12 Soybean strains bred by the author were tested with respect to their adaptation to different environments in the period 1975-1977. Better environmental conditions in Przecław (Rzeszów region) than in Radzików near Warsaw have beneficial effect on seed yield and the lenght of vegetation period in tested soybeans. Generaly, tested strains yielded better than population variety 'Warszawska' used as a check. Highest yield was produced by strain M-17/76 - 22,7 q/ha. This strain is already registered as a variety 'Ajma'. Seed yield, fat and protein content are determined by genotype and environmental factors. The negative correlation was found between seed yield, its components and the length of vegetation period. It suggests that selection of early and, at the some time, high yielding varieties can and should be done.

The paper considers modern approaches to the zoning of territories and the selection of people for life in extreme environmental conditions, taking into account modern geopolitical challenges. It is shown that it is possible, based on the allostasis concept, to conduct not only the selection of persons with a high level of nonspecific resistance, but also to quantify the degree of extremity of environmental factors using the standard represpiration test. Key words: adaptation, extreme conditions, selection, hypoxia, cold, rerespiration, allostatic load.

Приведены результаты оценки быковпроизводителей голштинской породы по молочной продуктивности и воспроизводительным качествам их дочерей. Обработаны данные 563 первотелок и 45 быковотцов. В среднем удой дочерей за 1ю лактацию от разных отцов колебался от 6784 до 7789 кг, по содержанию жира и белка в молоке различий не выявлено. Большинство производителей обладали желательной степенью реализации генетического потенциала. Основной вклад в генетическое совершенствование стада вносят быки Altahessel Sex138929389, Altajupiter Sex 66011448 и ClearEc Altar2 62916235, достоверно увеличивая удой дочерей за 305 дней 1й лактации от 350 кг до 490 кг по сравнению со средними показателями по стаду. Уровень раздоя коров по 1й лактации достоверно обусловливает их дальнейшую продуктивность. У дочерей ClearEc Altar2 отмечена положительная корреляция (0,44) между удоем и белком, а у дочерей Бодо 354239752 (r0,68) между жиром и белком. Отмечены дочери с отрицательной коррелятивной связью между удоем и жиром, это свидетельствует о том, что в этих группах с высокой молочной продуктивностью отбор коров по жирномолочности не обеспечивает повышение белковомолочности. Самый короткий сервиспериод (98 дней) характерен для дочерей Магикон 536522893, наиболее длинный у дочерей Dinom Altatyson 66133528 и Short Cut 3504510619. Используемые быкипроизводители в хозяйстве реализуют свой потенциал в более сжатые сроки, что необходимо учитывать при дальнейшем их закреплении.The results of estimation of Holstein sires based on milk productivity and reproductive qualities of their daughters are presented .The findings of 563 heifers and 45 bullsfathers were processed.on average, the milk yield of daughters for 1 lactation from different fathers ranged from 6784 to 7789 kg, theee were not found any differences in the content of fat and protein in milk.most producers had a desirable degree of realization of genetic potential. Bulls Altahessel Sex138929389, Altajupiter Sex 66011448 and ClearEc Altar2 62916235mainly contribut to the genetic improvement of the herd, significantly increasing yield of daughters in 305 days of the first lactation from 350 kg to 490 kg compared to the average for the herd. The level of milking cows on the 1st lactation reliably determines their further productivity. Daughters of ClearEc Altar2 had a positive correlation (0.44) between milk yield and protein, and daughters of Bodo bull 354239752 (r0.68) between fat and protein. Daughters with a negative correlation between milk yield and fat were noted, this indicates that the selection of cows by fat content does not provide an increase in protein content in these groups with high milk productivity. The shortest service period (98 days) are typical for daughters of Magikon 536522893, the longest the daughters Dinom Altatyson 66133528 and Short Cut 3504510619.sires, used in farming, realize their potential in a shorter time, which should be taken into account in their further consolidation.

Yield and protein content of 100 random selections from single crosses of wheat and barley were determined for three years. Results of each test showed highly significant differences in yield and protein content of selections. There was a highly significant negative correlation between yield and protein content in each test, the values for rpy varying from −.483 to −.806. In general, the relationship was improved when mean values from several tests were correlated. The behavior of individual selections under a wide range of environmental conditions was relatively constant even though wide differences occurred in both yield and protein content of individual selections.

