The aim of the research was to assess the breeding value of the source material of F. rubra of the lawn direction obtained under conditions of various ecotopes of the south of the Central Russian Upland with a predominance of carbonate substrate. In total, 106 numbers of red fescue of various genetic and geological-geographical origin were evaluated in the experiment: 4 varieties and 102 breeding samples. Tests of the breeding value of the collection numbers were carried out in comparison with the zoned varieties of domestic selection (‘Veselka’, ‘Gostenka’, ‘Iskrinka’) and foreign selection (‘Gondolin’). The forms of F. rubra have been identified, approaching erect in shape, having a high shoot-forming ability, pronounced antocian color of inflorescences, whitish bloom on the leaves, which increases the overall decorative effect of lawn herbage. According to a number of important traits for breeding for seed productivity, the forms selected in natural habitats with a predominance of carbonate substrate have wide limits of variation and can serve as genetic sources of individual breeding traits for obtaining new varieties of lawn management with high seed productivity and decorativeness.

Abstract Collected specimens of Festuca arundinaceae Sherb. (2014-2018). Source material for breeding was obtained as a result of expeditionary studies in the Belgorod region in different ecotopes of ravine and ravine complexes, floodplains of rivers, and technogenic-disturbed lands. Tests of breeding value of selected forms were carried out in comparison with released varieties of Russian (‘Olshanka’, ‘Ivitsa’, ‘Darina’) and foreign breeding (‘Finelawn’, ‘Meandre’). It has been established that the forms selected in natural habitats had wide limits of variation in all basic selection traits - Cv varied from 11.4% for traits ‘number of shoots on 1 plant’ and ‘number of productive shoots on 1 plant’ to 65.4% for the trait ‘color of knots’. Wild populations provide opportunities for selection of such important for selection on seed productivity traits as “number of seeds in one panicle” and “weight of 1000 seeds” - Cv = 12.1 % and 16.1 % accordingly. The results indicate the possibility of using the source material available in the collection to produce new lawn varieties with high seed productivity and ornamental value.

Collecting, exploring and using a suitable, genetically diverse source material with different ecological-geographical origin is a determining prerequisite for the breeding success. The present study was conducted during the 2014-2016 period at theInstituteofForage Crops(Pleven,Bulgaria) with 23 cultivars of white lupine originatingPoland,RussiaandUkraine. It was found a significant genetic diversity among the studied cultivars, which was a good prerequisite for starting a breeding program within the crop. The most favorable combination of a high seed productivity and crude protein content had cultivars ‘Tel Keram’, ‘Pflugs Ultra’, ‘WAT’, ‘Solnechnii’ and ‘Pink Mutant’, whose plants were also characterized by a mass of 1,000 seeds between 15 and 21 g. Genetically, the most distant from each other were ‘Bezimenii 1’ and ‘Pflugs Ultra’ compared to ‘Termis Mestnii’ and ‘Solnechnii’ as well as to ‘Tel Keram’. These cultivars are suitable as genitors for the development of high-yielding white lupine cultivars. Studied traits of pod length, number of seeds in a pod and seeds per plant showed a high positive phenotypic and genotypic correlation with the seed productivity in white lupine. Regarding productivity, it can be rely upon the mass of 1,000 seeds, plant height and number of seeds per plant due to their high total effect on the seed weight per plant.

Epichloë Festucae

Strong creeping red fescue (Festuca rubra subsp. rubra) is a commercially important low-maintenance turfgrass and is often naturally infected with the fungal endophyte Epichloë festucae. Epichloë spp. are endophytes of several cool-season grass species, often conferring insect resistance to the grass hosts due to the production of toxic alkaloids. In addition to insect resistance, a unique feature of the strong creeping red fescue/E. festucae symbiosis is the endophyte-mediated disease resistance to the fungal pathogen Clarireedia jacksonii, the causal agent of dollar spot disease. Such disease resistance is not a general feature of other grass/ Epichloë interactions. E. festucae isolates infecting red fescue have an antifungal protein gene Efe-afpA, whereas most other Epichloë spp. do not have a similar gene. The uniqueness of this gene suggests it may, therefore, be a component of the unique disease resistance seen in endophyte-infected red fescue. Here, we report the generation of CRISPR-Cas9 Efe-afpA gene knockouts with the goal of determining if absence of the protein in endophyte-infected Festuca rubra leads to disease susceptibility. However, it was not possible to infect plants with the knockout isolates, although infection was possible with the wild type E. festucae and with complemented isolates. This raises the interesting possibility that, in addition to having antifungal activity, the protein is required for the symbiotic interaction. The antifungal protein is a small secreted protein with high expression in planta relative to its expression in culture, all characteristics consistent with effector proteins. If Efe-AfpA is an effector protein it must be specific to certain interactions, since most Epichloë spp. do not have such a gene in their genomes.

