Abstract/Contents: | "Festulolium is an intergeneric hybrid between Lolium and Festuca species that may possess the agronomic advantages of both genera. As a result of DNA recombination, the chromosomes in festulolium are striped with DNA from the two genera. Using genomic in situ hybridization and image analysis techniques, we determined the genomic constitution of festulolium using the ratio of Festuca-specific genome regions to the whole genome (the F ratio). The F ratio of a festulolium cultivar is expected to reveal its phenotypic tendency, particularly quantitative traits that differ clearly between Lolium and Festuca, such as persistency, drought resistance and seed yield. The objective of this study was to clarify the variability of the F ratio among cultivars, in order to determine how many plants were required to estimate the F ratio of a cultivar. We investigated the F ratios of five cultivars and found that they were significantly different. 'Paulita' had the highest F ratio (approximately 33%), followed by 'Tandem' and 'Tohoku 1' (approximately 18%) and 'Evergreen' and 'Icarus' (approximately 6%). Given the unbiased variance in the F ratios of 'Icarus,' which had the largest number of tested plants, we concluded that seven plants were more than sufficient to distinguish among cultivars whose F ratios differed by 10 points at a significance level of 0.05." |
