Analysis of PDR1 retrotransposon insertions in the pea (Pisum Sativum L.)

We research polymorphism of PDR1 insertion grades, lines, and mutants of peas by means of seven pairs of specific RBIP-primers. Seven PDR1 insertions loci are identified in the studied forms of peas. We establish the high level of polymorphism of PDR1 retrotransposon inserts with primers RBIP2, RBIP1794, and RBIP64, that has made 92, 82.98 and 78%, respectively. The genetic analysis in a population of F2 hybrids (Chil 15 × WL1238) is conducted. RBIP700 polymorphic fragment is localized on a genetic map of peas in the third group of coupling.
