T-CAP Germplasm

  • Three soft and hard winter wheat cultivars from ID with good yield performance under water limited conditions, to be released in 2011.

IDO599 (SWS), IDO671 (SWS), IDO694 (HWS)

  • The solid-stem variety ‘SY Tyra’ (resistant to wheat stem sawfly) was developed by marker assisted backcrossing in collaboration between Montana State University and Syngenta and is being marketed in Montana and North Dakota.
  • Two high quality durum wheat varieties: “Desert King- High Protein” and “Tipai” selected with molecular markers for improved grain protein content (GPC-B1), improved semolina color (PSY1 A-B hybrid allele) and higher pasta color stability (lipoxygenase deletion).
  • Two hard red winter wheat from Nebraska Breeding program: ‘NE01481’ and ‘NI04421’.
  • The dual-purpose variety ‘Duster’ was released by the Oklahoma State University and is well adapted to the southern Great Plains of the USA.
  • CSU released three new varieties: Byrd, Denali, and Brawl CL Plus. Byrd is a high yielding variety under both dryland and irrigated conditions, carries stripe rust resistance and an unknown source of Ug-99 stem rust resistance, and has excellent milling and baking quality. Denali has shown excellent yields across the High Plains. Brawl CL Plus is the first public two-gene Clearfield wheat, showing comparable yields as other Colorado Clearfield varieties in addition to improved stripe rust resistance, test weight, and milling and baking quality
  • Four barley varieties released in 2011 were Atlantic, Voyager, Transit and Verdant.

Germplasm releases

Two adapted hard red spring wheat donor lines carrying three new stripe rust resistance QTLs (Lowe et al. 2011, TAG. 123:143–157).

  • GSTR 13606 (RIL148 UC1110 x PI610750) = QYr.ucw-3BS, Yr48 (5AL), & QYr.ucw-2BS.
  • GSTR 13634 (RIL191 UC1110 x PI610750) = adapted spring donor line carrying stripe rust resistance QTL QYr.ucw-3BS, Yr48 (5AL), and QYr.ucw-2BS.

Two adapted spring donor lines carrying only the QYr.ucw-3BS stripe rust resistance QTL (i.e. they are susceptible for 5AL and 2BS).

  • GSTR 13600 (RIL140) = QYr.ucw-3BS alone.
  • GSTR 13664 (RIL233) = QYr.ucw-3BS alone.

Two adapted spring donor lines carrying only the stripe rust resistance locus Yr48 (i.e. they are susceptible for 3BS and 2BS).

  • GSTR 13504 (RIL4) = Yr48 alone.
  • GSTR 13618 (RIL167) = Yr48 alone.

Six isogenic lines of hexaploid wheat for vernalization alleles to provide access for wheat breeding programs to genes from elite cultivars possessing the alternate growth habit (Blake et al. 2011, JPR 5: 418-421).

Backcrossing introgression of the vrn-A1allele for winter growth habit into spring varieties

Mapping populations

  • Stripe rust resistance mapping population deposited in the NSGC: GSTR numbers 13501-13687= 186 recombinant inbred lines from the cross UC1110 x PI610750.
  • MN98550–5/MN99394–1 hexaploid wheat recombinant inbred mapping population. This population comprises 139 F6:8 recombinant inbred lines (RILs) adapted to the Upper Midwest region of the USA: PI 660540 MAP (MN98550–5) x PI 660541 MAP (and MN99394–1).
