Question

The classical method of plant breeding is ______a) Hybridization
b) Mutation breeding
c) Genetic engineering
d) Tissue culture

Answer 1

Answer:

Tissue culture

Explanation:

The purpose of classical plant breeding is the creation of new lines and varieties with improved agricultural traits such as higher yields, increased tolerance or resistance to diseases and adverse environmental conditions. Tissue culture is a biological research in which fragments of a tissue of plant or animal are transferred into artificial environment that enable them survive and function properly.  

Answer 2

The correct answer is a) Hybridization.

Explanation:

• Hybridization is a technique in which the essential and required traits present in the different lines of plants are brought in a single line of plant by the process of regulated cross fertilization.
• Initially, lines of plants which are homozygous for the particular trait are obtained by the process of inbreeding. This process generates a line of pure breed.
• Next, these pure breed lines are inter-crossed among themselves, (also called Outcrossing) to develop offspring having the desired traits from both the pure inbred lined.
