Question

Name any three factors for which crop variety improvement is done and explain each of them.

Answer 1

• Crop variety improvement is the primary step to improve food crop production.
• It helps in the development of crops with desired traits such as high yields, disease resistance, quality product and response to fertilizers.
• Higher yield: Crop variety improvement’s main goal is to increase the productivity of the crop.
• Quality product: The quality of the crop depends on the type of crop. Considering the pulses and grains, they must have better baking quality. Oil crops should give quality oil.
• Resistance: Biotic factors like insects, parasites, diseases, etc. and abiotic factors like hot, cold, drought, salinity, etc. affect crop production. Resistant variety can withstand these factors and give a high yield.
• Maturity period:. The short maturity period of crops helps farmers in multiple rounds of cultivation in less expenditure during a short period. Also, the uniform maturity of crops helps in easy harvesting.
• Thus, the overall variety of improvement makes the situation more profitable.
