Abstract: Collecting the best quality seed from an openpollinated seed orchard requires the understanding and manipulating a wide variety of factors. gSOOP is an Excel spreadsheet that allows seed orchard managers to evaluate various management options based on the best understanding of the factors affect seed genetic quality. It takes as its starting point a description of groups of trees in the orchard in terms of their count, genetic value for harvest volume and basic density, and fecundity. Separate management may be applied to each group of trees, although all are assumed to contribute to the pollen cloud. Each group may be thinned phenotypically for growth or wood quality traits in up to 2 stages, or eliminated altogether. The effect of screening for self-compatability is used to increase the effetive outcrossing of the orchard. Finally, harvesting may be confined to groups according to their genetic value or fecundity. The harvest is summarised in terms of the genetic value for wood production traits and overall economic value of the seed produced and the cost of producing it. The system has been used by Australian seed orchard mangers to evaluate different management options to boost seed quality
