Texas A&M AgriLife staff in College Station, Amarillo/Lubbock, Vernon, Lubbock, and Corpus Christi have designated our annual wheat grain variety “Picks” for the 2019-2020 growing season for four distinct variety testing regions of Texas. These are the High Plains, Rolling Plains (Chillicothe/Vernon region in the north to south of Abilene), Blacklands & Northeast Texas, and South Texas.
Continuing a tradition established years ago, our ongoing Picks criteria include a minimum of three years of irrigated or dryland data in Texas A&M AgriLife regional variety trials across numerous annual locations.
Furthermore, a “Pick” variety means this: “Given the data these are the varieties we would choose to include and emphasize on our farm for wheat grain production.”

Picks are not necessarily the numerical top yielders as important disease resistance traits (leaf or stripe rust, wheat streak mosaic virus), insect tolerance (greenbugs, Russian wheat aphid, wheat curl mite Hessian fly), or standability can also be important varietal traits that enable a producer to better manage potential risk.

Continuing Pick Varieties
TAM 112 remains on the limited irrigated and dryland Picks Lists because of its’ drought tolerance and resistance to the wheat curl mite, which provides tolerance to wheat streak mosaic virus. Be aware though that TAM 112, unlike most of our other Picks, is susceptible to leaf and stripe rust. TAM 113 remains on the list because of solid grain performance, forage potential, and ability to emerge under stressful conditions. It has moderate resistance to stipe and leaf rusts. Likewise, TAM 114 continues as a strong Pick with good yields and a solid rust resistance package. This variety to date has been the common replacement for TAM 111, which was removed from the Picks list two years ago due to increasingly inconsistent performance.
Table 1. Texas A&M AgriLife wheat grain variety Picks for the Texas High Plains based on yield performance and consistency based on over 34 multi-year, multi-site irrigated, and dryland trials harvested in 2015-2019. Leaf rust and stripe rust reactions are included (see footnote).

Westbred Winterhawk, Westbred WB4721 and Limagrain LCS Mint have continued to perform well in the past 4+ years Texas High Plains production. Dyna-Gro Long Branch will remain on the watch list. It has a good grain yield potential, but milling properties are not as good as other varieties and test weights are below average. Limagrain T158 remains on the dryland list because of continued good performance under dryland conditions.
Changes in the High Plains Picks for 2019-2020
Croplan CP7869 has been evaluated as Croplan EXP 69-16 since the 2016-2017 production year. Released in 2018, it is well adapted for both irrigated and dryland conditions. In all years, it has been a top-yielding variety with good test weights, straw strength and a leaf disease package (good resistance to leaf, stem, and stripe rust). Syngenta Monument is another addition for the irrigated Picks Lists. It has been a top yielder in the High Plains Uniform Variety irrigated trials for 4+ years with good test weights. It is resistant to stripe and leaf rust and noted for very good drought tolerance. It was not placed on the dryland Picks List because it was not evaluated in 2018-2019 dryland trials.
OSU’s Iba was dropped because it has not maintained an upper yield potential compared to newer varieties. Both TAM 304 and Limagrain T158 were dropped from the irrigated lists. TAM 304 does not have the upper yield potential of newer varieties, and T158 was no longer evaluated in 2018-2019 High Plains irrigated trials.
Changes in the Watch List
TAM 115 is a new variety on the 2019-2020 Irrigated and Dryland Picks Watch Lists. It has a solid 3-year history in the High Plains Uniform Variety trials especially in the limited irrigated and dryland trials. It has previously been evaluated as an experimental variety. TAM 115 is a dual-purpose variety resistant to leaf rust, stripe rust, stem rust, green bug and wheat curl mite (hence lower susceptibility to wheat streak mosaic virus) with excellent drought tolerance.
TAM 205 is a new addition to the 2019-2020 Irrigated and Dryland Picks Watch Lists. It has been evaluated for 2 years in the uniform variety trials. It is a dual-purpose variety with a high top-end yield potential, good test weights, and good fall forage production. It is resistant to leaf rust, stripe rust, stem rust, and green bug. It is also resistant to the wheat curl mite and wheat streak mosaic virus. It performed very well in the irrigated and dryland trials.
Both TAM 115 and TAM 205 will have limited seed availability in fall 2019, so we are not sure how widely available seed will be for the upcoming planting year.
We removed PlainsGold Avery (Colorado variety) from our watch list as ongoing results are insufficient to promote the variety to the Picks list for dryland.
Additional discussion of wheat grain variety Picks for the High Plains (with multi-year yield tables) will be posted at http://lubbock.tamu.edu/programs/crops/wheat/ by August 26, 2019.
Northern Rolling Plains Wheat Grain & Dual-Purpose Picks for 2019-2020
Dr. Emi Kimura, Extension agronomist, Vernon, (940) 552-9941, email@example.com
In the past AgriLife has reported a Picks List for all of the Rolling Plains, from south of Abilene/Concho Valley to the Wichita Falls/Chillicothe area. This year’s list focuses on data from trial sites only from Abilene north, hence we are designating it as the ‘Northern’ Rolling Plains Pick list. Also, Dr. Kimura, is testing forage and subsequent grain yields for dual-purpose wheats. This is AgriLife’s first list—Watch varieties due to two years of data—for this category in 2019-2020. We will look to develop a list of wheat variety selections more focused on the Lower Rolling Plains through Dr. Reagan Noland, San Angelo, (325) 657-7330, firstname.lastname@example.org, will be developing a list of Picks and Watch varieties based on Brady, Millersview, as well as the same Abilene trials Dr. Kimura uses.

