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
