| Outline of Final Research Achievements |
Linkage analysis was performed with a S1 population of strawberry derived from a Japanese variety, ‘Reiko’, a S1 population of sweetpotato derived from a Chinese variety, ‘Xushu 18’, and a F1 population cross between ‘Xhushu 18’ and an Ipomoea trifida accession, ‘K123-11’.
Although linkage maps were successfully constructed in the S1 populations of strawberry and sweetpotato, it was difficult to generate linkage groups in the sweetpotato F1 population with typical approach in linkage map construction. A sofrtware was developed for generation on linkage groups based on linkage disequilibrium (LD) between the two loci. The software calculates indexes representing LDs between the all combinations of two loci and constructing hierarchic structure based on the LD indexes.
