| Volunteers from genetically modified (GM) potatoes may pose an environmental problemif allowed to grow in the field after the annual crop is harvested. We tested whether they are more likely to produce volunteers than non-GM potatoes. Specifically, we compared the number of volunteers, number of tubers per plant, tuber size, and their vertical distribution in the soil. More volunteer plants came from non-GM potatoes than from GM potatoes, but the number and size of tubers were similar between the two. Vertical distribution of the tubers differed significantly, with most non-GM tubers being found in shallower soil (<2 cm deep). Our results suggest that spontaneous GM volunteers may emerge and produce tubers to a degree similar to that of the non-GM plants. No viable volunteers emerged from GM tubers in the next growing season, probably deterred by winter frost and a period of low soil temperatures (below $-2^{circ}C$) at our study site. However, in regions with warmer climates, such GM volunteers may survive Winter and produce more plants the following year. |
