    Abstract Objective: To systematically investigate the effect of CT localizer radiograph acquisition on the tube current modulation and thus radiation dose of the subsequent diagnostic scan.
    Methods: Localizer radiographs of an abdominal section CT phantom were taken, and the resulting volume CT dose index (CTDIvol) for the diagnostic scan was recorded. Variables included tube potential, the phantom's alignment within the CT scanner gantry in both the vertical and horizontal directions and the X-ray source angle at which the localizer was acquired.
    Results: Diagnostic scan CTDIvol decreased with increasing tube potential. Vertical (table height) movement was found to affect radiation dose more than horizontal movement, with ±50 mm table movement resulting in a standard deviation in the diagnostic scan CTDIvol of 4.4 mGy, compared with 2.5 mGy with ±50 mm horizontal movement. Correspondingly, localizer angles of 90° or 270° (3 o'clock and 9 o'clock X-ray source positions) were less sensitive overall to alignment errors, with a standard deviation of 2.5 mGy, compared with a 0° or 180° angle, which had a standard deviation of 3.8 mGy.
    Conclusion: To achieve a consistently optimized radiation dose, the localizer protocol should be paired with the diagnostic acquisition protocol. A final acquisition angle of 90° should be used when possible to minimize dose variation resulting from alignment errors.
    Advances in knowledge: Localizer parameters that affect radiation output were identified for this scanner system. The importance of tube potential and acquisition angle was highlighted.

    Abstract Two experiments were conducted to measure the effect of gene , on seed yield and seven other agronomic traits by comparing closely related soybean [ (L.) Merr.] lines differing in resistance and susceptibility to f. sp. , Kuan and Erwin, in environments where the disease was not evident. In Exp. 1, seven resistant () and seven susceptible ((,) lines from each of six crosses were grown in replicated field tests near Morris, Rosemount, and Waseca, MN in 1975 and 1976. In Exp. 2, six pairs of nearisogenic lines, differing in Phytophthora reaction within each pair, from each of the third, fourth, and fifth generations of a backcross program were grown in replicated field tests near Rosemount and Waseca in 1976. On the basis of means representing 630 observations in Exp. 1 and 108 observations in Exp. 2, we concluded that resistant and susceptible lines were not significantly different for maturity, lodging, plant height, seed yield, seed quality, seed size, seed protein, or seed oil in either experiment. There was no convincing evidence of any genetic association between the , gene and any of the agronomic traits studied.

    Abstract Two populations of soybeans, (L.) Merr., each having at least one parent with high percent seed protein, were studied to determine the effects of selection for percent protein in an early generation (F or F) upon percent seed protein, percent seed oil, and seed yield in later generations (F and F). The populations were stratified as follows: from 60 F plants in one population the 10 highest, the 10 lowest, and 10 intermediate in percent protein were selected; similarly, from 60 F lines of the other population the 10 highest, 10 lowest, and 10 intermediate in protein were selected. Resulting F lines of both populations were grown in replicated yield tests at two locations. On the basis of mean percent protein in these tests, the five highest lines of the high group, the five lowest of the low, and five intermediate from the intermediate group of each population were identified. Two plant progenies of each selected line were advanced to the F generation and grown in replicated yield tests at two locations. There was a significant correlation between early generations and subsequent generations for percent protein indicating that early classification of plants or lines is useful. Although there was a negative ~orrelation between percent protein and seed yield and between percent protein and percent oil, F lines with desirable combinations of percent protein, percent oil, and seed yield were identified. The majority of these lines traced to the intermediate protein stratum established in the early generation.
