Abstract
Abstract Potato tubers of Solanum tuberosum cv. Kennebec, produced at elevations from 1533 to 3198 m at 2 levels of insolation per site were grown in a greenhouse at 1533 m to determine the effect of the parental clone's environment on the performance of the succeeding generation. Rate of emergence, early vegetative growth, and tuber growth increased with increasing elevation of the parental clone but there was no significant difference in vegetative growth or tuber yield at vine senescence. The environment of the parental clone had no direct influence on the photosynthetic activity of the clonal progeny, but an inverse relationship between bulking efficiency and altitude of seed tuber production was evident. Shading of the parental clone at each elevation had little influence on the succeeding generation.
