Other claims from this paper (13)
- Method / resource A set of 64 chromosome segment substitution lines of O. glaberrima segments in an O. sativa background was built.
- Observation The average size of substituted chromosomal segments was about 10 cM.
- Observation The substitution lines covered the whole donor genome, except small regions on chromosomes 2 and 4.
- Observation The recurrent genome proportion in the substitution lines was 87.59%.
- Observation The donor genome proportion in the substitution lines was 7.64%.
- Observation Strong segregation distortion was found on chromosomes 3 and 6.
- Observation Transgressive segregation was observed for several traits in the population.
- Observation A highly significant QTL controlling resistance to Rice stripe necrosis virus was mapped on chromosome 11 between SSR markers RM202-RM26406.
- Observation The mapping of the RSNV locus is the first identification of a genetic factor underlying resistance to this virus.
- Recommendation The population is a powerful breeding tool.
- Recommendation CSSL libraries with entire genome coverage are a useful strategy for QTL discovery.
- Observation The population helps overcome hybrid sterility barriers between rice species.
- Mechanism The segregation distortion on chromosomes 3 and 6 indicates interspecific sterility genes.
