title: Mapping of sequence-specific markers and loci controlling preharvest sprouting and alpha-amylase activity in rye (Secale cereale L.) on the genetic map of an F2 (S120&times;S76) population.
abstract: Location of the loci that control preharvest sprouting and alpha-amylase activity in rye was studied based on intercross S120&times;S76, consisting of 110 genotypes of F2 and F3 progenies. The genetic map currently consists of 141 loci distributed in 11 linkage groups, covering a distance of 506.4 cM, and was enriched during this study with 24 sequence-specific markers (7 SCARs, 7 SSRs, and 10 STSs). The extended map was applied for composite interval mapping of the loci controlling preharvest sprouting and &alpha;-amylase activity, revealing 3 significant QTLs for preharvest sprouting, located on chromosomes 3R, 5R and 6R (in 1999), and one QTL for &alpha;-amylase activity found on chromosome 2R (in 2000).
