Interpretive Summary: NE15420 is a hard red winter wheat (Triticum aestivum L.) cultivar developed cooperatively by the Nebraska Agricultural Experiment Station and the USDA-ARS. It is being released primarily for its superior adaptation to irrigated wheat production systems throughout Nebraska, which require strong straw, short stature, and high yield potential. In field tests, NE15420 demonstrated good straw strength, little to no lodging and was classified as a semi-dwarf wheat. Additionally, the grain volume weight and winter hardiness was similar to widely grown cultivars in Nebraska. In the last three years, it has been tested in the irrigated trials in the Nebraska State Variety Trials across 4 environments and was the second highest yielding line and not significantly different from WBB418 and WB-Grainfield, Long Branch, AM Eastwood, and CP7869, but was significantly higher yielding than Wesley (a very popular irrigated wheat cultivar known for its strong straw). End-use quality tests for milling and baking indicated NE15420 was very similar to check cultivars Wesley and LCS Valiant. Based on these observations, NE15420 is being released for its excellent grain yield potential and acceptable end-use quality traits for seed production under irrigation in the state of Nebraska.

Technical Abstract: NE15420 is a hard red winter wheat (Triticum aestivum L.) cultivar developed cooperatively by the Nebraska Agricultural Experiment Station and the USDA-ARS. It is being released primarily for its superior adaptation to irrigated wheat production systems throughout Nebraska, which require strong straw, short stature, and high yield potential. NE15420 has excellent grain yield for seed production under irrigation. It also demonstrated good straw strength, little to no lodging and was classified as a semi-dwarf wheat possessing the RhtB1b allele for plant height. Additionally, the grain volume weight and winter hardiness was similar to widely grown cultivars in Nebraska. In the last three years, it has been tested in the irrigated trials in the Nebraska State Variety Trials across 4 environments and was the second highest yielding line and not significantly different from WBB418 and WB-Grainfield, Long Branch, AM Eastwood, and CP7869, but was significantly higher yielding than Wesley (a very popular irrigated wheat cultivar known for its strong straw). NE15420 is resistant to Soilborne wheat mosaic virus in field nurseries in Nebraska. It is resistant to stem rust (caused by Puccinia graminis Pers.: Pers. f. sp. tritici Eriks & E. Henn.) in field nursery tests at St. Paul, MN and moderately resistant to stripe rust (caused by P. striiformis Westendorp f. sp. tritici), in field nurseries in Nebraska.By molecular markers, it is believed to carry the following genes or translocations: Sbm1, Lr24/Sr24, and Lr37/Sr38/Yr17. NE15420 is moderately susceptible to Fusarium head blight (caused by Fusarium graminearum, data from greenhouse and field observations in Nebraska and Kansas) and moderately susceptible to DON accumulation. NE15420 is susceptible to Hessian fly (Mayetiola destructor Say,). Based on genomic data, it is expected to be susceptible to Wheat streak mosaic virus. The milling and baking properties of NE15420 were determined for five years by the Nebraska Wheat Quality Laboratory and for most traits, NE15420 was very similar to check Wesley and LCS Valiant although NE15420 may be slightly lower in flour yield and slightly higher in four protein and ash content, water absorption and Mixtime. However, NE15420 should be acceptable to the milling and baking industries based on end-use quality performance tests.