The cultivation area of soybean (Glycine max (L.) Merr) is increasing in Germany as a way to ensure self-sufficiency through its use as feed and food. However, climatic conditions needed for soybean cultivation are not appropriate in all parts of the country. The objective of this study was to determine the influence of solar radiation, temperature, and precipitation on soybean seed productivity and quality in central and south Germany. A multi-factorial field trial was carried out with three replicates at four locations in 2016 and five locations in 2017, testing 13 soybean varieties from the maturity groups MG 00 and MG 000. Considering all the tested factors, “variety” was highly significant concerning protein content (Ø 41.1% dry matter (DM)) and oil content (Ø 19.1% in DM), but not seed yield (Ø 40.5 dt ha−1).The broad sense heritability of protein content was H2 = 0.80 and of oil content H2 = 0.7. Protein and oil content were significantly negatively correlated (r = −0.82). Seed yield was significantly positively correlated with solar radiation (r = 0.32) and precipitation (r = 0.33), but significantly negatively with Crop Heat Units (CHU) (r = −0.42). Over both experimental years, varieties from maturity group MG 00 were less significantly correlated with the tested environmental factors than varieties from maturity group MG 000. None of the environmental factors tested significantly increased the protein or oil content of soybean. In growing areas with heat periods during ripening, protein content tended to be higher than in cooler areas; in areas with high solar radiation during flowering, protein content tended to be reduced.

Background: Blackgram [Vigna mungo (L.) Hepper] is an important pulse crop occupying a unique position in Indian agriculture. Blackgram provides a major share of the protein requirement of the vegetarian population of the country. The crop is resistant to adverse climatic conditions and improves the soil fertility by fixing atmospheric nitrogen in the soil. Phenotypically stable genotypes are of great importance because the environmental conditions vary from season to season and year to year. Stable performance of blackgram genotypes across contrasting environments is essential for the successful selection of stable and high yielding varieties. Methods: A total of seven genotypes of blackgram were evaluated one season (Rabi - 2019) in three environments to study the G x E interaction for three traits.Result: Based on the stability analysis of Eberhart and Russell model, two genotypes viz., MDU 1 and NRIB 002 were found to be stable across the environments for seed yield. These genotypes had high seed yield with a unity regression coefficient and deviation from regression equal to zero.

Two descendant groups of the barley line Hiproly and the parents, Hja c2661 and Hja c4003, were examined for variations in the DBC protein and amino acid contents. The frequency distributions of the DBC protein content in both descendant groups were unimodal and no effect of one gene was seen, even though the high lysine content of Hiproly is caused by one gene (lys). The means of the DBC protein contents in these F5 generations were 19.1 % and 19.0 %. Environmental factors have a great effect on the DBC protein content: environmental variances from the total variances were 93.84 % and 41.54 %. In the lines with the highest DBC protein contents there were generally more basic amino acids, phenylalanine and proline, than in the lines with the lowest DBC protein contents. Therefore, it appears that the lines with the highest DBC protein contents contain much albumins and prolamins. Also, the ratios of basic amino acids to proline indicated that the relationships between albumins and prolamins were nearly the same for all the lines. Thus, the high DBC protein content in many lines is really based on high amounts of albumins and prolamins at the same time. The present study indicated that Hiproly may be better than the Risø 1508 mutant of barley in breeding for the yielding capacity, because the lys gene of Hiproly does not seem to decrease the prolamin content.

Stability of protein and oil content of 13 soybean varieties were examined using linear model across seven locations and during six years. Due to heterogeneity of environments all year/locations was distributed in to two groups, based on achieved yield. Stability of protein content differed in the low and high yielding environments, while average values show only minor differences. In contrast, oil content stability was slightly changed in the low and high yielding environments, while the average oil content were significantly higher in the low yielding environments. Environmental factors influenced the correlation between oil and protein content in soybeans. Negative correlation between protein and oil content was observed only in the high yielding environments, while varieties in low yielding environments lack this well known inverse relation.

Voice over Internet Protocol (VoIP) is a telecommunications technology that is able to pass the communication service in Internet Protocol networks so as to allow communicating between users in an IP network. However VoIP technology still has weakness in the Quality of Service (QoS). VOPI weaknesses is affected by the selection of the physical servers used. In this research, VoIP is configured on Linux operating system with Asterisk as VoIP application server and integrated on a Raspberry Pi by using wired and wireless network as the transmission medium. Because of depletion of IPv4 capacity that can be used on the network, it needs to be applied to VoIP system using the IPv6 network protocol with supports devices. The test results by using a wired transmission medium that has obtained are the average delay is 117.851 ms, jitter is 5.796 ms, packet loss is 0.38%, throughput is 962.861 kbps, 8.33% of CPU usage and 59.33% of memory usage. The analysis shows that the wired transmission media is better than the wireless transmission media and wireless-wired.
