Registration of ‘Tom’ Wheat

Abstract

‘Tom’ (Reg. No. CV‐1069, PI 656383) hard red spring wheat (Triticum aestivum L.) was developed by the University of Minnesota Agricultural Experiment Station and released in 2008. Tom was tested as MN01311‐A or MN01311‐A‐1 in statewide yield trials from 2005 to 2007 and in the Uniform Hard Red Spring Wheat Regional Nursery in 2004 and 2005. Tom was released based on its high grain yield, moderate resistance to Fusarium head blight (caused primarily by Fusarium graminearum Schwabe), and adult‐plant resistance to race TTKSK (Ug99) of stem rust (Puccinia graminis Pers.:Pers. f. sp. tritici Eriks. & E. Henn.). Tom is well adapted to the hard red spring wheat growing regions in Minnesota and the Upper Midwest.

Registration of ‘Rollag’ Spring Wheat

“…Rollag is a mid‐maturity cultivar, averaging 58.5 d from planting to heading in Minnesota locations from 2008 to 2010 (Table 1). This is similar to ‘Tom’ (Anderson et al, 2012). Rollag is shorter than average at 77.5 cm, measured from soil level to the tip of the spike, excluding awns (Table 1).…”

“…Rollag is shorter than average at 77.5 cm, measured from soil level to the tip of the spike, excluding awns (Table 1). This height is not significantly different than the long‐term check ‘Marshall’ (79.1 cm) (Busch et al, 1983) but is significantly shorter than ‘RB07’ (79.9 cm) (Anderson et al, 2009) and Tom (83.3 cm) (Anderson et al, 2012). Rollag has very good straw strength, with an average score of 1.2 on a scale of 0 to 9 across 15 locations where differential lodging occurred from 2008 to 2010 (Table 1).…”

Registration of ‘Sabin’ Wheat

“…Sabin is shorter than average at 78.6 cm, measured from soil level to the tip of the spike, excluding awns (Table 1). This height is not significantly different from that of Faller (81.0 cm), ‘RB07’ (77.8 cm; PI 652930; Anderson et al, 2009), and ‘Tom’ (81.0 cm; PI 656383; Anderson et al, 2012). The straw strength of Sabin is worse than average compared with that of other cultivars, with a score of 3.4 on a 0–9 scale (0 = no lodging; 9 = completely flat) in the six locations where some lodging occurred from 2006 to 2008 (Table 1).…”

“…Sabin is shorter than average at 78.6 cm, measured from soil level to the tip of the spike, excluding awns (Table 1). This height is not signifi cantly different from that of Faller (81.0 cm), 'RB07' (77.8 cm; PI 652930; Anderson et al, 2009), and 'Tom' (81.0 cm; PI 656383; Anderson et al, 2012). The straw strength of Sabin many of the common races, Sabin showed a relatively low leaf rust severity under conditions of high inoculum pressure in 2007 (Table 3) and after inoculation of adult plants with a mixture of races in Crookston and St. Paul, MN (data not shown).…”

Nested Association Mapping of Stem Rust Resistance in Wheat Using Genotyping by Sequencing

“…In the St. Paul 2012 environment, lines were planted in 2 m long single rows with 20 cm between the rows. The populations were planted in an augmented design with 4 check varieties ‘Oklee’ [ 34 ], ‘Thatcher’ [ 35 ], ‘Tom’ [ 36 ], and ‘Verde’ [ 37 ] planted after every 30 entries. In the St. Paul 2013 environment, lines were planted in hill-plots with 20 cm distance between the hills.…”
