Answer 2

Answer:

Here is the answer for your question:

Food Crops

Food crops are crops that contribute to the world’s major food supply. They comprise grains, seeds, nuts, vegetables, fruits, legumes, spices, herbs, beverages, etc.

Grains are a major source of human food. They serve as a staple food for the majority of population. These include rice, wheat, maize, barley, etc.

Legumes and dried beans have a longer shelf-life and are economical. Thus, they can be used in seasons when food is scarce.

Seeds and nuts are the powerhouses of energy and a concentrated form of food.

Herbs have a strong flavour. These mainly comprise leaves, stems, flowers, roots and seeds.

Methods Of Crop Variety Improvement

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. We can raise different strains of food crops with desirable traits naturally as well as scientifically. Two of them are as follows:

Hybridization

The crossing of genetically dissimilar plants is referred to as hybridization. Hybridization may take place between different varieties(intervarietal), between two different species of the same genus(interspecific) or between different genera (intergeneric).

Gene Incorporation

Genes are responsible for the traits. Thus, we can improve crop quality and quantity by incorporating the genes with desirable traits. This method is more scientific and results in genetically modified food crops.

Food Crops

Crop production is more like a business in many countries. Thus, the strains we develop must be economically profitable. The new varieties should be able to produce maximum quality and quantity under different conditions and regions. Hence, we need to be very selective about seeds for its acceptance.
