“…In the meiosis of pollen mother cells of FI hybrids between Heines Hellkorn and Sv 01 and Sv 25, respectively, hexavalent chromosome configurations occurred most frequently. The occurrence of hexavalents in F1 hybrids of S. cereale and S. vavilovii indicates the presence of chromosomal translocations confirming earlier reports by Jain (1960), Khush & Stebbins (1961) and Carmona & Puertas (1977). In addition, seven bivalents were predominantly observed in the FI hybrid Sv 01 x Sv 25 which showed karyotypic homology between the two accessions.…”

The accurate identification and classification of wild species enhance the utilization of potential plant genetic resources_ The wild rye species Secale vavilovii Grossh. may serve to broaden the genetic variation in cultivated rye, S. cereale. The combined analyses of cytological, isozymic and other genetic characteristics in the present study revealed that of the fourteen rye accessions designated as S_ vavilovii, only three accessions were correctly classified. Thus it is essential to increase multidisciplinary, international research and collaboration to aid in the classification and utilization of the yet untapped plant germplasm.

“…This is probably due to a spontaneous extra translocation between one chromosome of the natural translocation complex and one of the rest of the genome. JAIN (1960) and KRANZ (1961) have seen a heteromorphic bivalent and another pair of chromosomes of abnormal structure carrying the nucleoli, in the hybrids of S. cereale x S. vavilovii.…”

A standard tester set of reciprocal translocations in S. cereale and several primary trisomics have been used to identify the chromosomes involved in the natural translocation complexes between S. cereale and S. montanum, and S. cereale and S. vaviloviz.Chromosomes I, III and V, in our classification system, were found to be involved in the translocations between cultivated rye, S. cereale, and both the wild species S. montanum and S. vavilovii.

“…Не-смотря на предсказанные трудности получения маркеров для ржи (Jain, 1960), сейчас уже имеется значительное количество генетических и цитологических маркеров для всех хромосом ржи. На основе сопоставления данных, полученных в результате генетического анализа ржи, пшеницы, тритикале, а также пшенично-ржаных допол-ненных и замещенных линий, было составлено подробное описание обозначений генных символов, локализации и сцепления генов ржи (Schlegel, Korzun, 2015).…”

History of rye (Secale cereale L.� breeding began from the first targeted selections made in Germany by the Probsteier Seed coo�erative around 1�50�� and over 150 years breeding yielded a tremendous amount of results. rye has also long been used as cytological subject due to its low number of chromosomes and their size. However�� genetic findings in rye u� to the early 19�0s were rather scant. About 120 genes could be assigned to seven lin�age grou�s. only through the develo�ment of new methods such as c-banding�� in situ DnA hybridization�� enzymology and molecular mar�er techniques achieved an enormous �rogress. Particularly�� the latter was driven by agronomic success of hybrid breeding in rye. The basic genetic �nowledge resulted from intra-and inters�ecies genetic diversity assay and �hylogenetic studies in the genus Secale using nuclear and cyto�lasmic molecular mar�ers facilitated successful selection of �arents for hybrid breeding and hence contributed to im�rovement of heterosis effects. Main achievements in rye hybrid breeding and genetic mechanisms ex�loited for different hybrid breeding strategies are discussed. The utilsation of landraces and wild relatives via advanced bac�cross �rocedures�� combined by QTL analysis and introgression libraries�� contributed to increase of heterotic effects. Those mar�er-assisted a��roaches became the basis of recent hybrid breeding of rye. Prediction of hybrid �erformance can also be im�roved significantly by mar�er-assisted selection and genomic selection based on genomewide mar�er data. The findings in rye genetics (including �hylogenetic�� ma��ing and �o�ulation studies� are reviewed in their relation with the hybrid breeding �ur�oses and demands. overall�� about 450 mor�hological and biochemical traits are ma��ed throughout the genome �lus about 5��000 DnA mar�ers. They are not only associated with individual chromosome or segments but also efficiently used for com�arative ma��ing (evolutionary studies�� Селекция ржи ведет сво� истори� на�иная с 1�50 г. с направленной селекции в семеновод�еском хозяйстве Probsteier (Германия�.
