Scientists are trying to transfer apomictic genes into hybrid varieties of several of our food and vegetable crops so that:

1. They get resistance against common pathogens

2. The yield of these plants can be increased many folds

3. Hybrid seeds need not be produced every year

4. Their germplasm is easily stored in labs for further research

Seeds offer several advantages to angiosperms. Seed formation is more dependable because:

1. Seeds have better adaptive strategies for dispersal

2. Reproductive processes become independent of water

3. Hard seed coat provides protection to the young embryos

4. They generate new genetic combinations leading to variations
