Answer: increase resistance to fertilizer
Explanation:
A hybrid plant is produced by the selective breeding process. In this process the two parent plants of desired qualities are cross breed so as to obtain the offspring plants or seeds from them which could produce good yield of the crops, which taste best, are resistant to the activity or infestation of the disease causing pathogens.
Fertilizers are added up in the soil so as to improve it's quality in terms of availability of essential minerals which supports growth of the plants. Plants readily absorb these minerals from the soil through the roots. If the hybrid plants are created in such a way that they resist the fertilizers then they will not be capable of absorbing the minerals present in these fertilizers from the soil. This will restrict the growth of the hybrid plants.
On the basis of the above description, increase resistance to fertilizer is not a reason for creating hybrid plants.
