13.—(1) A population developed under the experiment must be identifiable on the basis of—
(a)the varieties used in crossing to generate it;
(b)the techniques used in crossing;
(c)the degree of heterogeneity;
(d)a description of its characteristics; and
(e)whether it can be reproduced unchanged once established in a specified region of production with specified agro-climatic conditions.
(2) The technique used in crossing to generate the population must include one or more of the following—
(a)the crossing of several different varieties of plants, using crossing protocols to produce diverse heterogeneous material by bulking of the progeny, in order to produce material with a high level of genetic diversity;
(b)on-farm management practices which include selecting, establishing or maintaining material characterised by a high level of genetic diversity;
(c)any other technique used for the breeding or production of heterogeneous material and specified in the participant’s licence.
(3) For the purposes of paragraph (2), “bulking of the progeny” means repeatedly re-sowing and exposing the stock to natural or human selection.
