Assessment of genetic diversity of accessions in Brassicaceae genetic resources by frequency distribution analysis of S haplotypes
Abstract Plant genetic resources are important sources of genetic variation for improving crop varieties as breeding materials. Conservation of such resources of allogamous species requires maintenance of the genetic diversity within each accession to avoid inbreeding depression and loss of rare all...

| 520 | |a Abstract Plant genetic resources are important sources of genetic variation for improving crop varieties as breeding materials. Conservation of such resources of allogamous species requires maintenance of the genetic diversity within each accession to avoid inbreeding depression and loss of rare alleles. For assessment of genetic diversity in the self-incompatibility locus (S locus), which is critically involved in the chance of mating, we developed a dot-blot genotyping method for self-incompatibility (S) haplotypes and applied it to indigenous, miscellaneous landraces of Brassica rapa, provided by the IPK Gene Bank (Gatersleben, Germany) and the Tohoku University Brassica Seed Bank (Sendai, Japan), in which landraces are maintained using different population sizes. This method effectively determined S genotypes of more than 500 individuals from the focal landraces. Although our results suggest that these landraces might possess sufficient numbers of S haplotypes, the strong reduction of frequencies of recessive S haplotypes occurred, probably owing to genetic drift. Based on these results, we herein discuss an appropriate way to conserve genetic diversity of allogamous plant resources in a gene bank. | ||

Conservation of such resources of allogamous species requires maintenance of the genetic diversity within each accession to avoid inbreeding depression and loss of rare alleles. For assessment of genetic diversity in the self-incompatibility locus (S locus), which is critically involved in the chance of mating, we developed a dot-blot genotyping method for self-incompatibility (S) haplotypes and applied it to indigenous, miscellaneous landraces of Brassica rapa, provided by the IPK Gene Bank (Gatersleben, Germany) and the Tohoku University Brassica Seed Bank (Sendai, Japan), in which landraces are maintained using different population sizes. This method effectively determined S genotypes of more than 500 individuals from the focal landraces. Although our results suggest that these landraces might possess sufficient numbers of S haplotypes, the strong reduction of frequencies of recessive S haplotypes occurred, probably owing to genetic drift. Based on these results, we herein discuss an appropriate way to conserve genetic diversity of allogamous plant resources in a gene bank.

Conservation of such resources of allogamous species requires maintenance of the genetic diversity within each accession to avoid inbreeding depression and loss of rare alleles. For assessment of genetic diversity in the self-incompatibility locus (S locus), which is critically involved in the chance of mating, we developed a dot-blot genotyping method for self-incompatibility (S) haplotypes and applied it to indigenous, miscellaneous landraces of Brassica rapa, provided by the IPK Gene Bank (Gatersleben, Germany) and the Tohoku University Brassica Seed Bank (Sendai, Japan), in which landraces are maintained using different population sizes. This method effectively determined S genotypes of more than 500 individuals from the focal landraces. Although our results suggest that these landraces might possess sufficient numbers of S haplotypes, the strong reduction of frequencies of recessive S haplotypes occurred, probably owing to genetic drift. Based on these results, we herein discuss an appropriate way to conserve genetic diversity of allogamous plant resources in a gene bank.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Genetic Drift</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Dominance Relationship</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Neutral Locus</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Brassicaceae Species</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Allogamous Species</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Oikawa, E.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Kitashiba, H.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Nishio, T.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Theoretical and applied genetics</subfield><subfield code="d">Berlin : Springer, 1929</subfield><subfield code="g">120(2009), 6 vom: 29.

Assessment of genetic diversity of accessions in Brassicaceae genetic resources by frequency distribution analysis of S haplotypes |
| abstract |
Abstract Plant genetic resources are important sources of genetic variation for improving crop varieties as breeding materials. Conservation of such resources of allogamous species requires maintenance of the genetic diversity within each accession to avoid inbreeding depression and loss of rare alleles. For assessment of genetic diversity in the self-incompatibility locus (S locus), which is critically involved in the chance of mating, we developed a dot-blot genotyping method for self-incompatibility (S) haplotypes and applied it to indigenous, miscellaneous landraces of Brassica rapa, provided by the IPK Gene Bank (Gatersleben, Germany) and the Tohoku University Brassica Seed Bank (Sendai, Japan), in which landraces are maintained using different population sizes. This method effectively determined S genotypes of more than 500 individuals from the focal landraces. Although our results suggest that these landraces might possess sufficient numbers of S haplotypes, the strong reduction of frequencies of recessive S haplotypes occurred, probably owing to genetic drift. Based on these results, we herein discuss an appropriate way to conserve genetic diversity of allogamous plant resources in a gene bank. © Springer-Verlag 2009 |
