Which was first Indian dwarf, amber grained variety of wheat made from sonora-64 y-rays?

1. Sonalika
2. Sharbati sonora
3. Kalyan sona
4. HUW-468

The correct option is 2.
A scientific paper in which Swaminathan and his team claimed to have produced a mutant breed of wheat by gamma irradiation of a Mexican variety (Sonora 64) resulting in Sharbati Sonora, claimed to have a very high lysine content led to a major controversy. The case was discussed as a classic example of scientific misdemeanor and was claimed to be an error made by the laboratory assistant. The episode was also compounded by the suicide of an agricultural scientist.
