Hybrid rice in Bangladesh

In 2003, nearly 200 tons of hybrid rice seeds were reported to be sold in the country by the Bangladesh Agricultural Development Council (BADC) and Bangladesh Rural Advancement Committee (BRAC), the two main agencies involved in hybrid rice seed production. This seed volume was reported to be cultivated on at least 10,000 ha within the year.

Experimental hybrid performance
Conditions during the transplanted aman season (July-December) of 2003 in Bangladesh were harsh on account of very heavy rains and floods. In an effort to select and identify superior hybrids for such an environment, two promising hybrids were evaluated in 10 farmers’ fields in Thakurgaon, Rangpur, Jessore, Masura, Khulna, Sakhira, and Gazipur. Hybrids BRRI 1A/BR 827R and BRRI 1A/BR 168R outyielded check variety BRRI Dhan 39 by 1 t/ha.
 

BRRI Hybrid Dhan-1, the first public-sector hybrid in Bangladesh, which yielded nearly 1.2 t/ha (20%) higher than the highest-yielding inbred (BRRI-29) in selected districts during the boro season, did not show superiority in the wet (aman) season.
 

Newer experimental hybrids continue to be evaluated in the country. The yield advantage of these new hybrids ranges from 0.5 to 1 t/ha over that of the high-yielding check varieties (BRRI Dhan 31 and BRRI Dhan 39) for the aman season.
 

Seed production
The Bangladesh Rice Research Institute (BRRI) maintains the genetic purity of the parental lines of BRRI Dhan-1 through a nucleus seed production program. This effort has resulted in 30 kg of seed of the male parent BR 827R and 1.5 kg of purified seed of the female parent IR58025A. These nucleus seeds will be used in the future production of breeder seeds.
 

Five areas have been reported to be suitable for hybrid rice seed production in the Jessore and Barisal regions after 11 CMS seed production plots were established at different sites within these regions. These plots were set up to expose potential farmer seed growers to this technology and to assess the possibility of commercial-scale hybrid rice seed production in the area.
