Clonal Reproduction of Transplanted Rhizomes of I. fulva, I. hexagona, and Their F1 and F2 Hybrids. (A) Probability of new ramet production. Data show least-squares means + 1 se of genotype means for each plant class at each site (i.e., means are adjusted for the effect of rhizome mass). (B) Proportional change in rhizome mass. Bars sharing a letter within each site do not differ significantly at P < 0.05 after adjustment for multiple comparisons (from Emms and Arnold, 1997).

Linkage Map and Genomic Positions of QTL Affecting Species-Specific Vegetative and Floral Characteristics Found in H. annuus and H. debilis ssp cucumerifolius. Horizontal lines indicate genetic marker locations, with their designations given below each linkage group. Map distances between markers are indicated by numerals to the left of linkage groups. QTL positions and the magnitude of their effect are indicated to the right of the linkage groups (from Kim and Rieseberg, 1999).
