Figure 10 shows the
Hill plot corresponding to PCS loss index with a 95 percent confidence interval.
Although the
Hill plot is linear well below 58% oxygen saturation, the error in calculated [P.sub.50] increases rapidly below this point primarily because of the propagation of error in measured P[O.sub.2].
To answer this question in the present study, we looked at the correlation between spikelet severity in injected spikes and FDK in a sample of grain from auxiliary, noninjected spikes in the same
hill plot. The strength of this design is that it allowed us to assess the value of the injection method in the field within the same experimental unit, thus eliminating noise caused by plot-to-plot environmental variation.
The 63 S0:1 full-sib families were evaluated in replicated
hill plot field experiments grown at one or two locations.
To provide a pool of pods at the same stage of development, a minimum of 20 3-seeded pods per
hill plot (at two pods per plant) were marked with acrylic paint (Egli, 1999), at the beginning seedfill stage (BS, pods were dark green, seeds were green and just starting to swell with a 3-4 mm diam.).
Cycle and check means for oil content, grain yield, groat fraction, and oil yield for oat lines representing nine cycles of recurrent selection evaluated in
hill plot experiments in three Iowa locations in 1992.
Subsequently, 100 spikes selected from the [F.sub.3] were threshed individually and sown as [F.sub.3:4]
hill plots in the FHB nursery at Prosper, ND, in the summer of 1998.
The experiment was planted in
hill plots with 12 seeds per plot.
The experiment was planted on 5 June 1995 in
hill plots with 12 seeds per plot.
The [F.sub.4] generation was evaluated for maturity, height, and disease resistance as 30
hill plots, each containing grain from a single [F.sub.3] spike.

A balanced composite of 46 [S.sub.1] seeds from each half-sib family used in the second intermating were planted in
hill plots spaced 1.0 m apart in all directions, and alternated with
hill plots containing [S.sub.0] seed from the second intermating.
