Step 1: Understanding the Question
The question asks to name two specific varieties from each of two distinct categories of rice: high-yielding varieties (HYVs) and Basmati varieties.
Step 2: Detailed Explanation
Two High-Yielding Varieties (HYVs) of Rice:
These varieties were central to the Green Revolution and are known for their high productivity.
IR-8: Often called the "miracle rice," this was one of the first semi-dwarf HYVs developed at the International Rice Research Institute (IRRI). It has very high yield potential but its grain quality is coarse.
Jaya: A popular HYV developed in India, which even out-yielded IR-8. It is also a semi-dwarf, high-yielding variety widely cultivated across the country.
Two Basmati Varieties of Rice:
These varieties are famous for their distinct aroma, long slender grains, and excellent cooking quality.
Basmati-370: A traditional, tall-growing Basmati variety from the Punjab region, known for its exceptional aroma and grain quality, although its yield is low.
Pusa Basmati-1121: A modern, evolved Basmati variety renowned for having the world's longest cooked rice grain. It has excellent aroma and cooking qualities combined with a higher yield than traditional Basmati varieties.
Step 3: Final Answer
High-Yielding Varieties: IR-8, Jaya.
Basmati Varieties: Basmati-370, Pusa Basmati-1121.
