Spike phenotypes of F1 and F2 hybrids derived from the crosses of T. turgidum PI 67339 (shr2), T. durum R-107 (wfzp-A/TtBH-A1) and T. turgidum K-40750 (wfzp-A/TtBH-A1). a to d, spikes of the parental lines (a), F1 (b) and F2 (c, d) hybrids derived from the PI 67339/K-40750 cross. e to h, spikes of the parental lines (e), F1 (f) and F2 hybrids (g, h) derived from the PI 67339/R-107 cross. c and g, F2-spikes, representing different phenotypic classes: false-true ramification (f-tR), turgidum type of branching (T.t.- branching), ramified spike (RS), horizontal spikelet (HS), standard or WT-spike (WT). D, F2-spike of additive phenotype (left) harboring an extra spikelet (supernumerary spikelet, SS) (middle) and an elongated spikelet of f-tR-type (right) at one rachis node. H, A spike of additive phenotype (right) with the SS and f-tR-type spikelets at one rachis node (left). gl – glumes, l – lemma, pa – palea, asterisks indicate ectopic spikelets
