IR36 is a high-yielding, semi-dwarf rice variety developed in 1976 by Dr. Gurdev Khush at the International Rice Research Institute (IRRI) in the Philippines. It was created by cross-breeding IR8 with 13 parent varieties from six countries, resulting in a cultivar that combined early maturity, disease and pest resistance, and desirable grain quality.vishnuricemill.com+3ISAAA+3Wikipedia+3Wikipdia, l'encyclopdie libre+3vishnuricemill.com+3Pitambar foods+3
Rapid Maturity: IR36 matures in approximately 105 days, significantly faster than traditional varieties that take 150170 days, and quicker than its predecessor IR8, which matures in about 130 days. Wikipdia, l'encyclopdie libre+4vishnuricemill.com+4Pitambar foods+4
High Yield Potential: Under optimal conditions, IR36 can yield up to 4,235 kg/ha, with average yields ranging between 3,5004,000 kg/ha, depending on factors like sowing time and land type. ResearchGate
Pest and Disease Resistance: The variety exhibits strong resistance to several major pests and diseases, including stem borers, bacterial leaf blight, and blast, reducing the need for chemical pesticides. samaytrade.com+7ISAAA+7vishnuricemill.com+7
Grain Quality: IR36 produces medium-long, slender grains that are non-aromatic, making them suitable for a variety of dishes. The grains are preferred in many countries for their cooking quality and texture. Pitambar foods+5Wikipedia+5vishnuricemill.com+5
Adaptability: The variety is well-suited for both rainfed upland and irrigated ecosystems, making it versatile across different agricultural settings. Krishi Rasayan Group
IR36 became one of the most widely planted rice varieties globally during the 1980s, covering approximately 110,000 km. Its rapid adoption contributed significantly to the Green Revolution in Asia by increasing food security and reducing rice prices. The success of IR36 paved the way for the development of subsequent high-yielding varieties like IR64 and IR72.IRRI Books+7Wikipedia+7Pitambar foods+7
In India, IR36 is still cultivated and available through various suppliers. It is commonly offered as parboiled or raw rice in different packaging sizes, catering to both domestic consumption and export markets.
