text_original: When working on these lines with plants which are readily cross fertilised, such for instance as turnips or mangels, it is necessary to enclose the original individual plants, and the subsequent separate plots, so as to prevent them from crossing with plants of other lines, in which case the progeny would be cross bred and not the progeny of a single plant. This of course enormously increases the difficulty of carrying out the experiment.
