Class 12 Biology - Chapter Sexual Reproduction in Flowering Plants NCERT Solutions | What is bagging technique? How is it use
What is bagging technique? How is it useful in a plant breeding programme?
Various artificial hybridization techniques (under various crop improvement programmes) involve the removal of the anther from bisexual flowers without affecting the female reproductive part (pistil) through the process of emasculation. Then, these emasculated flowers are wrapped in bags to prevent pollination by unwanted pollen grains. This process is called bagging.
This technique is an important part of the plant breeding programme as it ensures that pollen grains of only desirable plants are used for fertilization of the stigma to develop the desired plant variety.
