Linkage studies on accordion spike gene in barley

The segregation mode and linkage relationship between accordion spike and 7 marker genes come from different each linkage groups were discussed in the F₂ population of barley. In the crosses between Accordion spike barley and genetic markers, the marker genes, br, li, al, k, B and o showed the 3:1(or 1:3), but cm of Black hulles Ⅲ could not find in this study. The segregation ratio of accordion spike and normal spike genes showed 3:1, and that linkage relationship was found between the accordion spike (acr) and hooded lemma gene (K) which locused on chromosome 4 of Colsess V, even if the recombination value was very low as 38.34%. The accordion spike gene appeared to be independent from the marker genes br, li, al, B and o on the linkage analysis.
