Comparison of 16 Phenotypic Traits in Synthetic Triploid Hybrid (Robertsii.3x.syn) Monkeyflowers (Mimulus spp.) and Their Synthetic Allohexaploid Derivatives (Peregrinus.6x.syn) Measured in a Common Garden in the Greenhouse.

The traits measured were: days to flowering (FLTI), plant height (PLAH), flowering node of the first flower (FLNO), corolla width (CORW), corolla height (CORH), corolla tube length (TUBL), throat opening (THRO), throat width (THRW), calyx length (CALL), pedicle length (PEDL), the width (LEAW) and length (LEAL) of the largest leaf, bract width (BRAW) and length (BRAL), anther-stigma distance (ASD), and stem thickness (STTH). All units are in millimeters except FLTI (days) and FLNO (flower number). Statistical significance of differences between the triploid and the allohexaploids was assessed by MANOVA. ∗P < 0.05; ∗∗P < 0.01; ∗∗∗P < 0.001.
