ANTHER CULTURE AND HAPLOID PLANT
PRODUCTION
All cells
are having chromosome which are having genetic information . Many cells are
having single set of chromosome are haploid structures , some are having two
set of chromosomes , and others may be
having three or four are triploid and tetraploid respectively.
N=
SINGLE SET OF CHROMOSOMES I.e HAPLOID
Gametic cells of
species are called haploid cells which may be female gametic structure[ovum or
egg] or may be male gametic structure[anther in plants and sperms in humans .
production of haploid is called haploid production. Haploid cells i.e gametes
having a single set of chromosome.
When the haploid plant chromosome is doubled , normal
chromosome no. of a particular species are obtained are called diploid plants
these are homozygous in nature . for obtaining diploid plant from haploid plant
using colchicine .
haploid plants only in nature generated from unfertilized egg
or ovum, but in laboratories we can
produced haploid plant via using male and female gametes . anther and ovary
both are the sexual part of any flower of angiosperm plants which are producing
pollengrain[ male gamete] and when anthers are cultured in a suitable medium to
producing a new plant called anther culture .
GUHA AND
MAHESHWARI developed this technique in
[1984] .used Dhatura innoxia for anther
culture .
Haploids are also can be formed by using ovaries and ovules.
Firstly this techniques was used to produced haploid of DATURA. This technique helpful for instantaneous
expression of mutations and quick formation of pureline.