Each of the species birdsfoot trefoil (Lotus corniculatus L.), timothy (Phleum pratense L.), bromegrass (Bromus inermis Leyss.), orchardgrass (Dactylis glomerata L.), reed canarygrass (Phalaris arundinacea L.) and creeping red fescue (Festuca rubra L.) was grown in the field on 10 plots sampled at weekly intervals in rotation from June 13. Each plot was resampled after 6 weeks and all samples were analyzed for copper, molybdenum and sulfur. In most species, levels of Cu and Mo were highest in the early samplings and decreased with advancing maturity. Second-cut samples tended to be higher in Cu, Mo and S than first-cut samples. The S content was more uniform in the first cycle but increased considerably in the second cycle, especially in reed canarygrass. The ranges in Cu content were 7.4 to 14.1 ppm for birdsfoot trefoil and 3.7 to 11.4 ppm for the grasses. Mo ranged from 1.9 to 8.1 ppm in birdsfoot trefoil and from 1.0 to 6.5 ppm in the grasses. The overall range in S content was from 0.14 to 0.95%. The mineral composition of the crops is discussed in relation to the requirement of ruminants for these three elements.

Tiller Density

Six trials were conducted on commercial seed fields of creeping red fescue (Festuca rubra L. var. rubra) in the Peace region to evaluate the sensitivity of seed production to the method and time of application of N fertiliser. In each trial, 68 kg ha−1 N was applied using three methods (surface-broadcast, granular, ammonium nitrate 34-0-0; foliar/soil spray of 28-0-0 solution N; soil-injected 28-0-0 solution N) at each of three times (fall, early spring, late spring). No statistically significant (P = 0.05) interaction, or main effect, of method and time of N were revealed for seed yield, fertile tiller density or for several seed quality characteristics. Seed yield varied greatly among trials (142 to 1240 kg ha−1) and averaged 566 kg ha−1. The results indicate that there is considerable flexibility in the method and time of application of N fertiliser for seed production of creeping red fescue in the Peace region, provided it is applied before the commencement of vigorous plant growth in the spring.

The paper presents comparative results of Festuca rubra L. seed productivity study in Siberia and Kazakhstan. The authors consider the influence of ecological conditions on the organo-educational process of the species. The authors reveal specific features of plants growth and development at different terms of seeding in different ecological conditions. In the first year of vegetation, plants in all variants undergo two phenological phases - shoots and tillering. Different planting dates make significant changes in the reproductive capacity of plants. In spring plants sowing apical meristem at the end of the growing season corresponds to the IV stage of organogenesis. The following year in spring, shoots of the 2nd, 3rd and 4th orders also become generative. An optimal method of Festuca rubra growing with maximum parameters of seed productivity was determined. It was found out that during spring sowing the maximum yield of seeds (up to 48 g/m) can be obtained for the 3rd year of life of the cereal. For the 4th year there is a slight decrease (45,4 g/m). With the early sowing date - the maximum yield (up to 51 g/m) was obtained only for the 4th year of plant life and a further decrease is observed. During autumn sowing, the first fructification of cereals occurs only in the 3rd year of life and is expressed in the maximum number of shoots and the yield of seeds (68 g/m). Further sharp decrease in such indicators as generative shoots and yields indicates the inexpediency of further preservation of the testes.

Greenhouse Study

A red fescue (Festuca rubraL.)- Kentucky bluegrass (Poa pratensisL.) turf was treated annually with amidochlor {N-[(acetylamino)methyl]-2-chloro-N-(2,6-diethylphenyl)acetamide} at 2.2, 2.8, and 3.4 kg ai/ha, mefluidide {N-[2,4-dimethyl-5-[[(trifluoromethyl)sulfonyl] amino] phenyl] acetamide} at 0.4 kg ai/ha, and ethephon [(2-chloroethyl) phosphonic acid] at 5.6 kg ai/ha for three consecutive years. Recuperative potential of treated turfgrass was determined in the field and in a greenhouse study. Amidochlor and mefluidide treatments injured turfgrass (11 to 64%) four weeks after application. However, turfgrass recovered after eight weeks. Amidochlor at 2.8 to 3.4 kg/ha and mefluidide at 0.4 kg/ha suppressed (75 to 100%) seedhead development. Ethephon at 5.6 kg/ha was ineffective. Turfgrass recovered normally each spring after amidochlor treatments, with no delay in spring green-up. Root length, root weight, and root:shoot weight ratio of the plugs from the greenhouse study were unaffected by three consecutive annual applications of amidochlor, mefluidide, and ethephon. One annual spring application of amidochlor, mefluidide, and ethephon for three consecutive years caused no adverse effects that would limit their use on red fescue-Kentucky bluegrass turf.
