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.
