1measured as proportion of clones.
2measured as percentage sterile pollen.
Traits assessed in different environmental conditions (wet/dry) and in different years (2006/2007) are noted, along with the number of individuals analyzed for each trait (n). Effects in BCIB are the result of I. fulva alleles and effects in BCIF are the result of I. brevicaulis alleles. Location of each QTL is presented as the linkage group (LG) followed by position on the linkage group (in Kosambi cM). The likelihood ratio (LR), the additive effect, percentage of variance explained (R2) and the 2 LOD confidence interval are also presented.
