Summary
A simple statistical test of the equality of the means of B1 B2 and F2 families and the means of the corresponding L1, L2 and L3 generations of an F2 triple test-cross is described which specifically detects linkage between genes displaying non-allelic interactions in the presence of other complex effects. The test is used to confirm that linked interacting genes contribute to the variation in final height and flowering time in the cross between varieties 1 and 5 of Nicotiana rustica.
