Fig. 1. Distribution of PPO activity (L-DOPA and L-tyrosine) for M6/Opata 85 (A), NY18/CC (B), and ND2603/Butte 86 (C) recombinant inbred lines. Arrows indicate parental means. CF98 is Central Ferry, 1998; FD94 is Wooster, field, 1994; and GH94 is Wooster, greenhouse, 1994. For the NY18/CC population, the parental values for 1998 were not available. The averages indicated are based on the 1994 field and greenhouse growouts. In C the PPO activity is the average for the 1997 and 1998 data for both Pullman and Bozeman.
