title: Estimation of heterozygosity in Ribes nigrum L. using RAPD markers.
abstract: Heterozygosity in three cultivars of the blackcurrant (Ribes nigrum L.) was estimated. A selfed population of each cultivar was screened for Random Amplified Polymorphic DNA markers (RAPDs) and heterozygous loci were identified by band segregation in contrast with the non-segregation of homozygous loci. On average, 21% of the loci scored in each cultivar were heterozygous. The implications for mapping studies in Ribes nigrum are discussed.
