Abstract
Elymus rechingeri is a tetraploid (2n = 28) cross‐fertilizer which grows in small isolated populations mainly on the Aegean islands. Chromosome morphology was studied in plants raised from seeds collected in nature and in plants resulting from inter‐ and intrapopulation crosses as well as selfing. Chromosomal polymorphism predominated in the material originating from nature and was observed both between and within populations. This polymorphism was expressed in the variable appearance of the three pairs of satellite chromosomes. The most common constitution of satellite chromosomes was found in Aegean and Egyptian materials and was considered to be the constitution characteristic of the species. Expected combinations of different types of satellite chromosomes were found in the offspring after inter‐ and intrapopulation crosses and after selfing. Some offspring plants also showed structural and numerical chromosome deviations. Fertility was lower in crosses between than within populations indicating genetical differences between populations. The karyotype of E. rechingeri shows great similarities to the karyotypes of E. furctus ssp. boreo‐atlanticus (2n = 28) and E. striatulus (2n = 14). The genome formula J1J1J3J3 was suggested for E. rechingeri. Meiosis was generally normal but asynapsis and multivalent formation at metaphase I and separation difficulties at anaphase I were also encountered.

The karyotype of E. rechingeri shows great similarities to the karyotypes of E. furctus ssp. boreo‐atlanticus (2n = 28) and E. striatulus (2n = 14). The genome formula J1J1J3J3 was suggested for E. rechingeri. Meiosis was generally normal but asynapsis and multivalent formation at metaphase I and separation difficulties at anaphase I were also encountered.</abstract><relatedItem type="host"><titleInfo><title>Hereditas</title></titleInfo><genre type="journal">journal</genre><identifier type="ISSN">0018-0661</identifier><identifier type="eISSN">1601-5223</identifier><identifier type="DOI">10.1111/(ISSN)1601-5223</identifier><identifier type="PublisherID">HRD2</identifier><part><date>1977</date><detail type="volume"><caption>vol.</caption><number>86</number></detail><detail type="issue"><caption>no.</caption><number>2</number></detail><extent unit="pages"><start>211</start><end>224</end><total>14</total></extent></part></relatedItem><identifier type="istex">082A5746468FA74312A077A8864075C58848941B</identifier><identifier type="DOI">10.1111/j.1601-5223.1977.tb01231.x</identifier><identifier type="ArticleID">HRD21231</identifier><accessCondition type="use and reproduction" contentType="copyright">© 1977 Mendelian Society of Lund</accessCondition><recordInfo><recordContentSource>WILEY</recordContentSource><recordOrigin>Blackwell Publishing Ltd</recordOrigin></recordInfo></mods><json:item><extension>json</extension><original>false</original><mimetype>application/json</mimetype><uri>https://api.istex.fr/document/082A5746468FA74312A077A8864075C58848941B/metadata/json</uri></json:item></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
