Mutants and duplication in chromosome 7 (syn. 5H) in the barley line HA21: duplications may enhance QTLs and serve to make constant linear cis-heterozygosity.

Abstract excerpt

Cytological and linkage data indicate a duplication in the short arm of chromosome 7 (syn. 5H) in the mutant line HA21 (barley, Hordeum vulgare, cv. 'Pirkka'). The associated mutant (ha21) shows a weighted average linkage of 22.1 cM with pld, hitherto an ignored anthocyaninless gene, of cv. Pirkka. Some crosses produce F2 segregants with an exaggerated ha21 phenotype which may represent position effect or...
