“…The "niche" available in corn and soybean based rotations to establish legume cover crops after a summer annual is small. In Northern cropping systems, the opportunity to include late-season legume cover crops is greatly enhanced with the inclusion of winter wheat or spring wheat (Triticum aestivum L.) in the rotation and no-till seeding systems [51,52]. Legume cover crop can be grown in a relay cropping system where the legume is frost seeded under winter cereals or grown as a companion crop with spring cereals [35,[53][54][55][56] (Figure 1).…”

Abstract:In light of the environmental challenges ahead, resilience of the most abundant field crop production systems must be improved to guarantee yield stability with more efficient use of nitrogen inputs, soil and water resources. Along with genetic and agronomic innovations, diversification of northern agro-ecosystems using inter-seeded legumes provides further opportunities to improve land management practices that sustain crop yields and their resilience to biotic and abiotic stresses. Benefits of legume cover crops have been known for decades and red clover (Trifolium pratense) is one of the most common and beneficial when frost-seeded under winter wheat in advance of maize in a rotation. However, its use has been declining mostly due to the use of synthetic fertilizers and herbicides, concerns over competition with the main crop and the inability to fully capture red clover benefits due to difficulties in the persistence of uniform stands. In this manuscript, we first review the environmental, agronomic, rotational and economical benefits associated with inter-seeded red clover. Red clover adaptation to a wide array of common wheat-based rotations, its potential to mitigate the effects of land degradation in a changing climate and its integration into sustainable food production systems are discussed. We then identify areas of research with significant potential to impact cropping system profitability and sustainability.

“…Expression of these kinds of genes may result in greater intrinsic physical strength of cell walls and membranes in the landraces from higher latitudes, but also may result in differences in the ability to effectively acclimate to cold temperatures. It previously was shown that wheat lines differ in the response to the onset of low temperatures, such that some lines more rapidly and effectively acclimate to the cold than others [35].…”

“…Although many genomic regions associated with freezing tolerance have been identified and are being exploited in breeding programs, sufficient winter hardiness of available cultivars continues to be problematic [35]. Greater diversity of sources of cold-tolerant genotypes may contribute to further development of freezing tolerance and winter hardiness; wheat landraces from around the world are potential sources of this diversity.…”

Genetic Diversity of Clinal Freezing Tolerance Variation in Winter Wheat Landraces

et al. 2018

Wheat (Triticum aestivum L.) is a major cereal crop grown across a wide range of environments, but its productivity around the world is challenged by various biotic and abiotic factors. Wheat landraces from around the world are a source of unexploited genetic diversity that can be essential for modern wheat-breeding programs in search of resistance to abiotic stresses like freezing tolerance. This genetic diversity study of 553 winter wheat landraces based on single-nucleotide polymorphisms (SNPs) revealed separate clusters of landraces related to the latitude of origin. Linkage block analysis revealed genomic regions with specific alleles skewed towards landraces from higher latitudes, suggesting that migration to higher latitudes resulted in the fixing of specific alleles. Electrolyte leakage was used to measure the tolerance of freezing to −14 • C, −16 • C, and −18 • C of 192 landraces. There was a significant negative correlation between latitude and electrolyte leakage, with an R 2 value of 0.14, (p < 0.0001), in a regression analysis indicating greater freezing tolerance in landraces from higher latitudes. Genome-wide association studies identified regions in chromosomes 4A and 6A associated with higher latitudes and freezing tolerance, respectively. Landraces with freezing tolerance may be useful in developing new germplasm as novel sources of greater cold hardiness.

“…The species has been identified as a high-priority species in need of urgent collection and characterization as a crop genetic resource in part due to its tolerance for low and erratic temperature fluctuations (Kantar et al, 2015). Local adaptation is critical for the introduction of new crop cultivars into habitats that may differ in abiotic factors such as daylength, elevation, heat unit and moisture availability, frost-free period, soil type, nutrient status, or biotic stresses such as pathogens and other pest populations (Allard and Bradshaw, 1964;Fowler, 2012). The extensive range of Maximilian sunflower suggests the species is capable of adapting itself to a wide range of growing conditions and likely harbors useful traits as a genetic resource.…”

Genetic Characterization of Maximilian Sunflower for the Development of a Locally Adapted Perennial Grain Oilseed

2018

Maximilian sunflower (Helianthus maximiliani Schrad.), a crop wild relative of sunflower (Helianthus annuus L.), has been identified as a species of interest for the development of a perennial oilseed crop. Knowledge of the diversity, the potential for crop development, and genomic resources of this crop wild relative is limited. To facilitate its use in breeding programs, a baseline characterization of locally adapted germplasm is required to develop informed breeding strategies. Individuals were collected from nine sites in southern Manitoba, Canada, and characterized for phenotypic and genotypic divergence to estimate traits of interest for the implementation of a breeding program in Maximilian sunflower. Genotype‐by‐sequencing was used to characterize population genetic parameters and identify candidate single nucleotide polymorphisms (SNPs) associated with phenotypic divergence and environmental differences between collection sites. Candidate SNPs associated with frost‐free period, temperature during the primary vegetative growth period, elevation, soil CaCO3 equivalent, days to anthesis and capitulum size were identified and may be useful for the improvement of H. maximiliani and crop species related to cultivated sunflower. Associations between temperature, population structure, and overall plant size were also identified, suggesting phenotypic divergence across a local temperature gradient. The sampled Maximilian sunflower populations exhibited a high degree of polymorphism, low levels of inbreeding, and a highly heterozygous genome at the local scale, traits that favor the establishment of locally adapted germplasm pools. There appears to be sufficient variation to make selections for agronomic traits in local germplasm of Maximilian sunflower to support its development as a perennial oilseed.
