Increasing Rice Yield through Targeting Genetic Potentials by Rice Types

Bangladesh needs an average rough rice yield of 9.11 t ha-1 by 2050 which can not be achieved equally across all the geographic regions since the country has various ‘rice types’ with varying yield potentials. This paper focuses on strategic innovations for reaching the yield target by refining rice types. Based on rice ecosystems and the pressing needs, we divided rice areas of Bangladesh in 17 different types. We estimated year-wise land areas and allocated achievable yield targets for each of the rice types. Finally, we compared the target yields and the yields of top-yielding rice varieties in Bangladesh by 2020 across the rice types to understand the current status of our varietal improvement programmes. We sorted out how much…
