Project Title:
Near-isoline Gene for Tillering in Spring Wheat
Objective:
To test agronomic performance of gene pairs of spring wheat genetic lines with tillering traits.
Personnel:
J.A. Torrion, Daniel Porter, Jason Cook
Summary:
Six tiller near-isoline gene pairs were studied to examine the performance of genes with high tiller compared with the no tiller gene check. This study was in a randomized complete block with three replications. The six gene pairs were planted at lower and higher seeding rates (16 and 24 live seeds/ft2). Detailed management is provided in Table 1. There were no yield differences among the genetic lines regardless of seeding rates (Table 2). The plant height of entry 19 and 20 are the tallest, whereas entry 2 is the shortest regardless of seeding rates. Protein ranged 13.6% (entry 16 at 16 seeding rate) to 15.5% (entry 19 at 24 seeding rate). Both entries 1 and 2 had low test weights compared with the rest of the entries. Entries 19 and 20, showed the largest seed size, as shown in the thousand kernel weights. Falling number quality analysis were above the market critical levels and ranging from 407 (entry 16 at 16 seeding rate) to 483 (entry 2 at 16 seeding rate).
