Evaluation of Spring Wheat near isogenic lines - 2017
To generate preliminary agronomic performance data on NILs with improved competitive traits.
The 2017 growing season was characterized by high temperatures and low rainfall, which restricts the interpretation of this non-replicated trial. Within the tiller lines yields ranged from 38.21 for tiller 20 to 49.62 for tiller 15. Protein varied from a low of 14.4 for tiller 2 to a high of 16.39 for tiller 19. Test weights ranged from a high of 59.9 for tiller 15 and tiller 20 to a low of 57.2 for tiller 1. Thousand kernel weights ranged from a high of 39.3 for tiller 19 to a low of 30.2 for tiller 16. Falling numbers were high and varied from 511 for tiller 1 to 438 for tiller 16.
Within the protein lines, yields ranged from 26.5 for HGPC 14 to 39.98 for HGPC 4. Protein varied from a low of 13.83 for HGPC 13 to a high of 16.98 for HGPC 5. In contrast, test weights ranged from a low of 54.7 for HGPC 5 to a high of 60.2 for HGPC 13. Thousand kernel weight ranged from a low of 26.4 for HGPC 11 to a high of 36.1 for HGPC 3. Falling numbers ranged from a low of 383 for HGPC 5 to a high of 543 for HGPC 7.
