F1 Hybrid Seeds What are They?

What are F1 Hybrid Seeds?F1 hybrid Seeds, In botanical terms seeds are the mature and fertilised ovule that contains the embryo of the plant in dormant condition and which can grow into an adult plant when the conditions are favourable.

Hybrid Seed

When two parent plants are crossed, it will produce seeds which will contain the genetic qualities of both the parent plants. These seeds when germinated from the first filial generation or F1 generation. The seeds produced by F1 generation are called F1 seeds. You can select plants with desirable qualities such as better yield, disease resistance to cross breed so that the F1 seeds have superior quality.

  • Plants produced from F1 hybrid seeds are stronger and have better survival features than the plants produced from parent plants with identical genes.
  • Creating F1 seeds are expensive, but they can produce higher yields and are more resistant to diseases.

If you are trying to breed plants you should know about the difference between open-pollinated, self-pollinated and hybrid plants.

Open–Pollinated

Plants in which pollination is done by insects, wind or by a gardener is called open –pollinated plants. The plant will produce fruits and seeds after pollination. Some open pollinated plants will have male and female flowers on a single plant and the pollination is the movement of pollen from anther of the male flower to the stigma of the female flowers. The seeds resulted from this type of pollination will produce plants that have all the same qualities of the parent plant.

Self-Pollinated

When the pollen from the anther of the flower falls on the stigma of the same flower it is called self-pollination. Natural actions like a flower opening or just the shaking of the flower in the wind can transfer the pollen to the stigma. You will be able to collect the seeds of these self-pollinated plants to produce the same variety of plants in the next growing season. A plant which is open pollinated or self pollinated for about 50 years are known as heirloom plants.

Hybridisation

When the plants grown for commercial purpose requires some special attribute like increased flowering, increased fruit formation, size, colour or taste the hybridisation is considered. To do hybridisation, pollen from one plant with desirable character is transferred to the pistil of the flower of another plant with another desirable character by artificial methods. The fruits formed after cross-pollination will produce seeds which can produce plants. They will have the qualities of both the parent plants. Some of these plants may have the required characteristics and some may not have the preferred features. If the plants produced by cross pollinated seeds have the desired qualities, the cross will be repeated to create and use the new varieties or the hybrids.

You should not confuse hybrids with genetically modified plants as there are no molecular genetics methods used in creating the hybrid plants. There is no artificial modification of genes happening in hybrid plants. Only the genetic materials of two different varieties of the plant will only get mixed up in different combinations in hybrids.
