Identify from the following a pair of better yielding semi dwarf varieties of rice developed in India.
- Kalyan Sona and Sonalika
- Jaya and Ratna
- Sonalika and Ratna
- Jaya and Kalyan Sona
The Correct Option is B
Approach Solution - 1
- Jaya and Ratna are high-yielding, semi-dwarf varieties of rice developed in India.
- These varieties were bred for better yield, shorter plant height, and resistance to lodging.
- They are suitable for high-density planting and are recognized for their improved productivity.
The correct answer is (B) : Jaya and Ratna.
Approach Solution -2
Identify from the following a pair of better yielding semi dwarf varieties of rice developed in India.
The correct answer is: (B) Jaya and Ratna.
In India, the development of semi-dwarf varieties of rice has been a significant achievement to increase rice production. These varieties are characterized by shorter stature, which helps in reducing the lodging of plants during heavy rains, and their higher yield potential due to better utilization of resources like water and nutrients.
Jaya and Ratna are two such varieties of rice developed in India. Both varieties are known for their high yield potential and semi-dwarf nature, which makes them more resistant to diseases and pests, leading to improved productivity in comparison to taller traditional varieties.
These varieties were developed under India's rice improvement programs and have been instrumental in increasing the productivity of rice in various regions of the country.
