Plant Breeding Division
The major achievements of Plant Breeders of BRRI are the development of high-yielding modern varieties (MVs) of rice both for favorable and unfavorable ecosystem. BRRI has so far released 102 MVs (95 inbred and 7 hybrids):
Plant Breeders have given successful efforts to develop modern varieties for stress ecosystem like salinity, submergence and drought. They have developed BRRI dhan47, BRRI dhan61 and BRRI dhan67 for boro season which could tolerate 12-14 dS/m salinity at seedling stage and also withstand 6-8 dS/m salinity during whole life cycle. Nonetheless, BR23, BRRI dhan40, BRRI dhan41, BRRI dhan53, BRRI dhan54 and BRRI dhan73 are the salinity tolerant varieties for T. Aman with 8 dS/m salinity tolerance at reproductive stage. Three submergence tolerant varieties BRRI dhan51, BRRI dhan52 and BRRI dhan79 have been developed that can survive two to three weeks of submergence. Whereas, four varieties viz. BRRI dhan56, BRRI dhan57, BRRI dhan66 and BRRI dhan71 have been developed which are suitable for drought-prone areas of Bangladesh. In addition, five Zinc (Zn) enriched varieties BRRI dhan62 (short duration) and BRRI dhan72 (medium duration) for T. Aman and BRRI dhan64, BRRI dhan74 and BRRI dhan84 for boro have been developed and released. Emphasis is given to address the research on stress breeding enhancing productivity of rice varieties suitable for stress-prone environment. Additionally, BRRI dhan50 popularly known as Banglamati (Basmati type), BRRI dhan63 (slender balam type) and BRRI dhan81 (slender premium quality and zira type) are the high yielding Boro rice varieties for favourable ecosystem. Plant Breeders also initiated Marker-Assisted Breeding Programme to introduce stress tolerance genes including disease resistance into modern varieties with high yield potential. Of late, BRRI has released two long slender type aromatic rice varieties viz. BRRI dhan70 and BRRI dhan80 with yield potential 5.0 t/ha. BRRI dhan75 is green super T. Aman rice with 115 days growth duration and 5.5 t/ha average grain yield. The cooked rice of BRRI dhan75 has mild aroma and this variety is particularly suitable for the potato growing areas of Bangladesh.
The MVs developed in the 1980s and 2000s are suitable for varying ecosystems and have a wide range of disease and insect resistance, for example, BR17, BR18 and BR19 have been developed for the Boro areas (depressed basins) in the north-eastern region of Bangladesh; BR20, BR21, BR24, BRRI dhan42, BRRI dhan43, BRRI dhan65 and BRRI dhan83 for the upland situation in Aus season (direct-seeded Aus), BR22, BR23 and BRRI dhan46 with photoperiod sensitivity for late transplanting in Aman Season after the recession of the flood water, BRRI dhan27 for the non-saline tidal areas in Aus, BRRI dhan44, BRRI dhan76 and BRRI dhan77 in tidal non-saline areas for T. Aman season and BRRI dhan30, BRRI dhan31 and BRRI dhan32 for rainfed lowland areas. BRRI developed BRRI dhan48, a popular high yielding T. Aus variety and BRRI dhan49, a popular T. Aman variety with nizersail type grain quality and one week earliness than BR11. Plant Breeding Division of BRRI and BRRI Regional Station, Comilla have developed two transplanted Aus rice varieties viz. BRRI dhan82 and BRRI dhan85, respectively. BRRI dhan82 has been released for whole country with 5.5 t/ha yield potential and 100-105 days growth duration. Whereas, BRRI dhan85 has been developed as moderately water stagnation tolerant T. Aus variety with 5.5 t/ha yield potential. Plant Breeding Division, BRRI developed a number of high yielding Boro varieties BRRI dhan58, BRRI dhan59, BRRI dhan60, BRRI dhan68, BRRI dhan69, BRRI dhan81 and BRRI dhan88. BRRI dhan58 is the first variety developed through tissue culture process from BRRI dhan29. BRRI dhan58 is one week earlier than BRRI dhan29 with same yield potential of BRRI dhan29 and hopefully BRRI dhan58 will be the replacement of BRRI dhan29. On the other hand, BRRI dhan59, BRRI dhan60 and BRRI dhan68 have in-between growth duration compared to BRRI dhan28 and BRRI dhan29. Importantly, BRRI dhan60 has extra-long slender grain in size. BRRI dhan88 with medium slender grain, 140-143 days growth duration has been developed for Boro season with 7.0 t/ha average grain yield.
Biotechnology Division of BRRI has developed two Boro varieties viz. BRRI dhan86 and BRRI dhan89 and one T. Aman variety BRRI dhan87. BRRI dhan89 can produce half ton more grain yield than BRRI dhan29 with 3-5 days earlier growth duration and BRRI dhan87 has about 127 days growth duration in T.Aman season but this variety can produce 6.5 t/ha grain yield. BRRI dhan87 will hopefully be able to replace BR11.
Biotechnology Division is one of the major components of rice varietal development program area in BRRI. Since its inception, the division has been working for generating rice breeding lines through different biotechnological tools. Its major thrust includes the varietal development activities for high yield, quality, stress tolerance and biofortification of rice. Currently, it is mainly involved in rice tissue culture, genetic transformation, marker assisted selection (MAS), gene pyramiding, QTL identification and DNA finger printing of the modern rice varieties, advanced breeding lines and local land races.
Genetic Resources and seed (GRS) Division is a vital component of rice varietal development program area in BRRI. The mandate of the Division is rice variety development, germplasm conservation & management and seed technology research. As this division maintain the germplasm conservation which is the key component of any research program. This division also play vital role to earn the maximum number in APA through Breeder Seed Production and distribution. The major achievement of this division is as follows:
1. Developed an aromatic rice variety (BRRI dhan 34 from Khaskani), which is very popular throughout the country
2. Long term genebank (2000 CFT volume) was established in 2007 with a storage facility of 22,000 germplasm for a duration of 50- 100 years
3. A total of 8604 landraces of rice were collected and conserved as long, medium and short term storage.
