The methods were applied on data obtained from 41 seed orchard clones of Scots pine from mid-Sweden. The value of the seed orchard crop was set as a function of its breeding value, the amount of seeds produced and their gene diversity, measured as the effective number of clones. The proportion of ramets of different clones that maximized this value was regarded as the optimum for deployment of the clones in a seed orchard. The results were compared with truncation selection for breeding value, truncation selection for clone benefit ( the product of seed production and breeding value) and linear deployment ( where ramets are deployed linearly in relation to breeding value). The influence of two parameters was studied: the relative importance of breeding value for seed value and the size of the penalty for reducing the value of the seed crop with respect to lost gene diversity. The conventional wisdom is to select the clones with the highest breeding values, but that turned out to be the most inferior alternative studied. Clone benefit truncation provided a good approximation to optimal benefit for cases, where the effective number was low and dependence of breeding value limited.},
