Based on the search results, here are the phenotypic characteristics that have been selected for the production of stains suitable for modern agricultural purposes:

Increased Yield and Efficiency

Higher crop yield per unit area: The most obvious trait, aiming to produce more food from the same amount of land.

Larger seeds: Improves the establishment and success of the next generation of plants.
Increased determinacy: Reduces the loss of seeds before harvest.

Reduced lodging: Allows the crop to maintain an upright position throughout the growing season, preventing losses due to bending or falling over.

Improved response to fertilizers: Plants can utilize applied fertilizers more effectively, reducing waste and potentially increasing yield.

Enhanced nutrient use efficiency (NUE): This includes being more efficient in utilizing nitrogen and phosphorus, minimizing waste and environmental impact.

Enhanced Resistance and Tolerance

Resistance to diseases: This can be either qualitative (complete resistance to specific pathogens) or quantitative (partial resistance controlled by multiple genes). This reduces crop loss and reliance on chemical pesticides.

Increased tolerance to insect pests: Reduces crop damage and the need for pesticides.
Increased tolerance to herbicides: Allows for more effective weed control, potentially reducing competition for resources and leading to higher yields.
Increased tolerance of environmental pressures (abiotic stresses): This includes:
Drought tolerance: Enables plants to withstand and recover from periods of water scarcity.
Heat tolerance: Reduces damage from high temperatures.
Cold tolerance: Minimizes damage from low temperatures.
Salinity tolerance: Improves growth and productivity in high salt concentration soils.
Weed competitiveness: Enables crops to better compete with weeds for resources, reducing yield loss.

Improved Quality and Sustainability

Improved quality: Encompasses increased nutrition, flavor, and overall aesthetic appeal.
Longer storage period: Reduces post-harvest losses and extends the shelf life of crops.
Early maturation: May help in avoiding certain stresses or enable multiple crop cycles in a season.

These characteristics are crucial for developing crop varieties that can meet the demands of modern agriculture, including global food security, sustainability, and climate change adaptation.
