Question

needs for crop variety improvement

Answer 1

1- for better production
2- to cope up with increased population demand
3- for producing disease resistant crops
4 - for getting the resistance from abiotic factors

Answer 2

In order to meet the demands with limited resources, we need to apply a greater effort. Crop variety improvement, crop production improvement and crop protection management are three major ways to improve food crops production.

Crop variety improvement is the primary step to improve food crop production. Development of crop variety with desirable traits is the goal of this method. The list of desirable traits includes 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
•Gene Incorporation
