“…We also found that the 1RS/1BL translocation had a considerable positive effect on the SSN and SL, which is consistent with the results of previous studies (Cui et al, 2012; Gao et al, 2015). QTLs were not detected for SC in any of the nine individual environments, suggesting that the 1RS/1BL translocation has no significant influence on spikelet compactness, which is inconsistent with the results of Tahmasebi et al (2015). Moreover, other studies have also shown a loose connection between the 1RS/1BL translocation and spike morphological traits (Villareal et al, 1995; Griffiths et al, 2015).…”

Wheat yield can be enhanced by modifying the spike morphology and the plant height. In this study, a population of 191 F9 recombinant inbred lines (RILs) was developed from a cross between two winter cultivars Yumai 8679 and Jing 411. A dense genetic linkage map with 10,816 markers was constructed by incorporating single nucleotide polymorphism (SNP) and simple sequence repeat (SSR) marker information. Five spike morphological traits and plant height were evaluated under nine environments for the RILs and parental lines, and the number of detected environmentally stable QTLs were 18 and three, respectively. The 1RS/1BL (rye) translocation increased both spike length and spikelet number with constant spikelet compactness. The QPht.cau-2D.1 was identical to gene Rht8, which decreased spike length without modifying spikelet number. Notably, four novel QTLs locating on chromosomes 1AS (QSc.cau-1A.1), 2DS (QSc.cau-2D.1), and 7BS (QSl.cau-7B.1 and QSl.cau-7B.2) were firstly identified in this study, which provide further insights into the genetic factors that shaped the spike morphology in wheat. Moreover, SNP markers tightly linked to previously reported QTLs will eventually facilitate future studies including their positional cloning or marker-assisted selection.

“…Отмечают адаптационную стабильность и высокий потенциал урожайности некоторых сортов мягкой пшеницы, обладающих хромосомной заменой T1BL.1RS (Hajaram et al, 1983;Villareal et al, 1997); повышенную урожайность зерна и увеличение объема выпечки у генотипов с транслокацией (Singh et al, 2009); устойчивость к стеблевой ржавчине и мучнистой росе (Friebe et al, 1989;Friebe et al, 1993). Однако исследования в условиях засухи при орошении, жары и сочетания условий стресса от жары и засухи говорят о том, что транслокация 1BL/1RS не может быть подходящим источником генетического разнообразия для повышения урожайности зерна в условиях жары и засухи (Tahmasebi et al, 2015). Хромосомная замена 1BL/1RS была включена в зародышевую плазму твердой пшеницы в CIMMYT (Mujeeb-Kazi et al,1999).…”

Replenishment of the collection of durum wheat (Triticum durum Desf.), like any other crop collection held by VIR, is a permanent process aimed at expanding the geographic, morphological and agrobiological diversity of the crop’s gene pool. A special status in this process is given to the achievements of domestic breeders, whose cultivars and lines over time remain only in the ex situ collection and constitute the national heritage of Russia. Replenishment, along with conservation, studying and sharing with the users, is a mandatory task when managing a plant germplasm collection. It can be fulfilled by sending requests for seeds to other genebanks, through the exchange with the collections of foreign research centers, contacts with individual breeders or breeding centers in Russia, or when crop cultivars are submitted to VIR from the State Register of Breeding Achievements Approved for Utilization in Russia. Besides, new accessions are added to the genebank by collecting missions.Descriptions have been made for 570 accessions included in the main catalogue of VIR’s durum wheat collection from 2000 to 2019. They originated from 28 countries of Europe, Asia, the Near East, Africa and North America, and from 16 regions of Russia.The durum wheat collection of VIR was replenished with accessions interesting both from the geographic and agrobiological viewpoints. Cultivars developed by domestic breeders are included in the global genetic resources collection primarily with the purpose of their conservation and comprehensive utilization, both now and in the future.

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.
