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. [2]
Rice can come in many shapes, colours and sizes. This is a list of rice cultivars, also known as rice varieties.There are several species of grain called rice. [1] Asian rice (Oryza sativa) is most widely known and most widely grown, with two major subspecies (indica and japonica) and over 40,000 varieties. [2]
By cross-breeding together IR8 with 13 parent varieties from six nations, Dr. Khush developed IR36, a semi-dwarf variety that proved highly resistant to a number of the major insect pests and diseases that raised farmers' rice yields and drove down prices of the staple food for Asian families. [1]
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.

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.
Other healthy types of rice. Two other varieties of rice are worth mentioning in the healthiest category. First, black rice — also known as forbidden rice — is a whole grain rice with Chinese ...
Ambemohar is low-yielding compared to other varieties of rice, primarily because it is susceptible to diseases. The hybrid called Indrayani with ambemohar parentage was released in 1987. [6] It was developed by Rice Research Centre near Lonavala. [7] Indrayani has also been modified to form new varieties of rice such as Phule Maval and Phule ...
