Among the cereals, rye (Secale cereale L.) can be grown under extreme climatic and poor soil conditions and, is a major crop in North Europe. In the present paper, we report the development of a genetic linkage map of rye using a pooled F2 mapping population created from a reciprocal cross of two self-fertile inbred lines. The 183 mapped markers consist 139(More)
Using the marker information of 275 F2 plants quantitative traits determining morphological and yield characters were studied analyzing F3progenies grown in four different experiments at three sites. The map constructed contains 113 markers including the major dwarfing gene Ddw1 with an average distance of about 10 cM between adjacent markers. Of the 21(More)
 Three mutations determining self-fertility at the S, Z and S5 self-incompatibility loci on chromosomes 1R, 2R and 5R of rye, respectively, were mapped using three different F2 populations. There was a close linkage of one isozyme and four RFLP markers, and no recombinant plants were detected. These markers are Prx7, Xiag249 and Xpsr634 for the S locus(More)
The segregation of several isozyme marker genes has been studied in F2 inbred families from hybrids between self-sterile and five self-fertile inbred lines (nos. 2, 3, 4, 5, and 8) as well as from interline hybrids. Self-pollination of F1 hybrids between self-sterile forms and lines 5 and 8 gave an F2 segregation ratio of 1 heterozygote:1 homozygote for the(More)
The wheat and rye spike normally bears one spikelet per rachis node, and the appearance of supernumerary spikelets is rare. The loci responsible for the ‘multirow spike’ or MRS trait in wheat, and the ‘monstrosum spike’ trait in rye were mapped by genotyping F2 populations with microsatellite markers. Both MRS and the ‘monstrosum’ trait are under the(More)
 Three mutant loci of rye determining absence of ligules (al), waxless plant (wa1) and waxy endosperm (Wx) characters were mapped in a single F2 population, comprising 84 individual plants. The three loci could be clearly tagged in relation to 7 (al on chromosome 2R), 4 (wa1 on chromosome 7R) or 6 (Wx on chromosome 4R) RFLP markers. The mapping data are(More)
The phenotypic manifestation and genetic control of embryo lethality observed in crosses between common wheat and rye were studied. It was found that crosses between common wheat and inbred self-fertile rye lines L2 and 535 gave rise to ungerminating grains, in which the development and differentiation of the hybrid embryo are arrested. Study of the degree(More)
Eight mutant loci determining the traits waxy plant (w and wa1), brown culm (cb), multiple pistils (mp), weak plant with reduced plant height (np), monoculm growth habit (mc), compactum growth habit (ct3) and anthocyaninless (an) were mapped on rye chromosomes 4R (w, np), 6R (cb, mc) and 7R (mp, wa1, ct3, an). For five mutants (w, wa1, cb, mp, np) molecular(More)
In F2 hybrids between self-sterile plants of the Volkhova cultivar and self-fertile lines with established self-fertility mutations (sf mutations) at the major incompatibility loci S (1R), Z (2R), and T (5R), the effect of sf mutations on the inheritance of secalin-encoding, isozyme, and morphological markers located on the same chromosomes was(More)
Crosses between hexaploid wheat and rye can only succeed when pre- and post-zygotic barriers have been overcome. A rye gene determining embryo lethality (Eml-R1), which is involved in post-zygotic isolation, has been mapped to chromosome 6R. In the present paper the mode of inheritance of Eml-R1 was studied by employing a wheat/rye chromosome 6R addition(More)
