Sunflower Breeding for Resistance to Abiotic and Biotic Stresses
Due to a specific structure of its main organs (root, stem, leaves, and head), sunflower can be successfully grown on marginal soils and in semiarid conditions, and it is more resist‐ ant to abiotic stresses, than other field crops. Unfortunately, it is very sensitive to biotic stresses. In sunflower breeding for resistance to abiotic stresses, the greatest progress has been made in selection f...
متن کاملBreeding for abiotic stresses for sustainable agriculture.
Using cereal crops as examples, we review the breeding for tolerance to the abiotic stresses of low nitrogen, drought, salinity and aluminium toxicity. All are already important abiotic stress factors that cause large and widespread yield reductions. Drought will increase in importance with climate change, the area of irrigated land that is salinized continues to increase, and the cost of inorg...

متن کاملGenetic Engineering and Mutation Breeding for Tolerance to Abiotic and Biotic Stresses: Science, Technology and Safety
Genetic engineering is often presented as a one-step, rapid solution to the improvement of stress tolerance in plants. While it may benefit from but not necessitate, the requirement for backcrossing for gene introgression, it does not reduce the requirement for field trials. The introduction of herbicide and pest resistance into plants has been an applied success and these characteristic singly...
متن کاملBreeding for Abiotic Stress Resistance: Challenges and Opportunities
Recent experimentation with transgenic plants has led to increased salinity tolerance, with emphasis on the areas of ion homeostasis, osmotic regulation and antioxidant protection. A case study of the major challenges and opportunities to improve stress tolerance in plants using salinity is presented. As different abiotic stresses are inter-related (e.g. salinity and osmotic stress), our abilit...
