Dhaka, May 18 -- Anther culture involves the in vitro culture of immature anthers (the pollenproducing organs of the plant), in order to generate plants from the pollen grains before the fecundation process takes place. As the pollen grains are endowed with only one set of chromosomes instead of two sets as all the somatic parts of the plants are, the pollen-derived plants are haploids (plants endowed with half of the normal number of chromosomes). The haploid plants can afterwards be brought back to the normal diploid status by duplicating their chromosome number through application of chemicals (such as colchicine) or other in vitro techniques. The resulting plants will ...
