The study of collecting samples of alfalfa of different ecological and geographical origin for the collection of dry matter and seed yield on the background of high acidity of soil solution (pH 5,20-5,53) made it possible to identify perspectives for these indicators that can be used in further breeding work. The highest dry matter yield in the average of 3 years of research was obtained from the varieties Vavilovka (Rodnich) (Ukraine) (1.42 kg / m2), Banat (Serbia) (1.36 kg / m2) and Sowing 3022 (Uzbekistan) (1,22 kg / m2) at the yield of the Sinyukh standard of 1.08 kg / m2. Seeds of Zhidrune (Lithuania) (31.9 g / m2), Ferrax 58 (Canada) (29.9 g / m2) and Tibet (Kazakhstan) (28.5 g / m2) with yield of standard 23.5 g / m2 were the best seeds. Particularly noteworthy is Ferrax 58 (Canada), which has significantly exceeded the standard of seed yield and exceeded or exceeded the standard of dry matter during all years of research.

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.

The study of collectible samples of alfalfa of different ecological and geographical origin on the harvest of dry matter and seeds against the background of increased acidity of soil solution (pH 5.20-5.53) made it possible to highlight the promising beyond these indicators samples that can be used in further breeding work. Comparison of the height of alfalfa plants in the first slope and feed productivity in general for 2019 shows that there is no direct correlation between these values. For example, the Galaxie variety, which was itself visopory and exceeded the standard by 12cm, was only in fourth place for the dry crop, and the Olga and Media varieties, which exceeded the standard by 9cm, were only eighth and seventh in the dry material. However, for the selection of varieties that combine these two traits, donors may be samples that behind the harvest of dry matter and the height of plants for three years of research reliably exceeded the standard: Banat, Vavilovka (Rodnichok), Feraks 58, Galaxie and Ferax 28. Not all samples form the maximum of green mass in the first slope, so there is no definite pattern between the height of plants in the first slope and the collection of dry matter for the entire growing season. The highest yield of dry matter on average for three years of research was obtained from varieties Vavilovka (Rodnichok) (Ukraine) (1.42 kg/m2), Banat (Serbia) (1.36 kg/m2) and Posevnaya 3022 (Uzbekistan) (1.22 kg/m2) at the harvest of the Sinyuha-standard grade 1.08 kg/m2. The best in seed productivity were samples of Jidrune (Lithuania) (31.9 g/m2), Feraks 58 (Canada) (29.9 g/m2), Tibet (Kazakhstan) (28.5 g/m2), Radoslawa (Ukraine) (28.2 g/m2), Kishvardi 27 (Hung.) (27.7 g/m2), Olga (26.5 g/m2) and Vavilovka (Rodnichok) (Ukraine) (26.2 g/m2) with a yield of standart of 23.5 g/m2. Particular attention is paid to the variety Ferax 58 (Canada), which for all the years of research reliably exceeded the standard for seed harvest and was at the level of the standard or exceeded it in the yield of dry matter. Further breeding work will use samples that reliably exceeded the standard for the average of three years of research for the collection of dry matter and the seed crop respectively: Ferax 58 (10% and 27%), Radoslawa (7% and 20%), Olga (11% and 13%), In addition, these samples exceeded the standard for plant sisoin in the first slope in 2019 by 31%, 11%, 8% and 55%, respectively. Key words: alfalfa sowing, selection, sample, variety, dry matter crop, seed harvest.

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.

The article presents results of study of biological features of pannonian clover 'Snezhok' (created in the Federal Agricultural Scientific Center of North-East) at long-term use of a reproduction nursery (2011 sowing) for seeds. The soil-climatic conditions of research, the used material and assessment methods are described. The duration of periods of above-ground mass formation, height of plants, structure of stand and seed yield are determined. An elongation of the period from regrowth to the beginning of flowering with increasing of the stand's age was noted. The height of plants, yield of green mass and dry matter in the phase of head and seed ripening increased with the age of the grass stand. An increase in the number of generative stems, heads and mass of seeds per head was also observed. The level of seed productivity of pannonian clover depended more on the age of the grass stand than on the weather conditions of the growing season. We found that the potential seed productivity in favorable years can reach 8.48 kg/ha, while the actual seed yield on average over the years of research was 1.29 kg/ha, with fluctuations from 0.71 (2017) up to 4.63 kg/ha (2015).

