In the case of rye, traditional genetic analysis has been supplemented by molecular analysis resulting in more detailed genetic maps. Over this period, increased availability of inbred lines of rye has often led to a clearer genetic analysis. Molecular mapping in other members of the Triticeae has revealed a high level of synteny in the chromosomes of this group such that mapping work in one species can be related to genetic maps in other species. This has also had an impact on our knowledge of the genetics of rye. Molecular work has lead to a greater understanding of the make-up of rye chromosomes. Combined with C- banding studies (C-bands consisting of repeat sequence DNA) and studies involving in-situ hybridization, the structure of rye chromosomes has been well characterized. In the area of breeding, considerable effort has been extended to develop hybrid rye, and in many of the rye growing areas of Europe, hybrids now occupy a significant acreage. In areas related to breeding, transformation of rye has been successful, although compared to the other cereals, little work has been done in genetic engineering of rye. Anther culture for haploid production has also been reported. With this as a background, this chapter is divided into four sections: 1) genetics, 2) cytogenetics, 3) molecular genetics, and 4) breeding. |
