| 0 | PI 656383 | 'Tom' | Triticum aestivum L. subsp. aestivum | Minnesota, United States | PVPO | | Not Available | 2009 | DEVELOPED | 2009 | | | | | Cultivar | Hard red spring wheat. Tom heads in an average of 57 d from planting in Minnesota locations. It has average plant height, averaging 81.0 cm. Tom is moderately resistant to leaf rust under field conditions and is susceptible to the common races MLOS and TDGJ in seedling tests. Based on seedling resistance Tom likely has either Lrl6 or Lr23. The results of ON A marker testing indicate that Tom contains the adult plant resistance gene Lr34. It is highly resistant to the prevalent race QFCSC and other important North American stem rust races (QTHJC, RCRSC, RK.QQC, TPMKC, and TTTTF) at the seedling and adult plant stages. Since the beginning of field evaluations in 1999, natural infection by stem rust on Tom has not been observed. Tom has shown moderate resistance to TTKSK (syn. Ug99) when evaluated in stem rust nurseries in Kenya in 2005, 2006, and 2007. Tom's reaction is similar to 'Thatcher' in reaction to Ug99 in seedling and adult plant stages. It has been evaluated in FHB nurseries since 2001 and has moderate resistance to this disease. Tom's FHB moderate resistance is due to reduced spread of disease within spikes (i.e. Type 2 resistance). Tom has good end-use quality, comparable to most other cultivars currently grown in the hard red spring wheat growing region of the Upper Midwest.. Tom contains the 2* and 5+10 subunits of the Glu-AI and Glu-Dlloci, respectively that have been positively correlated with bread-making quality. | 1797065 | PI 656383 |
