Comparison of spike and floret characters measured in synthetic allotetraploids (S1 generation), <i>B</i>. <i>distachyon</i>, <i>B</i>. <i>stacei</i> and natural <i>B</i>. <i>hybridum</i>.

<p>MPV1 = Mid-parent value: average of <i>B</i>. <i>distachyon</i> Bd21 and <i>B</i>. stacei ABR114 parent values; MPV2: average of <i>B</i>. <i>distachyon</i> Bd3-1 and <i>B</i>. <i>stacei</i> Bsta5 parent values. See <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0167171#pone.0167171.s002" target="_blank">S2 Fig</a> for the specific characters scored and <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0167171#pone.0167171.s006" target="_blank">S3 Table</a> for further details. There were no seeds from S1 plants of allo21×114, therefore seed number per inflorescence and percent of fertile florets were not scored.
