2020 was a great comeback year for HRS after a wet dreary 2019. Harvest conditions were generally good in August and great in September. Yields were down a bit most places due to late spring field work and/or above average temperatures in June, but still respectable. Grain quality was generally good, a welcome relief after sprout damage with low falling numbers (FN) in 2019, with much of the crop left in the field due to cool wet conditions at harvest. FN was mostly a non issue in 2020 as it has been most years with some small pockets in NW MN, still something to watch. Bacterial leaf streak (BLS) continues to be a real yield killer as it was in 2019, especially in wet areas often associated with poorly drained heavy clay soils. It can not be controlled with fungicide. Generally scab was not a big issue in 2020. The 2020 HRS variety performance is reported in Table 1 with the 3-year summary in Table 2.
TCG-Spitfire continues to be an outstanding performer across years and environments for yield and standability, with medium protein. It has good tolerance to moisture stress and BLS which helps account for its wide adaptability. TCG-Spitfire is slightly susceptible to preharvest sprouting (PHS), so it should be harvested in a timely fashion. It is our most widely adapted variety.
TCG-Heartland performed very well in 2020 as an early, very high protein, high TW, good standing, high yielding variety. It performed best on well drained and medium to lighter soils. It stood up well to PHS pressure with good FNs in the areas affected in both 2020 and 2019. TCG-Heartland is a certified seed only (CSO) variety.
TCG-Wildcat, our newest variety, performed very well as a high yielding, high protein, high TW, management wheat for the RRV. It has an MS-S scab reaction but responds well to fungicide for scab. TCG-Wildcat is much like TCG-Spitfire, but has higher protein and TW, with earlier maturity, and quicker dry down and good tolerances to PHS. It has a good coping reaction to BLS, producing good yields and seed quality in the presence of BLS, but it does not have TCG-Spitfires BLS tolerance level. In its first year of limited commercial production it performed very well, both in and outside the RRV. TCG-Wildcat is a certified seed only (CSO) variety.
TCG-Wildfire continues to look very good as a high yielding, medium high protein option on water impacted alkali ground. Its tolerance to BLS has also been noted in these environments.
TCG-Glennville, as in 2019, continues to perform as a short, very early, good standing management HRS for good environments north of Highway 2. It can get pushed further south.
All the TCG HRS varieties are good standing management wheats in their areas of adaptation, with MS scab ratings of varying strengths. They are meant to be treated with fungicide at least once, at flowering.
