Dominance values and direct test for monogenic inheritance of type II resistance in CpR5M and CpR5S.

Dominance values were calculated according to Bourguet [26] using the mortality rates given in Table 1. A direct test of monogenic inheritance for resistance to CpGV-M or CpGV-S [27] was conducted by comparing expected and observed mortality of the backcrosses subjected to CpGV-M and CpGV-S, respectively. Asterisks indicate significant differences from a monogenic model (χ2 test, df = 1; *P value < 0.05).
