Answer:
We know resources are very limited, but the demand is very high. Thus, the basic reason for variety improvement is to meet the requirements. However, the quality and quantity of the crop produced shouldn’t be compromised due to the limited resource and present scenario. This is why scientist developed different varieties. The different strains should be able to show maximum productivity under any diverse condition. This leads to the idea of improvement of food crops variety. Variety improvement Food Crops
The variety improvement is done for the following reasons.
Higher yield: Crop variety improvement’s main goal is to increase the productivity of the crop. To develop high yielding variety.
Quality product: To improve the quality of the food crops. 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: To develop resistance to both living and non-living factors. 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: To shorten and to develop uniform 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.
Adaptation: To develop tolerance and make crops more adaptable to different conditions. The crops can be grown even in diverse conditions. For example, crops with tolerance to high salinity soil.
Desirable agronomic characteristics: To develop desired agronomic characters in crops. This helps in a higher yield in less expenditure. For example, dwarfness in cereals reduces the nutrient consumption without affecting the yield.
