Narrative

To produce synthetic hexaploid wheat germplasm with resistance to Fusarium head blight (FHB), hybrids were initiated between Langdon (CItr 13165) durum wheat (T. turgidum ssp. durum) with a T. dicoccoides 3A chromosome substitution and two different accessions of T. tauschii ssp. squarrosa. The T. dicoccoides 3A substitution is the source of the FHB resistance. A chemical doubling of the chromosome number of the hybrids resulted in the production of synthetic hexaploid wheat germplasm lines with the genome constitution AABBDD. The mean FHB spike severity ratings during two greenhouse evaluations were 44 and 47% which are comparable to or significantly lower than the 56 and 99% ratings for LDN(3AA)-32, the FHB resistant source parent. A cold treatment was benefical in breaking seed dormancy and promoting seed germination. Exhibited a spring growth habit and extensive tillering, and matured somewhat late, flowering 84 to 92 d from germination under greenhouse conditions compared with 54 d for Alsen, 63 d for McNeal, and 75 d for Langdon. Comparable to Langdon durum in height, ranging from 115 to 133 cm tall under greenhouse conditions. [See PI 634196-634199 for accessions from the same Crop Science registration.]
