Fig. 1. Frequency distributions of least-squares means for seed yield of doubled haploid (DH) lines from two populations (MF and RV) grown in Wisconsin and testcross progenies (T x MF and T x RV hybrids) grown in Saskatchewan and Wisconsin during 1999 and 2000. The arrows indicate seed yields of the tester (T), the parents of the DH lines (MF = MF216, R = RV128 and P = P1804), the starting hybrid (T x P), the open-pollinated (OP) and hybrid (H) cultivars, and the overall mean (M) of each population. Horizontal lines below each histogram indicate the LSD at the 0.05 probability level.
