Question

List out some useful traits in improved crops.

Answer 1

Hint:
 Crop variety improvement is the first step to increase the yield of food crops. It helps to develop crops with required characteristics, such as high yield, disease resistance, quality products and responsiveness to fertilizers. It includes hybridization and gene incorporation.

Complete answer:
Some useful traits in improved crop:

- Higher yield: The main goal of improved crop varieties is to increase crop productivity. Develop high-yield varieties.
- High-quality products: improve the quality of food crops. The quality of crops depends on the type of crops. Considering beans and grains, they must have better baking quality. Oil crops should provide high-quality oil.
- Resistance: Develop resistance to biological and non-biological factors. Biological factors (such as insects, parasites, diseases, etc.) and non-biological factors (such as high temperature, low temperature, drought, salinity, etc.) affect crop production. Resistant varieties can withstand these factors and obtain high yields.
- Maturity period: shorten and develop a unified maturity period. The short maturity period of crops can help farmers reduce expenditures for multiple rounds of planting in a short time.
- Adaptation: Improve tolerance and make crops more adaptable to different conditions. Crops can be grown even under different conditions. For example, crops that are tolerant to high-salt soils.
- Ideal agronomic characteristics: agronomic characteristics required for development in crops. This helps to achieve higher output with less expenditure. For example, dwarfing in grains will reduce nutrient consumption without affecting yield.

Note:
 Hybridization: The hybridization of genetically heterogeneous plants is called hybridization. Hybridization may occur between different species (inter-species), between two different species of the same genus (inter-species), or between different genera (inter-genus). Genes are responsible for these characteristics. Therefore, we can improve the quality and quantity of crops by integrating genes with ideal traits.
