In the process of fertilization, the sperm of the stamen unites with the egg of the female. Because the sperm and egg have different characteristics, there is a possibility of creating a new species. The new variety is different from the parent plant.
Iri-8 rice was developed in the Philippines by crossbreeding Indonesia’s Peta rice and Taiwan’s Dee-gee-woo-gen rice. The yield of this rice is 90-100 maunds per acre.
Erichile rice was developed by breeding Peta rice from Indonesia, TKM-6 rice from India and Taichu-1 rice from Taiwan. The yield of this rice is 70-75 maunds per acre. The yield of Iri-5 rice is 70-75 maunds per acre. High yielding Eri rice is Eri-20, Eri-28, Eri-29 etc.
Bangladesh Rice Research Center developed Birishail rice by crossbreeding BR-20 and BR-3. The four Ufshi rice varieties developed by the Bangladesh Rice Research Center are Chandina (BR-1), Mala (BR-2), Shahi Balam (BR-15) and Shrabni (BR-26).
Bangladesh Agricultural Research Institute (BRRI) has developed 17 Ufshi varieties of wheat through hybridization. High yielding wheat varieties are Balaka, Akbar, Kanchan, Barkat and Saugat. Besides, Ez-27 and Ez-28 wheat are more improved.
Disease-resistant varieties are developed by breeding cultivated disease-causing crops with wild disease-resistant crops. Mukta (BR-11), Ghazi (BR-14), Mohini (BR-15) etc. disease resistant varieties of rice.
Artificial breeding has created varieties of plants that can grow in adverse environments. All these varieties can tolerate drought, flood, salinity etc. due to different characteristics.
The characteristics of grain size, color, smell, taste etc. have been improved through artificial breeding.
Through artificial hybridization it has been possible to reduce the cultivation period of the crop to 20-30 days. This new variety yields before the onset of unfavorable conditions.
