Genetic diversity of preserved rice seed samples from the Mikawa area, Japan, stored in the Meiji era
Copyright © 2020 by JAPANESE SOCIETY OF BREEDING..
Preserved rice (Oryza sativa L.) seeds stored for nearly a century as an emergency food stocks from the Mikawa area were investigated for their genetic diversity. Morphologically, the seeds appeared to be typical Japonica. One chloroplast INDEL petN-trnC, two nuclear INDELs Acp1 and Cat1, and three SNP markers in Starch synthase IIa were amplified to characterize the molecular profile. The efficiency of amplification varied among the markers. Most of preserved seeds were classified as Japonica, but some were identified as Indica. The heterozygous genotypes detected suggested a high frequency of outcrossing at that time. On the other hand, 21 SSR markers showed quite a high degree of amplification efficiency. Principal coordinate analysis and STRUCTURE analysis based on the SSR polymorphisms proved that the preserved seeds contained alleles that were not detected among current landraces and breeding varieties, and there were the expected three subpopulations among 96 preserved seeds. These results indicated that these preserved seeds from Mikawa area in Meiji era had high genetic diversity and consisted of some subpopulations including Indica landraces with typical Japonica seed shape. These lines were considered to have been lost from current genetic resources.
