“…In this study we verify distinct responses between wheat cultivars, under two cycle life and contrasting environments, according (Rakašćan et al, 2019) this fact occurs mainly by impact of different agro-ecological conditions they were submitted. So the recognition of morphological and physiological characters and traits that affecting the drought tolerance (the ability of a plant to survive under on water restriction) are important for improvement of wheat productivity under inhospitable conditions, where the severity, frequency, and duration of drought stress are essential factors for choosing the place of cultivation and selection of genotypes (Mohammadi and Abdulahi, 2016).…”

The Cerrado is an important agricultural region for the production of food, feed and (bio)fuel, with great potential for the cultivation of tropical wheat (Triticum aestivum L.). However, it is necessary to understand how some genotypes of that crop would fit into this biome, as well as to identify possible physiological and chemical markers that may contribute to the selection of the best plant materials. The objective of this research was to evaluate the metabolic, physiological, biometric and productive characteristics of six wheat cultivars, commonly cultivated in the Cerrado of Minas Gerais, through multivariate analysis (Principal Components Analysis: PCA), in order to characterize the performance of these cultivars in the Cerrado conditions, in two years (2016 and 2017). The PCA showed that monosaccharides content (glucose and fructose) and net CO 2 assimilation rate were highly correlated in both years. Significant differences in rainfall between the two years resulted in different responses of the cultivars and their respective metabolic, physiological, biometric and productive behaviour. Furthermore, it was demonstrated that the CD 151 and Bio Sintonia cultivars grew better when exposed to favourable rainfall conditions, whereas BRS 264 and BRS 394 were the cultivars most suited to lower rainfall.

“…Thus, future of wheat breeding relies heavily on scientific advances and application of genetic modification and marker assisted selection as tools for wheat improvement (PRŽULJ and PEROVIĆ, 2005;KÖNIG et al, 2012). In recent years, the scientific community has increasingly focused on selection wheat varieties with higher genetic diversity, adapted to broad spectrum of environmental conditions, biological pest control and soil fertility enhancement (SADIK, 1991;RAKASCAN et al, 2019). In wild wheat relatives and traditional varieties, breeders today often find resistance genes to numerous pests (TANKSLEY et al, 1996).…”

History of wheat cultivation is as long as history of civilization. Adaptation of nature, animal domestication and plant cultivation, enabled transition from nomadism to sedentism 12,000 years ago, portraying the rise of Homo sapiens of today. First civilization, Mesopotamia aroused around 4000 B.C.E, in the riverbanks of Tiger and Euphrates, where carbon-14 dating revealed that tetraploid wild emmer (Triticum turgidum subsp. dicoccoides) was grown. Due to modest cultivation requirements and high nutritional value, wheat quickly spread from its centre of origin throughout the world. Generations of farmers have chosen seeds from plants with best architecture, adapted to local conditions for sowing, striving toward constant improvement of yields. For centuries agricultural production was based on locally adapted wheat varieties of great genetic diversity. Agriculture completely changed its course in mid-XX century as a result of Green Revolution, introduction of high-yielding cereal varieties, chemical fertilizers and pesticides, irrigation and mechanization replacing traditional techniques. The flourishing of agriculture has drastically changed the course of agricultural development and global society. Improvement of agricultural techniques by integrating scientific advancements and knowledge to assimilate environmental factors has tripled wheat yields in last 50 years. Today, wheat, maize and rice, represent staple food for humanity.

“…This would reduce the use of liquid and solid fuels of oil and coal, which, by combustion, release significantly higher amounts of gases that have harmful effects on the ecosystem (greenhouse effect). The importance of using bio-fuels also lies in the fact that many countries do not have large reserves of fossil fuels for their own needs and are forced to procure them in an unstable market (RAKAŠČAN et al, 2019).…”

Biodiesel and biogas are especially important sources of renewable energy in the world and in Serbia. Biodiesel is used as transportation fuel; biogas is used for production of electricity and heat. Soybean (Glycine max L.) grain is the primary source of vegetable protein for food and feed supplements, also accounts for much of the world?s bio-oil supply. Due to the development of new technologies for processing agricultural waste into energy, the rate of increase in the use of alternative fuels is significantly increasing. The aim of this study was to determine the productivity of soybeans and the possibility of obtaining biogas from soybeans in divergent years, 2017-2019. Main effects were monitored, genotypes (G), years (Y) and genotype by years interaction effects (G x Y) and were used for evaluation of soybean genotypes in different environments. Soybean varieties were tested for mass of 1000 grain (MTG), plant height (PH), grain yields (GY) and biogas yield (BY). Stability of grain and biogas yield was determined to select best genotype. Results showed that genotype and years had a significant impact on all measured variables. In all tested years, the biggest GY and BY were at genotypes G1 (2.40-4.49 t ha-1, and 461.00-641.00 m3 ha-1, respectively) and G3 (1.97-4.30 t ha-1; i.e. 447.67-620.00 m3 ha-1). Genotype G2 had statistically significantly lower values for all tested parameters compared to other tested genotypes. Correlation analysis of some chosen traits showed different interdependence between measured variables depending on the year conditions. The results of this study pointed out that among best genotypes for production of grain and biogas were G1 and G3. From the results of this study it can be concluded that G x Y trials are important for evaluation of stability and choosing the most stable genotypes of soybean.
