Honestly the rice varieties in India should be promoted and protected more. The diversity and health benefits of these varieties is immense.
These genotypes are being lost to industrial mono-cropping. The government is doing nothing about it.
This is happening worldwide and is one of the tragedies of modernity. Mexico for instance has tons of regional varieties of peppers that don't grow anywhere else except for in a very specific micro climate and they're disappearing in large part because of cheap imports that makes farming them unprofitable.
