Rice varieties released by BINA are benefiting Farmers in the coastal regions

Rice varieties released by BINA are benefiting Farmers in the coastal regions

Since its establishment in 1961, BINA (Bangladesh Institute of Nuclear Agriculture) BINA already developed and released 56 mutant varieties of different crops. Although initially its mandate was to develop varieties using nuclear techniques only (using radiation to generate mutants), now the scope of their objective has been widened to include both conventional and molecular breeding techniques for crop improvement. Fairly recently their major thrust has been to develop rice varieties in collaboration with IRRI suitable for saline soil in the coastal regions. In 2010, BINA released a salt tolerant rice variety Binadhan-8 by evaluating IRRI breeding lines. Binadhan-8 has been derived from  a Recombinant Inbred Line (RIL) line (FL449, IR66946-3R-149-1-1). The initial  work in which  IR29 and PokkaliB  were used as crossing material were carried out in IRRI.

Binadhan-8 is now cultivated in salt affected areas of Satkhira, Khulna and Chittagong districts and is getting popular due to its tolerance and better yield competing with another high yielding salt tolerant variety, nmaely BRRI dhan47 released by BRRI in 2007. The latter was also an IRRI breeding line of Pokkali origin. Farmers in the coastal salt affected areas can grow both of these rice varieties in the ‘shrimp-ghers’   in boro season by using the water trapped in ghers and growing  a substantial amount of rice there during the  shrimp off-season from September to February.
