“…Resistance to crown rust is of specific interest as its prevalence is expected to increase with climate change and Nordic materials have been found to be very susceptible (Østrem, Asp, Ghesquière, Sanada, & Rognli, ). Screening of such exotic materials of diverse origin is currently being carried out under field conditions across the northern region as part of the Nordic Public Private Partnership for pre‐breeding in perennial ryegrass with the aim of selecting the most promising material for introgression and recombination in future breeding programmes for the region (Rognli et al., ).…”

In northern countries, Lolium perenne L. generally survives poorly when grown inland and north of 60°N because of extensive winter damage. With the projected future climate change, it could become a promising option for improving production efficiency of the agricultural sector in these regions. Here, we compare the biomass production potential of cultivars of diverse origin across five locations stretching from Estonia to Iceland over a period of three harvest years, and their freezing tolerance under artificial conditions. The aim was to relate the observed pattern of adaptation to the geographic origin of the cultivars and their response to prevailing agroclimatic conditions. Significant interactions were observed between cultivars and test environments (locations × years), and significant interactions between cultivars and years were detected at four of the five locations. Models of joint regression, additive main effects and multiplicative interaction (AMMI) and factorial regression using several agroclimatic indices showed that cultivars developed in northern countries showed greater yield potential across the test environments and were, thus, generally better adapted than cultivars from Central Europe. Diploid cultivars were more frost tolerant than tetraploid cultivars giving them an advantage in locations which were characterized by low temperatures during the hardening period in autumn and mild and rainy winters, such as at the Icelandic location. Only a few cultivars showed general adaptability to the environmental conditions at the test sites, the most stable cultivar being an admixture of diploids and tetraploids. In future breeding, the best strategy would be to hybridize cultivars developed in northern countries with more exotic materials that combine high yield potential, adequate winter survival and superior disease resistance under northern conditions.

“…Although these results were obtained by studying cultivar responses to the climate of Finland, which is rather continental, TA B L E 1 Requirements of plant materials and associated breeding goals for adaptation to and mitigation of climate change effects (modified from Ergon et al, 2018) they are valid for most Nordic and Baltic regions. An example of how diversity can be increased is the intra-specific diversification by introgressing exotic germplasm into the adapted gene pool to improve northern adaptation of perennial ryegrass (Lolium perenne L.), which is the main objective of the Nordic pre-breeding project described below (Rognli et al, 2018).…”

The global climate change is the most important challenge for breeding of forage crops in the near future. The main climate change effects are higher average temperatures, greater climate variability with extreme events, changing precipitation patterns, drought and temperature stress, more wind, less snow cover in continental regions giving more direct frost and ice encasement, and increased CO 2 content in the atmosphere (Ergon et al., 2018;Olesen et al., 2011).This will create new types of abiotic and biotic stresses, requiring increased efforts in breeding new cultivars with improved adaptation to the new climatic conditions. Warming is more rapid in northern regions than the global average, with the largest increases during late autumn, winter and spring. These climate changes will most likely improve the conditions for forage production in these regions, owing to the longer (1-3 months) growing seasons with milder and rainier autumns and winters (Olesen et al., 2011). However, it will be

“…Perennial ryegrass is known to be susceptible to winter injury in temperate growing regions, which limits its distributional range and reduces both stand persistence and biomass production (Rognli 2013;Goslee et al 2017). The potential for such improvement is inhibited by a lack of genetic variation for winter-hardiness (Rognli et al 2018), the polygenic nature of the trait (Thomashow 1999), and unpredictable winter stress in field screenings due to annual climate variation (Rognli 2013). Waldron et al (1998) evaluated 243 half-sib families derived from a top cross between a winter-hardy population, 'NK-200', and a large sample of turf-type individuals.…”

Perennial ryegrass (Lolium perenne L.) is a cool-season grass valued for its grazing characteristics and nutritive value. MSP3984 and MSP4029, breeding populations selected for winter-hardiness, were evaluated for biomass and nutritive value in monoculture and grass-alfalfa mixtures (Medicago sativa L.). Plots were sampled at conventional hay harvest intervals at three Minnesota locations for two production years, 2017 and 2018. Persistence was evaluated in the spring of the third year, 2019. MSP3984 and MSP4029 were compared to commercial cultivars of perennial ryegrass, meadow fescue (Festuca pratensis Huds.), tall fescue (Festuca arundinacea Schreb.), and orchardgrass (Dactylis glomerata L.). Location and year-by-location effects largely influenced grass monoculture yields (p<0.001) and botanical composition of mixtures (p<0.001). In general, perennial ryegrass monocultures yielded less and were less persistent (p<0.05) compared to the other cool-season grasses.Biomass, nutritive value, and persistence did not differ among MSP3984, MSP4029, and the perennial ryegrass check 'Remington'. However, MSP4029 was less competitive in grassalfalfa mixtures than 'Remington' (p=0.01). Perennial ryegrasses had lower NDF This article is protected by copyright.

Perennial ryegrasses also had lower ADF values on average than the other grasses, but cultivar effects were influenced by a year-by-location interaction (p=0.02). This research reinforces 1) the importance of evaluating cool-season forage grasses across latitudinal and precipitation gradients, 2) the value of grass-legume mixtures for yield stability compared to monocultures across locations and production years, and 3) the sustained need to improve forage production and persistence of perennial ryegrass for cold environments.
