TABLE 1.
Description of the number of genotypes, composition, and experimental design of two generations of F4:7 advanced nurseries (ADV), and F4:8 elite nurseries (ARE), as well as the initial training population (TP18_FHB) used to predict three Fusarium head blight (FHB) resistance traits, including deoxynivalenol (DON) accumulation, Fusarium damaged kernels (FDK), and severity (SEV).
| Triala | Generationb | Conventional lines | DH lines | Total | Location(s) | Rep(s) | Designc |
| TP18_FHB | – | 355 | – | 355 | 9 | 2 | RCBD |
| ADV18 | F4:7/DH | 64 | 40 | 104 | 2 | 2 | RCBD |
| ADV19 | F4:7/DH | 50 | 70 | 120 | 2 | 2 | RCBD |
| ARE19 | F4:8/DH | 16 | 6 | 22 | 2 | 2 | RCBD |
| ARE20 | F4:8/DH | 12 | 11 | 23 | 1 | 2 | RCBD |
aTrial types and the years each were grown. TP18_FHB was grown over four years between 2013–2014 and 2016–2017; 18, 2017–2018; 19, 2018–2019; 20, 2019–2020.
bBreeding trials consisted of conventionally bred genotypes as well as doubled haploid (DH) genotypes.
cRCBD, randomized complete block design.
