Abstract The aim of this work was to develop a red clover variety adapted to agro-climatic conditions of Latvia, suitable for different requirements of forage producers, resistant to most widespread diseases and producing high seed yield annually. Medium late ripening diploid red clover variety ‘Jancis’ was created at the LLU Research Institute of Agriculture in long-term work carried out since 1985. After free pollination of best samples of red clover collections from the VIR (St. Petersburg), individual and family selection among hybrids were carried out for approximately 20 years. Finally, best breeding line Nr. 43047 was registered as a variety ‘Jancis’. The variety is characterised by good winter hardiness, high dry matter yield (10-12 t·ha-1) and good persistence in the sward - up to 3-4 years. The variety is characterised by a long stem (90-110 cm) with 8-9 internodes, dark green leaves with a distinctive brighter picture, medium length and width of medial leaflet, and bright pink flower heads. ‘Jancis’ has stable annual seed yield in the conditions of Latvia; under favourable conditions reaching 500- 600 kg·ha-1 seeds. Since 2010, the variety ‘Jancis’ has been included in the common Latvian and EU Plant Variety Catalogue.

AbstractQuinoa (Chenopodium quinoa Willd.) is capable of adapting to multiple environments and tolerating abiotic stresses including saline, drought and frost stress conditions. However, the introduction of quinoa into new environments has disclosed adaptation challenges. The principle factor affecting crop pollination is heat stress at flowering, which leads to sterile plants. To investigate the effect of high temperatures during the sensitive phenological phases, flowering and seed germination, a Danish-bred cultivar (cv. Titicaca) was grown in climatic chambers. Selection of the cv. Titicaca was based on the fact that it is the most extensively used cultivar in the Sahel and Middle East and North African region. The results of this research demonstrated that temperatures exceeding 38 °C hindered seed germination and pollination, and therefore, seed yield at harvest. At 38 °C, seed yield losses were 30%, whilst seed germination percentage declined below 50%. In addition, the results of the present research were compared with field observations from Burkina Faso in order to determine the spatiotemporal suitability of this crop with respect to temperature stress. Although many other abiotic stresses need to be considered when defining crop calendars (e.g. heavy precipitation in July and August), this research proposes the following growing periods to avoid heat-stress conditions at flowering: Sahel (July–September and November–February), Soudano–Sahel (June–February) and Soudanian zone (all year round).

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.

Chickpea (Cicer arietinum L.) is one of the important legumes widely grown for dietary proteins in semi-arid Mediterranean climatic conditions. Thirty-four selected chickpea genotypes were tested under two (winter and late sowing) conditions to assess the genetic diversity for drought tolerance capacity. Factorial experiment in randomized complete block design with three replications was conducted during 2015 and 2016 at the Eastern Mediterranean Agriculture Research Institute Adana, Turkey. Significant differences and reduction was observed amongst the genotypes under stress condition compared to normal one. All traits except seed yield and hundred seed weight in 2015 were higher than those in 2016. Besides, all investigated traits significantly decreased in stress condition experiment compared to non-stress one in both years. It was observed that seven genotypes viz., ICC 1205, ILC 8617, ILC 4567, FLIP 03-21 C, FLIP 03-42 C, FLIP 01-24 C and ENA 8-2 genotypes provide early expressed early vegetative growth stages. Besides, Aksu, Arda, Çakýr, Dikbaþ, EN 808, ENA 8-2, FLIP 03-108 C, ICC 1205 and Seçkin had high seed yield under drought conditions during two years. Therefore, these genotypes can be used as donors of drought tolerance in future breeding program of chickpea.

This research was carried out to determine genotype-by-environment interaction of safflower genotypes tested from 2014 to 2017. Konya, where the research was carried out, is the location with the most irregular and the lowest precipitation in Turkey. In this research, the variance analysis over years and genotypes showed that the main effects on genotypes made by year and genotype-by-year interaction were statistically significant (p<0.01) for all characteristics examined. The climatic conditions, especially the amount and distribution of precipitation, over the years allowed genotypes to perform substantially differently in seed yield and oil content of safflower genotypes. The biplot analysis provided significant advantages in identifying the promising genotypes. The genotypes showed similar patterns of performance across the years, while the amount and distribution of precipitation showed similar patterns. The experimental results revealed that the desired genotypes in terms of both stability and high yield, such as G?kt?rk, G7, and Din?er, G5 and G9 and oil content, such as G?kt?rk, Balc?, and Linas, existed. In comparison to oil content, seed yield was more sensitive to environmental factors.

Southern European countries have milder climatic conditions that differ from their colder northern counterparts, which greatly influence indoor ventilation strategies. The relation between a building’s airtightness and the air change rates remains a topic to be fully tackled in these countries, since natural ventilation is very frequent. In this work, the ventilation and airtightness of a case study were analyzed in-depth to support a discussion on this topic. CO2 concentration decay and blower-door measurements were used to characterize the infiltration and ventilation conditions of the case study. The case study represents a common Portuguese situation, with highly permeable envelopes, combined with highly variable air change rates. Transient simulations were carried out for the comparison of scenarios where different configurations of possible air paths were analyzed. The simulations included both natural and mechanical ventilation scenarios. An air sweeping effect from bedroom to bathroom only occurred when the mechanical extraction ventilation (MEV) was on. Different air leakage path configurations resulted in substantial offsets, up to 63%, of the air change rate (ACH) due to natural occurring forces. The results confirmed that the relation between airtightness and air change rates should be carefully analyzed in southern European countries, as indoor air quality, comfort of occupants, and energy efficiency are highly influenced by the considered variables.

Relevance. In Uzbekistan, especially in the south of the republic, in recent years, early ripe varieties of onion Sumbula, Ravnak, Bakhora have become widespread. However, the technology of seed production of early maturing varieties has not been developed. In this regard, several studies were carried out to identify the optimal time for planting the mother plants of the early maturing onion variety Sumbula by using the favorable climatic conditions of southern Uzbekistan.Material and methodology. The material for the research was the early ripe onion variety Sumbula, bred by the Research Institute of Vegetable and Melon Crops and Potatoes. The studies were carried out according to the Methodological guidelines for the ecological testing of vegetable crops in the open field etc. The dates of seed planting were studied.Results. Studies have shown that the highest seed yield (0.97 t/ha) was obtained in the early autumn planting of mother plants on September 1. It was 20% more than in the control variant – September 15. At later planting dates, the seed yield decreases sharply.When mother plants were planted on October 30, the seed yield was only 0,46 t/ha, or 59.7% of the control.The yield of onion seeds increases, mainly due to the more powerful development of plants during early autumn planting – the formation of large leaves, inflorescences, and additional arrows. The more large and powerful leaves, the more plants have the ability to synthesize plastic substances in the process of photosynthesis and accumulate a high yield.

Indian mustard (Brassica juncea L. Czern) cultivation is suggested for regions with short seasons and low rainfall. Although there have been many studies conducted on agronomic production of mustard in Iran, the information regarding the interactive impact of cropping seasons and nitrogen fertiliser on growth characteristics and yield quality of mustard plant is still insufficient and requires further investigation. This study focused on the possible implications of different cropping seasons and different nitrogen levels on selected agronomic traits in mustard. In this experiment, five different doses of nitrogen and two sowing periods were used to assess for their combined effects on the growth parameters, seed yield and agronomic characteristics of mustard in the semi-arid climatic conditions of Takestan. The results revealed that cultivation seasons and nitrogen rates had a significant effect on plant height, biomass yield, number of siliques per plant, seed oil content and seed yield.
