Abstract/ Executive Summary:

In order to create variability for selection of desirable genotypes, hybridization was done at Debigonj and Joydebpur using 40 and 72 varieties respectively under 16 hours extended photoperiod... At Joydebpur, 15 varieties and at Debigonj 40 varieties produced berries. In total 568.12 g hybrid seeds were produced of which 53.62 g was at Joydebpur and rest at Debigonj.

Keywords: Hybridization, Potato

Location: Joydebpur and Debigonj

Start Date: 01-08-2007

End Date: 05-07-2009

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, seventy two varieties were planted on bricks followed by earthing up in non-replicated rows of 1m length on 22 nd November, 2007 and at Debigonj, 40 varieties were planted in polybag method on Nov.16, 2007 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.
