Summary
Selection has been practised for high and low final height in a population of 81 highly inbred lines derived by single seed descent from a random sample of the F2 of the cross of varieties 1 and 5 of Nicotiana rustica in the poorest, best and average of 15 environments. The properties of the resulting selections show that the high selection made in the best environment has a greater environmental sensitivity than that made in the poorest environment while the low selection made in the best environment has a lower environmental sensitivity than that made in the poorest environment. The selections made in the average environment have intermediate environmental sensitivities. These selections confirm the rules laid down by Jinks and Connolly (1975) relating the environmental sensitivities of selections to the selection environment.
