Own maize seed can only be produced from varieties which are not hybrids. Hybrid varieties are made by planting two varieties in the same field, allowing I only the male parent to produce pollen, and harvesting the seed only from the female parent. This is controlled crossing of two different parents. The offspring (the hybrid) will perform better than the average of the parents or even better than each of the parents.
