Cotton Breeding in the View of Abiotic and Biotic Stresses: Challenges and Perspectives
Annotatsiya
Global climate change manifested in average annual temperature rise and imbalance of most natural factors, such as changes in annual mean rainfall, air humidity, average temperature of cold and warm months, soil quality, etc., lead to climatic zones displacement. All these have a significant impact on agricultural production in total, including cotton growing. Cotton is one of the most important technical crops in the world. However, it is very sensitive to environmental changes. The influence of abiotic stresses (high temperature, changes in the mean rainfall and soil salinity) causes a dramatic decrease yield of this crop. Moreover, temperature anomalies and climatic zones displacement cause a change in the area of pathogens and pests distribution, which also reduces the cotton yield. One of the possible ways to increase the cotton yield under the influence of abiotic and biotic stresses is the development of new resistant varieties, using both classical breeding methods and genetic engineering achievements.
