Abstract/ Executive Summary:

Hybridization was done at Debigonj and Joydebpur using 46 and 82 varieties, respectively under 16 hours extended photoperiod to create variability, and for the selection of desirable genotypes. At Joydebpur, 22 out of 47 crosses and at Debigonj, 136 out of 884 crosses produced berries. In total 92.431 g hybrid seeds were produced of which 15.23 g was at Joydebpur and rest at Debigonj.

Keywords: Potato, Hybridization

Location: Joydebpur and Debigonj

Start Date: October 2011

End Date: April 2012

Program Area: Variety and Species

Commodity: Potato

Objectives:

1. Improving the genetic base of the parent population and create variants for subsequent variety selection and selection for biotic and abiotic stress tolerant and high yielding clones/varieties.

Methodology:

At Joydebpur, 46 varieties were planted on bricks followed by earthing up in non-replicated rows of 1 m length on 2nd and 27th November, 2011 and at Debigonj, 82 varieties were planted in polybag method on 25th October and 5th November 2011 in non-replicated rows of 5 m long. Day length was extended up to 16 hours with the help of HP sodium lights. Stolons and tubers those formed on bricks/polybag 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.
