中文摘要	genomic constitutions of three taxa of hystrix moench, h. patula, h. duthiei ssp. duthiei and h. duthiei ssp. longearistata, were examined by meiotic pairing behavior and genomic in-situ hybridization. meiotic pairing in hybrids of h. patula x pseudoroegneria spicata (st), h. patula x elymus wawawaiensis (sth), h. patula x h. duthiei ssp. longearistata, h. patula x psathyrostachys huashanica (ns(h)), h. duthiei ssp. duthiei x psa. huashanica, h. duthiei ssp. longearistata x psa. huashanica, leymus multicaulis (nsxm) x h. duthiei ssp. longearistata averaged 6.53, 12.83, 1.32, 0.29, 5.18, 5.11 and 10.47 bivalents per cell, respectively. the results indicate that h. patula has the sth genome and h. duthiei ssp. duthiei and h. duthiei ssp. longearistata have the nsxm genome. results of genomic in-situ hybridization analysis strongly supported the chromosome pairing data; therefore it is concluded that the type species of hystrix, h. patula, should be included in elymus, and that h. duthiei ssp. duthiei and h. duthiei ssp. longearistata should be transferred to leymus.
