Question

Technology that involves purposeful manipulation of plant species for the development of high yielding and disease-resistant varieties are______________

• A. Green revolution
• B. Plant breeding and introduction
• C. Conventional plant breeding
• D. Hybridization and mutation breeding

Answer 1

The correct option is D Hybridization and mutation breeding

• Hybridization is defined as the process of interbreeding between two individuals of different plant species to obtain a hybrid that contains the genes of both the parent species due to genetic recombination.
• The process of developing a new variety by changing the genome through X-ray or UV radiation is known as mutation breeding. It is a quick method to obtain genetic variation.
• These are the two techniques that can be used for the development of the plant variety which gives high yield and resistance to diseases.

Thus, the correct answer is option D.