AbstractSeveral biotic and abiotic stresses significantly decrease the biomass accumulation and seed yield of sesame crops under rainfed areas. However, plant growth regulators (such as Paclobutrazol) can improve the total dry matter and seed production of the sesame crop. The effects of the paclobutrazol application on dry matter accumulation and seed yield had not been studied before in sesame under rainfed conditions. Therefore, a two-year field study during 2018 and 2019 was conducted with key objectives to assess the impacts of paclobutrazol on leaf greenness, leaf area, total dry matter production and partitioning, seed shattering, and seed yield of sesame. Two sesame cultivars (TS-5 and TS-3) were treated with four paclobutrazol concentrations (P0 = Control, P1 = 100 mg L−1, P2 = 200 mg L−1, P3 = 300 mg L−1). The experiment was executed in RCBD-factorial design with three replications. Compared with P0, treatment P3 improved the leaf greenness of sesame by 17%, 38%, and 60% at 45, 85, and 125 days after sowing, respectively. However, P3 treatment decreased the leaf area of sesame by 14% and 20% at 45 and 85 days after sowing than P0, respectively. Compared with P0, treatment P3 increased the leaf area by 46% at 125 days after sowing. On average, treatment P3 also improved the total biomass production by 21% and partitioning in roots, stems, leaves, capsules, and seeds by 23%, 19%, 23%, 22%, and 40%, respectively, in the whole growing seasons as compared to P0. Moreover, under P3 treatment, sesame attained the highest seed yield and lowest seed shattering by 27% and 30%, respectively, compared to P0. This study indicated that by applying the paclobutrazol concentration at the rate of 300 mg L−1 in sesame, the leaf greenness, leaf areas, biomass accumulation, partitioning, seed yield, and shatter resistance could be improved. Thus, the optimum paclobutrazol level could enhance the dry matter accumulation and seed production capacity of sesame by decreasing shattering losses under rainfed conditions.

Sulphur is a component of plant amino acids, proteins, vitamins, and enzyme structures which influence the productivity of oil seed and total oil content. The experiment was conducted to find out the effect of sulphur on the seed yield and oil content of sesame in Bangladesh. The experiment comprised three varieties of sesame viz. Binatil-2, Binatil-3 and BARI Til-4 and six levels of sulphur (S) viz. 0, 10, 20, 30, 40 and 50 kg S ha–1. The experiment was laid out in a randomized complete block design with three replications. Dry matter production, crop characters, yield components, seed yield and oil content were significantly influenced by variety, level of sulphur and their interaction. The highest dry matter production plant–1 at 50 DAS (17.56 g), plant height (101.3 cm), number of branches plant–1 (3.66),  number of pods plant-1 (41.56), number of seeds pod-1 (58.83),  seed yield    (747.2 kg ha-1), stover yield (2243.0 kg ha–1) and oil content (40.03%) were obtained in BARI Til-4 while the corresponding lowest values of all parameters were recorded in Binatil-2. In case of sulphur application, the highest dry matter production plant–1 at 50 DAS (20.81 g), plant height (109.7 cm), number of branches plant–1 (3.87),  number of pods plant–1 (46.13),  number of seeds pod-1 (56.67),  seed yield (800.0 kg ha–1), stover yield (2787 kg ha–1 ) and oil content (43.97%) were obtained when crop was fertilized with 30 kg S ha–1 while the lowest seed yield (502.2 kg ha–1), stover yield (1550.0 kg ha–1) and oil content (32.80%) were obtained in control (0 kg S ha–1). BARI Til-4 fertilized with 30 kg S ha–1 produced the highest dry matter plant–1 at 50 DAS (24.80 g), number of pods plant–1 (51.13), seeds pod–1 (62.0) and seed yield (1011.0 kg ha–1). The highest oil content (43.97%) was also recorded in BARI Til-4 fertilized with 30 kg S ha–1, which was as good as that of BARI Til-4 fertilized with 40 kg S ha–1. Therefore, BARI Til-4 fertilized with 30 kg S ha–1 can be considered as a promising practice in respect of seed yield and oil content of sesame in Bangladesh. J. Bangladesh Agril.

Progenies from a five-genotype diallel cross in Russian wild ryegrass, Elymus junceus Fisch., were studied to assess the pattern of genetic control for F1 seed weight and a number of seedling and adult plant characters. Variation in F1 seed weight was largely determined by the maternal parent, but some control by the pollen parent was apparent. Of the seedling characters, days to emerge, rate of leaf appearance, rate of tiller appearance, and seedling dry matter yield, only days to emerge showed additive variance which is amenable to direct selection. The other three characters could be most easily exploited by a recurrent selection program. The adult plant characters, date of inflorescence appearance, P content of the forage, and organic matter digestibility indicated strong additive control which is amenable to direct selection. Dry matter yield and seed yield also showed strong additive control which was accompanied by specific combining ability and weak maternal effects suggesting good progress should be possible by direct selection methods but crossing the selections in a diallel fashion prior to formation of synthetics might be desirable. The seedling characters, rate of leaf and tiller appearance and seedling dry matter yield were interrelated and associated with adult plant yield, thus offering the possibility of screening seedlings for these characters in a recurrent selection program for improved forage or seed yield.
