Germplasm and molecular markers for Disease Resistance in Potato

摘要

Refers to a New Germplasm, Stock breeding, genetic markers and Methods for introducing resistance to anublo disease caused by the fungus Phytophthora infestans.And other diseases of Cultivated Potato. The Germplasm derived from a segment of the Genome of Solanum bulbocastanum is introduced into the Cultivated Potato by somatic hybridization.Bulbocastanum with S. Tuberosum. Also provided is a marker of APAA Fragment of S.Bulbocastanum that cosegrega Gene with resistance to Disease; PLFR markers of Chromosome 8, which are also closely linked to the resistance genes,These Markers are used to monitor the passage of Disease Resistance trait in Crosses of cultivation.The markers are also used to facilitate the isolation of the Gene or genes of S. bulbocastanum responsible for Disease Resistance
