Hybrids Of Rice

Hybrid rice is rice that has been created by crossing two different parental strains. Such crosses generally result in an F1 generation that is more robust than either of the parental strains. The improved qualities of the F1 generation is referred to as "hybrid vigour" or "heterosis". The hybrid vigour may result in superior agronomic qualities such as higher yield, stronger resistance to diseases, more efficient use of soil nutrients, and better weed control. Hybrid vigour and other superior qualities arising from crossing genetically different plants have been well known and used by traditional crop breeders for decades.In the past, the production of hybrid rice strains was limited by rice's inherent propensity to self-pollinate. In 1974, Chinese scientists overcame this when they developed the first generation of hybrid rice using a three-line hybrid system based on cytoplasmic male sterile (CMS) lines and hybrid combinations. In 1996, an even more efficient second generation of hybrid rice was developed based on photoperiod-sensitive genetic male sterility (PGMS) lines. Journal impact factor is an index or a criteria devised by Eugene Garfield to categorize journals based on their citations. Impact factor is considered as a putative marker to indicate the journal quality. But the recent policies being adopted to improve the impact factor is becoming a topic of controversies today. This current scenario questions the reliability of impact factor. The citation index cannot be considered to determine the scientific quality of an article because the technicalities are not considering the scientific quality. Knowing or reading an article is not enough to determine their quality validating the content and approving the findings and revalidating the facts is vital in scientific research. It is highly impossible to do a scholar check in each and every article to detect fraudulent or unsubstantial citations.
