Question

Shoot tip culture are preferred for inter national exchange of germplasm because

• A. They are more stable.
• B. These are easier to regenerate.
• C. They produce virus free clone plants.
• D. All the three statements are correct.

Answer 1

The correct option is D All the three statements are correct.

Germplasm is vital resource in generating new plant types having desired traits that help in increasing crop production and thus improve the level of human nutrition. It fuels all the activities of modern agriculture - research, improvement and production. This vital need of plant genetic resources traditionally catered to the potential use of plant species within its primary and secondary genepools. With the ever increasing need for more food and better nutrition, crop improvement has become the axle of the wheel of human life. The plant breeders need more diverse germplasm so that the acquisition of superior varieties by importing them from other areas has now become absolutely necessary. Shoot tip culture are preferred for inter national exchange of germplasm because they are easy to regenerate, most stable and they are virus free clones. Thus, option D is correct.
