A hybrid rice optimization algorithm
2016 11th International Conference on Computer Science & Education (ICCSE), 2016An optimization algorithm called hybrid rice optimization algorithm (HRO) is proposed in the paper which is inspired by the breeding process of three line hybrid rice. The three line are sterile line, maintainer line, restorer line. The sterile line is hybridized with the maintainer line to produce the hybrid rice.

Hybrid rice and Green Super Rice
Chinese Science Bulletin, 2016Rice is the most important staple food that feeds more than half of the world’s population, particularly in Asia where 90% of rice is consumed. Increasing rice production is essential to meet the demands of a growing human population, with its rising living standards.

Hybrid rice is a type of Asian rice that has been crossbred from two very different parent varieties. As with other types of hybrids, hybrid rice typically displays heterosis or "hybrid vigor", it can signficantly outyield other rice varieties, so when grown under the same conditions as comparable purebred rice varieties, it can produce up to 30% more ...

One hundred and thirtysix hybrids were developed utilizing four cytoplasmic genetic male sterile lines (V 20A, Zhen Shan 97A, IR 46829A and IR 46830A) and 34 effective restorers. Heterosis, heterobeltiosis and standard heterosis were found to be significant for grain yield and other yield attributing characters in most of the hybrids. The heterosis for

A historical review of hybrid rice breeding
Journal of Integrative Plant BiologyABSTRACTThe development of germplasm resources and advances in breeding methods have led to steady increases in yield and quality of rice (Oryza sativa L.). Three milestones in the recent history of rice breeding have contributed to these increases: dwarf rice breeding, hybrid rice breeding, and super rice breeding.

Molecular mechanisms of hybrid sterility in rice
Science China Life Sciences, 2019Hybrid sterility presents a major bottleneck in hybrid crop breeding and causes postzygotic reproductive isolation in speciation. Here, we summarize the current understanding of the genetics of rice hybrid sterility and highlight new advances in deciphering the molecular basis of the major genetic loci for hybrid sterility in rice.

Thiry six hybrids were developed utilising three cytoplasmic genetic male sterile lines (V 20 A, IR 58055 A and IR 62829 A) and twelve testers and they were studied for the extent of heterosis on six quantitative characters viz., days to flowering, panicles per plant, grains per panicle, spikelet fertility.

TNAU Rice Hybrid CO4 – A New Fine Grain Rice Hybrid
Madras Agricultural Journal, 2013TNAU Rice Hybrid CO 4 (TNRH 174) a derivative of the cross TNAU CMS 23 A/ CB 174 R, released during the year 2011 matures in 130-135. The hybrid recorded a mean productivity of 7327 Kg/ha with 14.5 and 11.3 per cent increase over CO (R) 49, the fine rice check variety and 27P11, the private hybrid respectively.
