Jaya and Ratna are two rice varieties associated with India's green revolution.

1. Jaya is identified as IET-723. This rice variety matures in approximately 130 days, producing long, bold, white grains with a yield of 50-60 quintals per hectare.
2. Ratna is identified as IET-1411. It matures in about 130-135 days, yielding long, slender, white grains with a productivity of 45-50 quintals per hectare.
3. ‘Himgiri’ is a wheat variety developed through hybridization and selection for resistance to rust pathogens. It is resistant to leaf rust, stripe rust, and hill bunt.
4. Developing crops with enhanced levels of vitamins and minerals to improve human nutrition is called biofortification, which is a practical approach to addressing health issues.
