Fig. 1. Frequency histograms of damage and reproductive adaptation scores of recombinant inbred lines (RILs) tested for resistance to Thrips palmi in three seasons (1999A, 1999B, and 2000B). Repetitions: 1, 3, 3; number of lines: 94, 94, 48, respectively. The overall mean is indicated by a solid line. Parents BAT 881 (B) and G 21212 (G) are indicated by black triangles; the five most susceptible lines (5S), and five most resistant lines (5R) are indicated by white triangles. Resistant, intermediate, and susceptible intervals are indicated at the bottom of the figure. Means and standard errors are given in Table 3.
