A practical, rapid generation-advancement system for rice breeding using simplified biotron breeding system
A new plant breeding method-the biotron breeding system (BBS)-can rapidly produce advanced generations in rice (Oryza sativa L.) breeding. This method uses a growth chamber (biotron) with CO2 control, accompanied by tiller removal and embryo rescue to decrease the period before seed maturity. However, tiller removal and embryo rescue are laborious and impractical for large populations. We inves...
متن کاملRice Breeding
This chapter deals with breeding aspects of one of the most important crops for food security in the world. Initially it shows how diverse rice is with 22 species, different levels of ploidy and six diversity groups. The choice of parents for crossing, when having such wide genetic diversity available, requires careful characterization and evaluation of the germplasm as well as good knowledge a...
متن کاملPower of conventional rice breeding
With the decreasing trend in rice consumption in Japan, breeding for new types of rice plant, which is a major responsibility of breeders has also become a political issue. The need for restoring Japanese agriculture and maintaining self-sufficiency in rice production has always been tightly linked to economic partnership agreements and trade liberalization. As a result, rice production has bee...
متن کاملThe Use of DNA Markers in Rice Breeding
The development of molecular maps and the complete sequencing of the rice genome have created many opportunities for the application of DNA markers in breeding and genetics. Markerassisted selection (MAS) has become a practical tool in cultivar improvement. MAS is time-saving, very efficient, can promote bio-safety (no need for pathogen or insect pest inoculations during screening trials), reli...
متن کاملBreeding for Iron-dense Rice in Bangladesh
Fifty rice varieties collected under different categories from various sources were grown at the BRRI field during the 2001 transplant aman season ( July–November). Precautions were taken during harvest and processing to prevent mineral contamination. All samples were hand-pounded before being analyzed for iron and zinc content. The iron and zinc content varied considerably within the different...
