Q.Name any five hybrid varieties of crop plants which have been developed in India.

Plant breeders in India have developed several hybrid varieties of crop plants by crossing selected parent lines to combine desirable characters such as high yield, disease resistance and adaptability. Well-known examples include:

• Cotton — Hybrid-4 (H4): The world's first cotton hybrid was developed in India (in Gujarat, by Dr. C.T. Patel), combining high fibre yield with other desirable qualities.
• Sugarcane — Co (Coimbatore) hybrid varieties: Developed by hybridising the thick-stemmed but low-sugar, disease-susceptible Saccharum officinarum (tropical sugarcane) with the thin-stemmed but hardy, disease-resistant, higher-tillering Saccharum barberi / Saccharum spontaneum (North Indian canes), to combine high sugar content with adaptability and disease resistance to North Indian growing conditions.
• Maize — hybrid varieties (e.g., Ganga-5): Hybrid maize varieties were bred for higher grain yield compared to traditional open-pollinated varieties.
• Sorghum (jowar) — CSH-1: India's first hybrid variety of sorghum, giving significantly higher yield than the traditional varieties grown earlier. …

Name five well-known Indian hybrids across different crops (cotton, sugarcane, maize, sorghum, bajra), briefly noting what makes each a 'hybrid' …

• Naming disease-resistant varieties (e.g., Himgiri wheat, Pusa Shubhra cauliflower) instead of true hybrids produced by crossing two distinct parent lines — the question specifically asks for hybrids.
• Listing only one crop's hybrids (e.g., several sugarcane varieties) instead of five examples across different crops. …
