Success of Bt Brinjal in Bangladesh

  1. 1. Md. Rafiqul Islam Mondal Ph. D Former Director General Bangladesh Agricultural Research Institute Success Story on Bt. brinjal in Bangladesh
  2. 2. Bangladesh is one of the most densely populated countries of the world. Around 70% of the people in Bangladesh are directly or indirectly involved in agricultural sector.  Over the last four decades, cereal production has been increased from 10 million tons in 1972 to 39.68 million tons in 2016.  The contribution of agricultural sector in GDP is 14.77%, employs 47% of the total labor forces, cropping intensity approaching to 200%, average farm size is about 0.68 acre Introduction
  3. 3. Introduction common vegetables in Bangladesh  There are about 100 types of local and exotic vegetables are grown in bangladesh  Vegetable is very important for nutritional, financial, and also for food security in Bangladesh. Area: 0.4 m ha, Production : 3.73 m MT (BBS 2015) Present consumption : 62 g/day/person (BBS, 2017), : 125 g/day/person (FAO Stat. 2012) Recommendation : 220g/day/person Production need to be increased more than 3 folds.
  4. 4. Area and Production Trend of Vegetables in Bangladesh over the years
  5. 5. Brinjal as vegetable crop in Bangladesh Brinjal is a good source of minerals and vitamins, rich in total water soluble free reducing sugars, amide proteins among other nutrients as well as high amount of anti oxidant Brinjal Fruits are consumed as cooked vegetables Dried Shoots are used as fuel

  7. 7. Agricultural Biotechnology in Bangladesh Biotechnology is the application of any technology to biological systems and living organisms to develop useful products for specific use. Biotechnological application Tissue culture Embryo grafting Somaclonal variation Micro- propagation Transgenic plant development and production of high yielding and pest/insect resistant varieties through genetic engineering, and biochemical study programmes of some key crop plants have also been initiated in a number of laboratories at Research institutes and Universities.
  8. 8. Agricultural Biotechnology in Bangladesh Bt. brinjal Shoot and Fruit Borer (Bacillus thuringiensis ) LBR Potato Late blight (Phytophthora infestans ) Golden Rice GR-1 (From Daffodil) & GR-2 (From Corn) Salt tolerant rice BRRI dhan 28, 29, 36 and 2 BRRI dhan 47 containing Pea DNA Helicase 45 (PDH45) Bt. Cotton Resistant to Bollworm and Spodoptera/Army worm Jute Genome sequence Bt. Chickpea pod borer Other crops virus resistant tomato and salt tolerant wheat , zinc (Zn) and iron (Fe) enriched transgenic rice variety, antioxidant-enriched black rice variety, a peanut resistant to fungal disease ,
  9. 9. Conceptualization of Agricultural Bio-Technological Support Project -II MOU signed on 27 June 2004 BARC Cornell University, USA Objectives Delivering bio-engineered products and technologies to targeted countries, including Bangladesh. Provided research support in the Bio- technological area, higher training and study visit for Bangladeshi Scientists. Technology access ABSP-II project support
  10. 10. Inception and generation advancement of Bt. brinjal Genotypes at BARI BARI created a multidisciplinary research team under ABSP-II programme and different events are : 2005 : Hybridization of 9 Bangladeshi brinjal cultivars with Bt. brinjal candidate variety at Mahyco and F1 seeds were collected and back crossing programe was initiated (BC1) at Mahyco, India. 2006 : BC2 done at BARI, Bangladesh. 2007 : BC3 done at BARI, Bangladesh 2008 : BC3 (F2) done at BARI, Bangladesh 2009 : BC3 (F3) and BC4 done at BARI, Bangladesh 2010 : BC3 (F4), BC5 done at BARI, Bangladesh. Next season muti- location confined field trial at seven locations 2011 : BC3 (F5) done at BARI, Bangladesh. 9 varieties underwent MLT in 7 locations 2012 : MLT repeated in 7 locations. 2013 : MLTs were repeated in the same 7 locations

  23. 23. Socio-Economic Performance of Bt. brinjal A socio-economic study was conducted in 35 districts of Bangladesh during 2016-17 (Rashid et al., 2018)  Bt, farmers received 13% higher yield compared to non-Bt. farmers  Bt. farmers also received significantly higher gross return (21%) and net income (83%) compared to non-Bt. farmer  The total variable cost and fixed cost were also lower for Bt. farmers compared to non-Bt. farmers
  24. 24. Conclusion and Recommendations .  Increase the no. of Bt. farmers from 20 in 2014 to 7500 in 2018 Farmers understand that Bt. brinjal is profitable because there was no infestation of shoot and fruit borer insect. Farmers can keep their own seeds for next season because varieties are not hybrid.  Less use of insecticides. Finally, cost of production will be reduced, brinjal cultivation will be profitable and farmers will be benefitted. From the experience of Bt. brinjal in Bangladesh, it can be suggested that the biotechnological tools can be successfully utilized in solving many biotic and abiotic problems of crop production The international development partners should come forward to support this type of research initiatives in the developing countries in the World.
