प्रश्न
Which of the following represents the primary objective of genetic engineering for abiotic stress tolerance in crops?
विकल्प
To increase the speed of plant growth and development
To eliminate the need for crop irrigation entirely

उत्तर
Abiotic stress tolerance in genetically modified crops is engineered to enable plants to survive and thrive under harsh environmental conditions that would otherwise damage or kill conventional varieties. These conditions include extreme cold, prolonged drought, high soil salinity, and excessive heat. By developing stress-tolerant cultivars through genetic engineering, farmers can grow crops in previously unsuitable environments and maintain yields despite adverse climate conditions.
