The correct answer is (b), Sonara-64.
Sonara-64 is a high-yielding semi-dwarf wheat variety that was developed in India in the 1960s. It was the first wheat variety to be developed through induced mutation, a process in which a plant’s genetic material is altered using radiation or chemicals. Sonara-64 was a major breakthrough in the Green Revolution, which helped to increase agricultural production in India and other developing countries.
Kalyan Sona is another high-yielding wheat variety that was developed in India in the 1960s. However, it was not developed through induced mutation. Sharbati Sonara is a hybrid wheat variety that was developed in India in the 1980s. It is a cross between Sonara-64 and another wheat variety called Sharbati Sonora. Sonalika is a high-yielding wheat variety that was developed in India in the 1990s. It is not a hybrid variety.
Induced mutation is a process in which a plant’s genetic material is altered using radiation or chemicals. This can be done to create new varieties of plants with desirable traits, such as resistance to pests or diseases. Induced mutation is a powerful tool that has been used to develop many important crops, including wheat.
The Green Revolution was a period of agricultural development that began in the 1940s and 1950s. It was a time of rapid technological and scientific advancement in agriculture, which led to increased crop yields and improved food security. The Green Revolution was a major success, and it helped to lift millions of people out of poverty.
