how is bagging technique useful in plant breeding programme
Answers
Answer:
Bagging is a technique used to prevent the fertilization of stigma from undesired pollen by covering the emasculated flower with butter-paper. It is useful in a plant breeding programme because only desired pollen grains for pollination and protection of the stigma from contamination of undesired pollen.
Answer:
Bagging technique is used to ensure cross pollination in artificial hybridization of plants.
Anthers are removed before they dehisce from the flower of the female plant if it is bisexual. This step is referred to as emasculation. There is no need to remove the anthers if the flower is unisexual. The flowers are then covered with a bag of suitable size, generally made up of butter paper, to prevent contamination of its stigma with unwanted pollen. This process is called bagging.
Advantages of bagging technique
1. It is necessary for cross-breeding and to prevent pollination by unwanted species in plant breeding.
2. Commercially superior hybrid varieties can be obtained by cross pollination of different useful species.
3. It helps to avoid inbreeding depression caused by self pollination.
