Objective:

To generate preliminary agronomic performance data on NILs with improved competitive traits.

Results:

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.
