  • Estimates of broad-sense heritability (Ĥ2) on an entry-mean basis are reported. Field trials were conducted from 2010 to 2012 at the Maricopa Agricultural Center located in Maricopa, AZ. BLUE, best linear unbiased estimators; RIL, recombinant inbred line; WL, water-limited conditions; WW, well-watered conditions; ABA, abscisic acid; CID, carbon isotope discrimination; LUI, length uniformity index.
