Abstract
“Specialty rices” is a common name for varieties that present uncommon grains with distinctive features as pericarp color, grain shape and size or aroma. Most of these rices are related to cultural traditions and ceremonies, but some have higher nutritionally value than white rice. Considering that today people are searching for foods that could help to improve and maintain health, specialty rices would also be considered in some way as functional food. As a specific market, the economic values of these grains are also higher than those of white rice. So, the new red rice variety SCS119 Rubi and the new black rice variety SCS120 Onix were developed in order to attend the specific and economically important specialty rices market, and should be consumed as a whole rice grain. Experimental tests performed with these varieties showed that they could be recommended to all rice-producing regions of Santa Catarina State, Brazil.
Highlights
The Oryza L. genera belongs to the Poaceae (Gramineae) family and encompasses around 25 species, of whichHow to cite this paper: Wickert, E., et al (2014) Exploring Variability: New Brazilian Varieties SCS119 Rubi and SCS120 Onix for the Specialty Rices Market
Despite the richness of genetic resources, only a small proportion of the world rice germplasm collections have been used in breeding programs
Despite SCS119 Rubi showed a little low productivity when compared to the controls, the red pericarp colour should determine its market value
Summary
How to cite this paper: Wickert, E., et al (2014) Exploring Variability: New Brazilian Varieties SCS119 Rubi and SCS120 Onix for the Specialty Rices Market. 23 are considered wild and only two are cultivated, i.e. O_sativa L. and O. glaberrima Steud [1]. O. sativa species is cultivated worldwide and O. glaberrima only in Africa. On rice the commercial exploitation of a reduced genetic base and the prevalence of a small set of landraces in the breeding process has been the general approach for developing new varieties. If compared with other crop species the genetic diversity in world rice germplasm is quite large. Despite the richness of genetic resources, only a small proportion of the world rice germplasm collections have been used in breeding programs. As a consequence of the high genetic similarity found within several commercial rice germplasms around the world, their phenotypes present high resemblance
