Which of the following statement is correct regarding the improved varieties of crop?

Options

A. In 1963 Several varieties such as sonoro-64 and lerma rojo-64, which were high yielding and disease resistant, were introduced all over the rice growing belt of India.
B. Sharbati sonora is a important variety of wheat produced by gamma rays treatment of sonora-64
C. Pomato is somatic hybrid between potato and brinjal.
D. Parbhani kranti, resistance to yellow mosaic virus is produced by mutation breeding.

Answer

To determine which statement is correct regarding the improved varieties of crops, we can analyze the options provided based on the information given in the video transcript.

### Step-by-Step Solution:

1. **Identify the Varieties Introduced**: The video mentions that in 1963, several high-yielding and disease-resistant wheat varieties were introduced in India, such as Sonora 64 and Larma Rojo 64. This indicates that improved varieties were developed for specific crops, particularly wheat.

**Hint**: Look for historical context about crop improvement in the transcript.

2. **Evaluate the First Statement**: The first statement regarding Sharbati Sonara being produced by gamma rays is incorrect. The transcript clarifies that Sharbati Sonara was produced through hybridization, not mutation breeding.

**Hint**: Check if the method of production mentioned aligns with what is stated in the transcript.

3. **Evaluate the Second Statement**: The second statement claims that Pomato is a hybrid between Potato and Brinjal. The transcript corrects this by stating that Pomato is actually a hybrid between Potato and Tomato, while the hybrid between Potato and Brinjal is called Bomato. Thus, this statement is also incorrect.

**Hint**: Pay attention to the names of hybrids and their correct pairings as mentioned in the transcript.

4. **Evaluate the Third Statement**: The fourth statement mentions Prabhanikranti, a variety of Bhindi (Okra), which is resistant to the yellow mosaic virus and produced by mutation breeding. The transcript confirms that this statement is correct as it describes mutation breeding involving the use of mutagens.

**Hint**: Look for specific examples of crops and their breeding methods to identify the correct statement.

5. **Conclusion**: After evaluating all the statements, the only correct statement is the one about Prabhanikranti being a variety of Bhindi that is resistant to yellow mosaic virus and produced by mutation breeding.

### Final Answer:
The correct statement regarding the improved varieties of crops is: "Prabhanikranti is a variety of Bhindi, resistant to yellow mosaic virus and produced by mutation breeding."