Leaf rust/stripe rust resistance ratings: R, Resistant; MR, moderately resistant; MS, moderately susceptible; and S, susceptible.
Additions in 2019
Syngenta SY Drifter and Westbred WB 4269 were added to the Northern Rolling Plains grain only Picks List in 2019 due to consistently good yields. Yields were comparable to other Pick List varieties. SY Drifter is a medium maturity with good leaf and stripe rust resistance. WB 4269 is medium early maturity and is moderately resistant to stripe rust but needs fungicide application for leaf rust.
New for 2019-2020 is Dr. Kimura’s Watch list for Northern Rolling Plains (Abilene north) for varieties that have a good combination of good grazing and subsequent grain yield. These five varieties will continue in testing with other lines to establish a Picks list for 2020-2021.
Deletions in 2019
Greer and WB Cedar were removed from the grain only Picks list due to inconsistent yields.
Blacklands/Northeast Texas Wheat Grain Picks for 2019-2020

|WB 4418 (S/MR)|
Additions for 2019
While no varieties were added to the HRWW Picks List, AGS 2024 and AGS 2038 were added to the Picks for soft red winter wheat (SRWW). Westbred WB 4418 and WB 4303 remain on the Watch List for the Blacklands due to growing indications of good yield and other traits. Both WB 4418 and WB 4303 are intermediate on leaf and stripe rust resistance and may require a fungicide in the spring to maximize yields. Both are ranked high for straw strength as well. WB 4418 also has good Hessian fly tolerance which is an important trait in this region, whereas WB 4303 is rated excellent for grazing potential.
Deletions for 2019
After being on the Picks List for several years, Greer was finally dropped from the HRWW list after slipping in the yield rankings for two years in a row. Coker 9553 was also dropped from the SRWW list due to discontinued seed sales.
Westbred WB Cedar has had some average results in individual trials but has a very strong yield history. This variety is shorter in height with excellent straw strength, early maturity and good test weight. Leaf rust resistance has broken down however, and it is susceptible to stipe rust in the juvenile stage. If producers manage foliar diseases with fungicide, WB Cedar should still perform well. Also, WB Cedar has shown vernalization issues in the southern tip of the Blacklands during mild winters.
South Texas Wheat Grain Picks for 2019-2020

|Wheat Variety “Watch” List, South Texas, 2019-2020|
|WB 4303 (S/MS)||WB 9350 (S/MR)|
Additions for 2019
No new additions for 2019-2020. Westbred WB 9350 remains on the HRSW Watch List. This variety was only tested in 2017 and 2019, thus additional performance data will be needed before additional changes are considered.
Deletions for 2019
LCS Iguana (HRSW) and SY Cypress (SRWW) were deleted as Picks.
It appears TAM 401 remains the sole hard red winter wheat entry for South Texas as it is the least sensitive winter type to vernalization issues that are a regular issue during mild winters. It is awnless and has lighter test weight, but still maintains good resistance to leaf and stripe rust and is one of the earliest maturing winter varieties available. Unfortunately, there is little if any seed availability remaining for this variety. Producers who can find a little, especially if certified, may wish to save some of their grain for their own planting (if permitted by Texas Dept. of Agriculture). We don’t have any other stronger, more certain options than TAM 401 for South Texas. Westbred WB 4303 is on the watch list for this region as it too appears less sensitive to the mild winters. In portions of South Texas, hard red spring wheats are a safer bet to avoid vernalization problems.
