Allelic share among two taxonomically related Elymus species,hexaploid E . nutans Griseb and tetraploid E . burchan‐buddae (Nevski) Tzvelev

摘要：

Two taxonomically related Elymus species, E.nutans Griseb and E.burchan‐buddae ( Nevski) Tzvelev, are among the most abundant perennial grasses and widely distributed across the north western China.The two Elymus species are very similar in their morphology, although the important character that distinguishes them with certainty is chromosome number and genomic constitution (L ve,1984) as E.nutans is hexaploid (2n＝ 6x ＝ 42, StStYYHH) and E.burchan‐buddae tetraploid (2 n＝ 4 x ＝ 28,StStYY).Effects of different ploidy genome on the plant genetics have been paid more attention.This study is to test the consanguinity between two Elymus species with different ploidy through shared AFLP (amplified fragment length polymorphisms) allelic frequencies, and induce the causal genome of.
