Rice researchers identify genetic lines suitable for ecosystems in Bangladesh

Rice researchers have identified advanced breeding lines adapted to various types of environment that could help develop new lines and varieties that are highly adapted to local ecosystems in Bangladesh to help farmers increase productivity and, therefore, strengthen the country’s food security.

The trial results were presented at the AGGRi Network 2022 Annual Trial Progress Meeting held on May 10 in Dhaka, Bangladesh, a press release said.

The agricultural materials were tested for their short, medium and late maturity and their tolerance to stress (against cold, salinity and submersion or flooding). They have been tested to select the superior breeding lines in different environments in Bangladesh through field trials under the supervision of International Rice Research Institute (IRRI) Bangladesh office and NARes partners .

The results were part of various field tests conducted in Aman in 2021 by IRRI Bangladesh researchers in collaboration with Bangladesh Rice Research Institute (BRRI), Bangladesh Nuclear Agriculture Institute ( BINA) and Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU). The series of experiments were conducted in seven districts including Gazipur, Rajshahi, Rangpur, Kushtia, Cumilla, Satkhira and Barisal. During these tests, the researchers studied various materials in the short, medium and long term and identified whether they are suitable for drought, salinity or if they are tolerant of flooding.

The trial results are valuable to IRRI and NARes partners such as BRRI, BINA, public universities and private entities, as they could help enrich their rice breeding research and development and inform the how they develop new varieties.

Dr. Md Shahjahan Kabir, Director General of BRRI, was present as the chief guest and Dr. Mirza Mofazzal Islam, Director General of BINA, was present as a special guest at the meeting.

The event was chaired by Dr. Humnath Bhandari, IRRI’s representative for Bangladesh. A wide range of participants attended the meeting, including plant breeders and molecular breeders from IRRI Headquarters in Manila and IRRI in Bangladesh; scientists from BRRI and BINA, professors from BSMRAU, Khulna University (KU), Sylhet Agricultural University (SAU) and scientists from five private partner companies such as Aftab Bahumukhi Farms Limited, Ispahani Agro Limited , Lal Teer Seed Limited, Metal Agro Limited, and Supreme Seed Company Limited.

“Taken together, improvements in product focus, selection accuracy, selection intensity, and cycle time, driven by the effective application of new genotyping, phenotyping, and decision aids, have the potential to increase the current rate of genetic gain in staple food crops produced by farmers in the developing world from a current rate that is likely well below 1% per year ( and in many cases not significantly different from zero) to at least 2%,” said Dr. Mirza Mofazzal Islam, Director General of BINA.

“In this process, farmers will be better protected against a rapidly changing climate and better able to adapt to production systems that move quickly to market,” he added.

“We have a lot of challenges in the future to maintain food security; BRRI needs massive reform both in human resource development and in physical facilities. It is expected that the contribution and collaboration of the ‘IRRI will continue to improve the research capacity of BRRI, especially in the field of advanced technologies such as genomics, phenomics, proteomics, bioinformatics, genome editing, rapid selection, automation, digitalization, mechanization and infrastructure development,” said Dr. Md Shahjahan Kabir, Director General of BRRI.

At the end of the program, the main guest and the special guest mentioned that this event was important and timely for rice research in Bangladesh, and they hoped that IRRI would continue its research in Bangladesh to improve our selection of rice. rice and play a key role in the diet. safety in Bangladesh.
