AB  - Stem solidness is an important agronomic trait for increasing the ability of 
      wheat to resist lodging. In this study, four new synthetic hexaploid wheat with 
      solid stems were developed from natural chromosome doubling of F(1) hybrids 
      between a solid-stemmed durum wheat (Triticum turgidum ssp. durum, 2n = 4x = 28, 
      AABB) and four Aegilops tauschii (2n = 2x = 14, DD) accessions. The solid 
      expression of the second internode at the base of the stem was stable for two 
      synthetic hexalpoid wheat Syn-SAU-117 and Syn-SAU-119 grown in both the 
      greenhouse and field. The lodging resistance of four synthetic solid-stem wheats 
      is stronger than that of CS, and Syn-SAU-116 has the strongest lodging 
      resistance, followed by Syn-SAU-119. The paraffin sections of the second 
      internode showed that four synthetic wheat lines had large outer diameters, 
      well-developed mechanical tissues, large number of vascular bundles, and similar 
      anatomical characteristics with solid-stemmed durum wheat. The chromosomal 
      composition of four synthetic hexaploid wheat was identified by FISH 
      (fluorescence in situ hybridization) using Oligo-pSc119.2-1 and Oligo-pTa535-1. 
      At adult stage, all four synthetic hexaploid wheat showed high resistance to 
      mixed physiological races of stripe rust pathogen (CYR31, CYR32, CYR33, CYR34). 
      These synthetic hexaploid wheat lines provide new materials for the improvement 
      of common wheat.
