Phenotypic changes during 100-year rice breeding programs in Hokkaido
Plant breeding programs in local regions may have genetic and phenotypic variations that are desirable and shape adaptability during the establishment of local populations. Despite the characterization of genetic population structures in various kinds of populations, the effects of variations in phenotype on agro-economical traits currently remain unclear. In the present study, we evaluated phe...
متن کاملMarker-assisted introgression in backcross breeding programs.
The efficiency of marker-assisted introgression in backcross populations derived from inbred lines was investigated by simulation. Background genotypes were simulated assuming that a genetic model of many genes of small effects in coupling phase explains the observed breed difference and variance in backcross populations. Markers were efficient in introgression backcross programs for simultaneo...
متن کاملRice Variety Improvement Using Marker-Assisted Selection
Molecular marker-assisted selection (MAS) is currently being employed in two areas of rice breeding at the University of Arkansas Rice Research and Extension Center (RREC) in Stuttgart. Presently the objective of the program is to accelerate the development of rice cultivars with improved cooking quality and rice blast disease resistance using two well-characterized molecular markers. A co-domi...
متن کاملThe challenges in Marker Assisted Breeding
This paper describes our opinion on the future of Marker Assisted Breeding. Concomitantly, it provides a comprehensive overview of the different types of application in Marker Assisted Breeding.
متن کاملIon-beam irradiation, gene identification, and marker-assisted breeding in the development of low-cadmium rice.
Rice (Oryza sativa L.) grain is a major dietary source of cadmium (Cd), which is toxic to humans, but no practical technique exists to substantially reduce Cd contamination. Carbon ion-beam irradiation produced three rice mutants with <0.05 mg Cd⋅kg(-1) in the grain compared with a mean of 1.73 mg Cd⋅kg(-1) in the parent, Koshihikari. We identified the gene responsible for reduced Cd uptake and...
