Picking up cross pollinating plants with superior phenotype for further propagation is\tMass selection\tPure line selection\tHybrid vigou\tIntroduction

The correct option is 1.
Pollination is the process by which pollen is transferred from the anther (male part) to the stigma (female part) of the plant, thereby enabling fertilization and reproduction.This takes place in the angiosperms, the flower bearing plants.

In spite of a common perception that pollen grains are gametes, like the sperm cells of animals, this is incorrect; pollination is a phase in the alternation of generations. Each pollen grain is a male haploid gametophyte, adapted to being transported to the female gametophyte, where it can effect fertilization by producing the male gamete (or gametes), in the process of double fertilization).
