Abstract

Hybrid wheat breeding programs need to use chemical hybridizing agents for seed production due to its simplicity. Alternative methods such as cytoplasmic systems or hand pollinations restrict genetic combinations or seed production which limits testing experimental hybrids in large-scale multi-environment trials (METs). Using F2 seed instead of F1 can allow programs to test hybrid cross combinations in METs and the data can be used to supplement selection decisions at early stages of breeding cycle. To test this hypothesis, two METs consisting of 40 entries were conducted in 2017 and 2018 in six locations across Texas and Nebraska. The entries included hybrids at the F2 stage and their respective parents, selected from a previous preliminary F1 evaluation experiment. In six out of 10 test environments, a F2 hybrid had statistically significant higher yield than highest yielding parent. The F2 mid-parent heterosis ranged from − 20.97 to 27.52% in 2017 and − 9.90 to 9.17% in 2018. The F2 high-parent heterosis ranged from − 21.07 to 17.85% in 2017 and − 16.57 to 6.68% in 2018. The heterosis estimates of these cross combinations at F1 stage were extracted from previous large scale METs conducted on nine environments across Nebraska and Texas in 2016–2017. A comparison of F2 heterosis from this study and F1 heterosis from the previous study revealed that F2 heterosis was highly indicative of superior F1 performance. The results provide strong evidence for utility of F2 yield data in selecting superior F1 hybrids. In addition, a practical framework for using F2 performance to aid selecting F1's in a hybrid wheat-breeding pipeline is provided. [ABSTRACT FROM AUTHOR]

Abstract

Genome wide association studies (GWAS) were conducted to identify net blotch (net form: caused by Pyrenophora teres f. teres) resistance loci in Ethiopia and Eritrea (EEBC) barley landraces and the elite germplasm of the Barley Coordinated Agricultural Project (Barley CAP). Two quantitative trait loci (chromosomes 5H and 6H) were identified in the EEBC. Resistance QTL were found in chromosomes 4H and 6H in the two-row panel, chromosomes 3H and 6H in the six-row panel and in chromosomes 3H, 4H, 6H and at an unmapped location in the combined Barley CAP germplasm. The distribution of Barley yellow dwarf (BYD), caused by Barley/cereal yellow dwarf virus (B/CYDV) in the Luteovirus family, in Minnesota was studied using 243 cereals and grass samples collected from 2013 to 2015. Reverse transcription polymerase chain reaction using virus strain specific primers revealed that BYDV-PAV was the most prevalent strain of B/CYDV.
