Abstract:
In nature, pollen selection plays major role in evolution than ovule selection. Pollen selection can be defined as “application of selection pressure or stress to pollen grains (Gametophytic phase), so that, only those pollens carrying the desirable allele for the respective trait will be selected for fertilization, there by increased transmission of desirable alleles for targeted traits from gametophytic to succeeding sporophytic generation is achieved.The principle behind pollen selection is pollen competition. Whenever there is competition among the pollen grains lying on same stigma, only those pollens carrying the desirable alleles will be allowed for fertilization.Pollen selection is more effective than sporophytic selection.
