SSR studies of genetic changes in relation to long-term storage and field regeneration of rye (Secale cereale) seeds
The genetic integrity of seeds of rye cultivar Dań kowskie Złote stored in the seedbank for 25 years at 3.7 or 5.5% moisture content under vacuum or in air and regenerated in two successive seasons was assessed using 24 Simple Sequence Repeats markers. Rye seeds after storage under different conditions showed significantly different germination ability. Decrease in seed viability due to ageing resulted in increased homozygosity. Principal Coordinate Analysis showed a clear segregation of the population with the lowest seed viability in relation to the other, tested samples. Inbreeding coefficient values indicated a small variation of the seeds samples related to natural ageing.
