Advantages of Cross Pollination
1. Cross pollination brings about genetic recommendation and production of new varieties.
2.Cross Pollination results in healthy and stronger offspring due to phenomenon of hybrid vigour.
3. Several crop plants give significantly higher yields if bees are available and cross pollination is allowed to occur.
4.Variation caused due to cross pollination may results in production of disease resistant plants.
5. Cross pollination results in the production of seeds in self -sterile plants.
Disadvantages of Cross Pollination
1. Cross pollination is not economical. The plants waste lot of energy and food materials in unnecessary adaptations and devices to bring pollination.
2. Cross pollination is uncertain because a factor of chance is always involved.
3. It involves addition of some undesirable character or loss of some important character.
4.Many of the seeds or pollen grains become damaged due to the incomplete process or by spoilage of seeds or pollen grains.
