Question

explain the role of biotechnology in the plant breeding

Answer 1

ROLE OF BIOTECHNOLOGY IN PLANT BREEDING:

⏩One major aspects of biotechnology is the practice of growing plant cells and tissue in a suitable culture medium under control laboratory conditions called $tissue \:culture$

⏩The basics for tissue culture is the $totipotency$ of plant cells defined as the capacity of a cell to differentiate into an new organism tissue culture is extensively used for :
1) large scale propagation of medicinal and ornamental plants
2) propagating crops and forest plants
3)developing disease free plants
4)extraction of many useful metabolites .

⏩ Modification of genes in a plant instead of randomly mixing jeans as in conventional plant breeding a specific gene responsible for desired rate it selected and introduced directly into the new plant variety called $gene\: modification$.

⏩ RecombinantDNA technology involves manipulation of genetic material of an organism and the laboratory conditions the DNA containing the desired gene is isolated from a cell of its normal occurrence and transferred into a new host cell with the help of a career DNA called$vector\: DNA$

Answer 2

Role of Bio-technology in plant breeding

O It helps in vegetative propagation .

⇒ Bio - technology helps in asexual reproduction of plants or artificial reproduction of plants .

⇒ The benefits of vegetative propagation are as follows :-

(i) It is economical .

(ii) It leads to better growth of new plants .

(iii) It is environment friendly .

(iv) It helps in generating employment .

(v) It produced more seeds and efficient offspring plants.

(vi) It is hence a method of afforestation .

There are various kinds of propagation and it is helpful in plant breeding .

O Bio - technology helps in nutrition of plants

⇒ The plant which will breed requires care and proper nutrients to produce the best offspring .

⇒ This is achieved by bio-technology.

⇒ Proper care and supply of efficient nutrients  helps in better breeding and better production .

O It produces the desired plant

⇒ Bio-technology helps in producing the desired plant type .

⇒ In order to get a hybrid plant , we have to make a cross breed between fully recessive and fully dominant plants .

⇒ Thus it is very economical and at the same time it does not cause problems to the ecology of the plant life !

O Conservation of plant parts

⇒ Bio - technology helps to conserve tissues , cells and other organs of the plant .

⇒ They are stored in suitable temperatures and is helpful in many industries.

I have explained 4 points if you need more comment ...

Hope it helps !
