Selection of wild Cicer accessions for the generation of mapping populations segregating for resistance to ascochyta blight
Euphytica 130 (1), 1-9
Abstract: In order to determine genetically diverse parents for the generation of mapping populations segregating for resistance to ascochyta blight in wild Cicer species, the genetic diversity between a selection of resistant and susceptible accessions was assessed using molecular markers. Twenty Cicer accessions - comprising eight C. reticulatum accessions, six C. echinospermum accessions, five C. bijugum accessions, and one C. arietinum accession - were compared using a combination of seven RAPD primers and seven ISSR primers. A total of 231 polymorphic bands were scored and used to determine the genetic distances between accessions using Jaccard similarity coefficients. The most genetically diverse parents for the generation of intraspecific and interspecific populations segregating for resistance to ascochyta blight are reported.
