The objective of this study was to identify the most popular improved rice varieties which could be targeted for breeding micronutrients including iron, zinc and vitamins that ultimately could help addressing micro- nutrient deficiency induced malnutrition in the poverty stricken regions of South Asia suffering from â€œHidden Hungerâ€.
The purpose of this statistical report is to keep a record of rice varieties for the future use. A repeat survey using the same methodology at a later date would be able to use this benchmark data to assess further erosion of rice biodiversity, the time of pattern of acceptance and drop-out of further improved varieties, regions lagging behind in terms of improved varieties, the changes in use of irrigation and fertilizer, the pattern of seed replacement, etc. The unpublished primary data were further analyzed at RED, BRAC for preparing this statistical report
