Hybrid rice is a type of rice that has been bred from two very different parents. It can significantly outyield other rice varieties. IRRI is working with its partners to develop new and improved hybrid rice varieties.
Hybrid rice is the commercial rice crop grown from F1 seeds of a cross between two genetically dissimilar parents with superior quality.
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.

Hybrid rice is one of the feasible and readily adoptable technologies to increase rice productivity (Mahalingam, 2013). In the Philippines, hybrid rice yields 15-20% more than the inbred check.
Evidently, most rice farmers are still not convinced of the economic superiority of hybrid rice to be willing to pay the full cost of hybrid seed production and distribution such that a hybrid rice seed industry can be commercially viable.
A hybrid is the product of a cross between two genetically distinct rice parents. When the right parents are selected, the hybrid will have both greater vigor and yield than either of the parents.
WHEREAS, the report of the performance of hybrid rice indicated a clear yield advantage over the certified inbred seed varieties with farmers getting yield advantage of up to 5 tons per hectare (hybrid yield of up to 12 t/ha) and provinces having average yields of up to 7 tons per hectare.
Dec 13, 2021 · Commercialization of two-line hybrid rice demonstrates the expertise of Chinese hybrid rice experts, led by Professor Yuan, and ensures China standing at the forefront of global hybrid rice development.
Sep 10, 2018 · Replacing half of the rice-growing areas in the world with hybrid rice varieties with a 2 t/ha yield advantage could feed 400‒500 million more people each year. Rice is the main food crop that feeds more than half of the world’s population.
Hybrid rice is produced when the egg is fertilized by pollen from anthers of a rice plant from a different variety or line. In order to produce great quantities of hybrid seeds, two kinds of parental lines are needed, a seed parent which is usually male sterile and a pollen parent.
