Sonalika and Kalyan Sona are high-yielding, semi-dwarf wheat varieties released in India during the Green Revolution.

Sonalika and Kalyan Sona are two of India's landmark high-yielding, semi-dwarf wheat (Triticum aestivum) varieties, developed and released in the mid-to-late 1960s as part of India's Green Revolution. They were bred using semi-dwarfing genes introgressed from Mexican wheat varieties developed under Norman Borlaug's wheat-breeding programme (via CIMMYT). Compared to older tall varieties, these semi-dwarf types:

• lodge (fall over) far less under heavy grain load and fertiliser input,
• respond strongly to irrigation and nitrogenous fertilisers,
• and give a much higher grain yield per hectare. …

Sonalika and Kalyan Sona are high-yielding semi-dwarf wheat varieties central to India's Green Revolution.

Sonalika and Kalyan Sona are among the most celebrated high-yielding varieties (HYVs) of wheat introduced in India during the mid-1960s, at the start of the Green Revolution. These varieties were bred using semi-dwarfing genes (originally from Japanese wheat, incorporated by Norman Borlaug's breeding programme in Mexico), which gave the plants a shorter, sturdier stem that could support a heavier grain head without lodging (falling over), while also responding well to higher doses of fertiliser and irrigation.
