Bagging is an important step in artificial hybridization, in which an emasculated flower is covered to avoid pollination by unwanted pollen to get desirable superior varieties.
In artificial hybridization, emasculation is the first step, during which we remove immature anthers or stamens in a bisexual flower to avoid self-pollination.
Bagging follows emasculation to prevent random cross-pollination and desirable pollen is dusted on the stigma of the emasculated flower.
Thus, the bagging technique is essential in a plant breeding program:-
to prevent random cross-pollination or prevent cross-pollination by undesirable pollen.
It also ensures that only desirable pollen is dusted on the receptive stigma to get a commercially superior hybrid variety.
Bagging is the second step in the artificial hybridization technique, where the emasculated flower is covered to prevent unwanted pollination and dusted with pollen collected from desirable varieties to get a superior hybrid variety.
Thus, it prevents random pollination and ensures that a superior hybrid variety is obtained.
