Hybrid Rice

Hybrid rice is grown from hybrid rice seed which is produced by growing an inbred rice variety having sterile pollen which is cross pollinated with normal pollen from adjacent rice plants of a different inbred variety. Hybrid rice therefore has two genetically different parents. As with other types of hybrids, hybrid rice typically displays heterosis (or hybrid vigor) such that when it is grown under the same conditions as comparable high-yielding inbred rice varieties it can produce up to 30% more rice. High-yield crops, like hybrid rice, are one of the most important tools for combating world food crises. The first hybrid rice varieties were released in China
