Abstract:
... The surveys were performed to analyze the adaptive capacity in the spring barley varieties bred at the Rudnitsky Federal Agricultural Science Center of the Northeast (FANC Northeast) for the yield-related traits and the antifungal resistance. The surveys were carried out in Kirov oblast in 2018–2021. Nine in-demand spring barley varieties bred in 1992 to 2021 served as the survey material. Statist ...

Abstract:
... The major impact of both genotypic and environmental factors on grain-filling efficiency of rice (Oryza sativa L.) makes evaluating cultivar’s grain-filling characteristics highly complicated. To assess grain-filling characteristics, the allocation index (Alli) was defined as a novel indicator representing the pattern of resource allocation in panicles. Alli was calculated as the ratio of source o ...

Abstract:
... The world’s increase in rice (Oryza sativa L.) production is not keeping up with the increase in its population. To boost the introduction of new high-yielding cultivars, knowledge is being gained on the genes and quantitative trait loci (QTLs) determining the panicle phenotype. The important are those determining yield of the crop, such as grain numbers per panicle and size and weight of t ...

Abstract:
... Understanding the yield potential and yield-determining factors of recent high-yielding cultivars is essential for further increasing rice yield. In this study, a cross-locational field experiment was conducted across 3 years using ‘Hokuriku 193ʹ (H193), a high-yielding cultivar, at four sites including one in Nagano Prefecture, which is the highest-yielding region in Japan. The highest mean yield ...

Abstract:
... Maize is an important crop for billions of people globally. The existing immature embryo-based regeneration protocol of maize has major limitations due to the non-availability of explants throughout the year, limited durability for culturing, and its laborious nature. Mature embryos, especially in tropical maize, are considered recalcitrant towards tissue culture. Therefore, standardization of a r ...

Abstract:
... Spring wheat (Triticum aestivum L.) yields across the Canadian prairies are rising, however, a yield gap remains between average yield and yield potential, which can be explored further under Prairie conditions. The high rates of nitrogen (N) fertilizer required for current high‐yielding cultivars may increase lodging risk adding to this yield gap. The objectives of this study were to determine th ...

... To generate high-yielding cultivars with favorable fiber quality traits, cotton breeders can use information about combining ability and gene activity within a population to locate elite parents and potential F1 crosses. To this end, in the current study, twelve cotton parents (eight genotypes as female parents and four testers) and their F1 crosses obtained utilizing the linex tester mating desig ...

Abstract:
... Global warming has changed the suitability of areas traditionally planted with crops, raising concerns about cereal security. To investigate the possibilities and constraints of increasing yields by breaking through traditional area plantings of wheat cultivars, a two-year field experiment was conducted in southern and northern locations in the Yangtze River basin (YRB), China (separated by approx ...

Abstract:
... This study provides empirical evidence for the relation between perishability in vertically coordinated supply chains and the market power exercised over smallholders in Nepal. Using survey data from small‐scale farms of tomatoes, ginger, high‐yielding variety paddy seeds, and lentils, we demonstrate how varying levels of perishability affect the degree of market power exercised by contractors and ...
... Identification and selection of cowpea genotypes possessing suitable agronomic attributes is key for cultivar development to increase production. The objective of this study was to evaluate cowpea genotypes using agronomic traits to aid selection and identification of best genotypes for adoption and breeding to develop high-yielding cultivars. Agronomic traits of 20 cowpea genotypes were evaluated ...

Abstract:
... The success of the dwarf breeding of rice, called the Green Revolution in Asia, resulted from increased source and sink capacities depending on significant inputs of N fertilizer. Although N fertilization is essential for increasing cereal production, large inputs of N application have significantly impacted the environment. Transgenic rice overproducing Rubisco has demonstrated increased yields w ...
... Adopting environmentally and economically sustainable rice production systems is essential to achieve better results in terms of yield, financial profitability and eco-efficiency. This study compares the GHG emissions and the financial analysis (based on both costs and gross return and some financial indicators) in eight rice paddy production systems in northern Iran, under the combination of thre ...

Abstract:
... Sugarcane, Saccharum spp. L., is an important commercial crop for its white crystal sugar and biofuel. High production of sugarcane depends on planting high-yielding variety and quality seed cane. Therefore, a field experiment was conducted with the objectives of evaluating the effect of the time gap between seed cane cutting to the planting of sugarcane varieties on growth parameters and yield of ...
... Agricultural production is facing serious threat from various biotic and abiotic stresses specifically under climatic challenges. It is becoming increasingly difficult to fulfill global food demand from limited arable land by cultivating modern cultivars with low buffering capacity. Primitive cultivars and landraces are evidently proven to be rich source of genetic variability as against modern cu ...

Abstract:
... Barley (Hordeum vulgare L.) is one of the major strategic crops in Ethiopia. Average yield is low due to low-yielding varieties, biotic and abiotic constraints. Farmers are concerned with quantity while the malting industries need to ensure quality. There has been a general belief by the industry that two-row barleys are better than the six-row types in terms of quality but farmers are inclined to ...
... With the growth of population, climate change is a threat to global food security. Understanding and identifying appropriate options of cropping systems and management practices at spatial (locations) and temporal (climate change) scale is important and required. A simulation study was carried out on 13 different locations of Senegal with the objectives of (i) assessing impacts of midcentury clima ...

Abstract:
... The marketability of spring wheat (Triticum aestivum L.) across the Canadian prairies is largely dependent on grain protein content. New high‐yielding cultivars require a large investment in fertilizer N to achieve milling quality standards. When high rates of N fertilizer are applied, N use efficiencies tend to decrease, lowering returns on investment. The objectives of this study were to identif ...

Abstract:
... BACKGROUND: Rice (Oryza sativa L.) is the major source of daily caloric intake for more than 30% of the human population. However, the sustained productivity of this staple food crop is continuously threatened by various pathogens and herbivores. Breeding has been successful in utilizing various mechanisms of defense by gene pyramiding in elite cultivars, but the continuous resurgence of highly re ...

Abstract:
... Crop diseases affect crop yield and quality and cause significant losses of total food production worldwide. With the ever‐increasing world population and decreasing land and water resources, there is a need not only to produce more food but also to reduce agricultural greenhouse gas (GHG) emissions to mitigate climate change and avoid land use change and biodiversity loss. Thus, alternative clima ...
