accelerated breeding

Speed breeding is the common name given to the studies to shorten the growing period of a generation from seed to seed by using different methods. Thanks to speed breeding, a generation period can be reduced by 30-50%, although it varies according to the plants. Different applications can be used individually or in combination in speed breeding studies. These applications are given below.

**Photoperiod time:**The photoperiod period applied in standard climate room and greenhouse conditions is 16/8 hours. In speed breeding studies, this period can be applied as 20/4 hours or 22/2 hours. In this way, the exposure time of plants to light is extended and generation is completed in a shorter time.

Early harvest:

 When the seeds are in the soft dough stage, the spikes are taken and left to dry for 3 days in 35°C ovens. In this way, the amount of moisture in the seeds is reduced and the drying of the seed is ensured. Then the spikes are harvested.

Pre-application:

In order to both break the dormancy of the seeds dried in the oven and provide a more uniform emergence, the seeds; It is placed in petri dishes with germination paper. A solution containing 0.5 ppm Gibberellic acid is added to them. Petri dishes are kept in the refrigerator at +4 °C for 3 days.
