 About LjMG RILines

 

Recombinant inbred lines

Recombinant inbred lines (RILs) are mapping population, which can be maintained eternally as seeds.
The F2 genotypes generated between homo lines are fixed by self-crossing. The conserved recombination patterns become a powerful tool in genome analysis, such as gene mapping. Also, phenotypic variations inherent in RILs allow an accurate genetic analysis as a consequence of feasibility of strain dependent traits evaluation and repetitive experiments.

About"LjMG RILines"

"LjMG RILines" are RILs between Miyakojima MG-20 and Gifu B-129. These RILs were established at Kazusa DNA Res. Inst., by self-crossing 8 times the F2 seeds provided by Kawaguchi (The Univ. Tokyo).
In 2004, they have completed establishing 205 lines.

Currently, the two parents of "LjMG RILines", Miyakojima MG-20 and Gifu B-129, are the most commonly used experimental accessions. Kawaguchi has established the accession Miyakojima MG-20 by self-crossing 7 times the collection from Miyakojima among the Southwest Islands. This accession is characterized by the short generation time. On the other hand, Gifu B-129 was the first one to be established as an experimental accession, collected by Hirayoshi (Kyoto Univ.), named Gifu B-129 by Grant, and self-crossed 9 times by Stougaard.

At Kazusa DNA Res. Inst., genotyping of the RILines is in progress by SSR markers covering the entire genome. A search for the genotype data is available in this database. A search is also available for the phenotypic data evaluated at Miyazaki (N. L. 31° , Long. 131 ° E) and Sapporo (N. L. 43 ° , Long. 141 ° E).
