Устойчивост на чуждестранни сортове и линии Грах (Pisum Sativum L.) към Pseudomonas Syringae PV. Pisi
Resistance of foreign pea cultivars and lines (Pisum Sativum L.) to Pseudomonas

Summary/Abstract: The investigation was carried out during 2013-2014 at Dobrudzha Agricultural Institute, General Toshevo. Thirty six foreign pea cultivars and lines with different morphological traits were used. Two strains of P.s. pv. pisi (Bz4 and NCPPB 2585) were used for inoculation. The accessions were inoculated twice: at phenophase budding (petioles) and at grain filling (pod). One accession had immune and 20 accessions had resistant/middle resistant reaction of leaves and pods to strain NCPPB. Fourteen accessions had immune/resistant/middle resistant phenotype of leaves and pods to strain Bz4. Nine accessions had immune/resistant/middle resistant phenotype of leaves and pods to both strains of P.s.pv. pisi. These accession can be used as a donor parent in a disease resistance breeding program.
