Table 3.

Mean contents of carbon, hydrogen, and nitrogen of the pod valves as applied to the following comparisons: two parental lines MG38 (dehiscent) vs. MIDAS (indehiscent); indehiscent vs. dehiscent introgression lines; and introgression lines with < 7.14 vs. ≥7.14% shattering pods.

Groups of introgression lines with different letters have significantly different means (P < 0.05; Tukey-Kramer multiple comparison tests).
