Question

Androgenic haploid culture is used for all, except
1.Obtaining virus free clones of plants
2.Maintaining pure lines
3. In mutation breeding
4.Producing seedless varieties​

Answer 1

Answer:

Haploid plants are useful in plant breeding. Haploids can be used to generate genetic homozygotes by one generation doubling of chromosomes using colchicine. Colchicine prevents spindle formation. Hence, the chromosome number can be easily doubled using colchicine. Anther culture is done for production of haploids because anthers contain haploid microspores (pollen grains) which can be used to generate new plants. Such haploids are called androgenic haploids because they have been developed from male gamete producing spore, i.e., pollen grain or microspore.

Explanation:

so the answer is

in mutation breeding

Answer 2

Explantation :- { (3) In mutation breeding }...

ANSWER :- Haploid plants are useful in plant's breeding . Haploids can be used to generate genetic homo zygotes, One Generations doubling of Chromosomes using Colchicine . Hence, Such haploids are Called is the Androgenic haploids . Because they have been developed from Male gamete producing spore,

Ex:- Pollen grain or and the
