Development of high yielding rice

In the 1960s, scientists from the International Rice Research Institute (IRRI) in the Philippines developed Iri rice. IRRI-8 rice was developed by crossing Peta rice from Indonesia and Dee-gee-woo-gen rice from Taiwan. 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 Tichu-1 rice from Taiwan. The yield of this rice is 70-75 maunds per acre. The yield of IRRI-5 rice is 70-75 maunds per acre. High yielding Eri rice is Eri-20, Eri-28, Eri-29 etc.

Bangladesh Rice Research Institute (BRRI) has developed high yielding Biri rice. Birishail was developed by hybridizing BR-20 and BR-3. The four Ufshi varieties developed by the Bangladesh Rice Research Center are Chandina (BR-1), Mala (BR-2), Shahi Balam (BR-15) and Shrabani (BR-26). Earlier varieties cultivated in Bangladesh had a yield of 30-35 maunds per acre. Currently cultivated high yielding varieties yield 70-90 maunds per unit. BR-28 and BR-29 are more advanced varieties. Rice production in Asia has increased at least 4-fold in the last 40 years.

BRRI-28 and BRRI-29 are the most popular rice varieties for farmers in Boro season. At present these two breeds have reduced immunity and are easily affected by blast disease. BRRI-68, 81, 86, 88, 96, 101, 105 and Bangabandhu 100 are being cultivated as alternatives to BRRI-28. BRRI-89, 92, 97, 99, 102, Bangabandhu 100, BINA-25 and BINA-10 in saline areas are being cultivated as alternatives to BRRI-29.
