It was thus difficult to produce hybrid rice in large quantities. In 1961 he spotted a seed-head of wild hybrid rice. [12] By 1964, Yuan hypothesized that naturally-mutated male-sterile rice could exist and could be used for the creation of new hybrid rice varieties. He and a student spent the summer searching for male sterile rice plants.
Hybrid Rice. Hybrid rice is a type of Asian rice that has been crossbred from two very different parent varieties. [1] As with other types of hybrids, hybrid rice typically displays heterosis or "hybrid vigor", so when grown under the same conditions as comparable purebred rice varieties, it can produce up to 30% more yield.

Henry Monroe "Hank" Beachell (September 21, 1906 – December 13, 2006) was an American plant breeder. His research led to the development of hybrid rice cultivars that saved millions of people around the world from starvation.
Yuan Longping of China's National Hybrid Rice Research and Development Center set a world record for rice yield in 1999 at 17.1 metric tons per hectare (7.6 short tons per acre) on a demonstration plot. This employed specially developed hybrid rice and the System of Rice Intensification (SRI), an innovation in rice farming. [38]
Li Bihu (Chinese: 李必湖; pinyin: Lǐ Bìhú; born February 1946) is a Chinese agronomist best known for developing the hybrid rice. He was a student and assistant of Yuan Longping. [1] He is a member of the Chinese Communist Party. He was a delegate to the 11th and 12th National Congress of the Chinese Communist Party.
IR8 is a high-yielding semi-dwarf rice variety developed by the International Rice Research Institute (IRRI) in the early 1960s. It was developed by an IRRI team consisting of Peter Jennings, Hank Beachell, Akira Tanaka, T.T. Chang, S.K. De Datta, and Robert Chandler.
This remarkable improvement was based on three essential crops. First came the development of hybrid maize, then high-yielding and input-responsive "semi-dwarf wheat" (for which the CIMMYT breeder N.E. Borlaug received the Nobel prize for peace in 1970), and third came high-yielding "short statured rice" cultivars. [9]
Pusa Basmati 1121 is an independently derived Basmati rice variety, evolved through the process of hybridization over a long breeding process. This variety of basmati rice was developed by Padma Shri awardee Dr Vijaipal Singh at Indian Agricultural Research Institute (IARI), New Delhi.
