MS breeding lines, Mississippi breeding lines; IL breeding lines, Illinois breeding lines; R8, full maturity stage; within a year, trait, and row, means with the same letter are not significantly different.
The experiment was conducted in 2012 and 2013 at the Jamie Whitten Delta States Research Center, Stoneville, MS.
Means within a row followed by the same letter are not significantly different at the 5% level as determined by Fishers' LSD test.
