthing up in non-replicated rows of 1m length on 17th November, 2006 and at Debigonj, 38 varieties/lines were planted in polybag method on Nov.10, 2006 in non-replicated rows of 5m long. Day length was extended up to 16 hours with the help of HP sodium lights. Stolons and tubers that were formed on bricks were removed time to time to accelerate flowering. Emasculation was done one day before crossing. Berries were harvested at maturity, 7 weeks after crossing. Finally seeds were extracted processed and stored for next year use.
