a
Reflectance measurements indicate relative R-r expression through its effects on kernel pigmentation. Average measurement values ±SD+ are presented for the total number of testcross individuals shown in parentheses. Measurements indicating absence of r1 paramutation are in italics.
b
A two-sample t-test was applied to the null hypothesis that differences between average measurements derived from R-st/R-r; +/rmr6-1 and R-st/R-r; rmr6-1/rmr6-1 genotypes are due to random chance.
