This table presents the regression of accession site-of-origin characteristics on the square root of total fruit production, including all plants and after removal of the effects of spatial block.

Regression on each factor was performed independently. The regression of Gower's environmental distance statistic is presented at the bottom. All models had 20 degrees of freedom.
