“…However, the released G-type hybrid cultivars demonstrate the general feasibility of hybrid breeding using alternative hybridization systems in rye. The genetic diversity between the mitochondrial genomes of G- and P-type CMS hybrids [ 51 , 59 , 61 , 62 , 63 ] serves to reduce the potential genetic vulnerability of highly productive rye hybrids and asks for intensified research to unravel the genetic basis of the cyto-nuclear interaction of G-type CMS.…”

Rye is the only cross-pollinating small-grain cereal. The unique reproduction biology results in an exceptional complexity concerning genetic improvement of rye by breeding. Rye is a close relative of wheat and has a strong adaptation potential that refers to its mating system, making this overlooked cereal readily adjustable to a changing environment. Rye breeding addresses the emerging challenges of food security associated with climate change. The systematic identification, management, and use of its valuable natural diversity became a feasible option in outbreeding rye only following the establishment of hybrid breeding late in the 20th century. In this article, we review the most recent technological advances to improve yield and yield stability in winter rye. Based on recently released reference genome sequences, SMART breeding approaches are described to counterbalance undesired linkage drag effects of major restorer genes on grain yield. We present the development of gibberellin-sensitive semidwarf hybrids as a novel plant breeding innovation based on an approach that is different from current methods of increasing productivity in rye and wheat. Breeding of new rye cultivars with improved performance and resilience is indispensable for a renaissance of this healthy minor cereal as a homogeneous commodity with cultural relevance in Europe that allows for comparatively smooth but substantial complementation of wheat with rye-based diets, supporting the necessary restoration of the balance between human action and nature.

A series of 25 rye (Secale cereale L.) inbred lines was tested with respect to three mitochondrial sequence-characterized amplified region (SCAR) polymorphisms. The analysis revealed a close association between the marker-determined mitotypes and plasmotypes (cytoplasm types known from breeding data) represented by the inbreds. The mitochondrial markers also confirmed normal (N-) cytoplasmic character of three wild rye species: Secale montanum, S. vavilovii and S. kuprijanovii. For 186 plants from open-pollinated cultivars of Turkish and South American origin, cytoplasm identification was performed with the use of crossing with double non-restoring tester. In 77 plants the normal (N) cytoplasm was detected, and for 63 of these the PCR analysis was performed producing results which were consistent with the genetic data based on testcrossing and phenotype assessment. The mitochondrial markers also confirmed a presence of sterility-inducing cytoplasm in the remaining 109 plants. Moreover, the markers allowed for differentiation between Pampa (P-) and Vavilovii (V-) cytoplasmic individuals. For 60 plants the latter results were verified using crosses with a line maintaining P-cytoplasmic sterility and acting as a restorer of the V-cytoplasm. For two of these plants contradicting results were produced with the applied methods of cytoplasm identification and the basis of this discrepancy is discussed. Regardless of the identification method, widespread occurrence of a sterility-inducing cytoplasm was revealed, especially in South American populations.
