Homoeologous group 5 chromosomes of wheat possess genes that have a significant influence on the time of earing, growth habit (Vrn), frost resistance (Fr) and winter hardiness. The Vrn-A1/Fr-A1, Vrn-B1/Fr-B1 and Vrn-D1/Fr-D1 genes are assigned to the long arm of the 5A, 5B and 5D chromosomes, respectively. In rye (Secale cereale L.), Vrn-R1/Fr-R1 genes, which determine the growth habit and cold/frost resistance, are localized on chromosome 5RL. To investigate the effect of individual chromosomes on winter hardiness, as well as their interactions with the background, wheat-rye 5R(5A)-substituted lines based on winter and spring wheats were used in this study. We created the wheat-rye 5R(5A) substitution lines based on the winter wheats cvs. ‘Filatovka’ and ‘Ulʼynovka’ and based on the spring wheats cvs. ‘Rang’ and ‘Mironovskaya krupnozernaya’ to identify the role of rye chromosome 5R in controlling the growth habit and winter hardiness. Two cultivars of rye—‘Onokhoiskaya’ (spring habit) and ‘Vietnamskaya Mestnaya’—are the source of chromosome 5R. We do not know the growth habit of rye ‘Vietnamskaya Mestnaya’. Field experiments were carried out over three years during the winters of 2015/2016, 2016/2017 and 2017/2018 in the Novosibirsk Region. It was found that 5R(5A) substitution lines for spring cvs. ‘Rang’ and ‘Mironovskaya krupnozernaya’, with the participation of the spring rye ‘Onokhoiskaya’, have a winter habit. The wheat-rye 5R(5A) lines for winter cvs. ‘Ul'yanovka’ and ‘Filatovka’, with the participation of rye ‘Vietnamskaya Mestnaya’, have a facultative habit. These substituted lines can grow in both spring and autumn sowing. The evaluation of winter hardiness conducted was carried out by means of visual scoring on a 1–9 score basis. All wheat-rye-substituted lines survived in the conditions of the Novosibirsk Region. Winter hardiness scores ranged from 5 to 6 after the 2015/2016 and 2016/2017 winters, whereas winter hardiness scores varied from 8 to 9 after the 2017/2018 winter.

小麦的同源5族染色体具有对发穗时间，生长习性（Vrn），抗冻性（Fr）和耐寒性具有显着影响的基因。所述Vrn的-A1 / FR-A1，Vrn的-B1 / FR-B1和Vrn的-D1 / FR-D1基因被分别分配给图5A的长臂，5B和5D染色体，。黑麦（Secale graine L。），Vrn-R1 / Fr-R1决定生长习性和抗寒/抗霜冻性的基因位于5RL号染色体上。为了研究单个染色体对耐寒性的影响及其与背景的相互作用，本研究使用了基于冬小麦和春小麦的小麦-黑麦5R（5A）-取代品系。我们基于冬小麦CVS创建了小麦-黑麦5R（5A）替代系。'Filatovka'和'Ulʼynovka'，并基于春季小麦CVS。'Rang'和'Mironovskaya krupnozernaya'确定黑麦5R染色体在控制生长习性和抗寒性中的作用。黑麦的两个品种-'Onokhoiskaya'（春季习性）和'Vietnamskaya Mestnaya'-是5R号染色体的来源。我们不知道黑麦'Vietnamskaya Mestnaya'的生长习性。在2015/2016年，2016/2017年和2017/2018年冬季的三年中，在新西伯利亚地区进行了三年的现场试验。发现弹簧cvs的5R（5A）替代品系。春季黑麦“ Onokhoiskaya”的参与下，“ Rang”和“ Mironovskaya krupnozernaya”有冬季习性。用于冬季cvs的小麦黑麦5R（5A）品系。黑麦“ Vietnamskaya Mestnaya”的参与下，“ Ul'yanovka”和“ Filatovka”有一种兼性的习惯。这些替代品系可以在春季和秋季播种时生长。通过视觉评分以1–9评分为基础对冬季耐寒性进行评估。所有小麦黑麦取代品系均在新西伯利亚州的条件下存活。在2015/2016年和2016/2017年冬季之后，耐寒性评分从5到6不等，
