Abstract
Recombination experiments involving a series of two-factor crosses have been done with ts mutants of the baculovirus, Autographa californica nuclear poly-hedrosis virus (NVP). Six mutants which fail to produce non-occluded virus at 33 °C (NOV mutants) have been ordered on a linear genetic map.
