The Canadian Food Inspection Agencys Plant and Biotechnology Risk Assessment PBRA Unit is responsible for assessing the potential risk to the environment from the release of plants with novel traits PNTs into the Canadian environment. The PBRA Unit is also responsible for assessing the pest potential of plant imports and plant species new to Canada. Risk assessments conducted by the PBRA Unit require biological information about the plant species being assessed. Therefore, these assessments can be done in conjunction with species specific biology documents that provide the necessary biological information. When a PNT is assessed, these biology documents serve as companion documents to Dir. Assessment Criteria for Determining Environmental Safety of Plants with Novel Traits. Scope. This document is intended to provide background information on the biology of Solanum tuberosum, its identity, geographical distribution, reproductive biology, related species, the potential for gene introgression from S. Such information will be used during risk assessments conducted by the PBRA Unit.

S. tuberosum has been placed in the section Petota, which includes all of the tuber bearing wild and cultivated potatoes.

Solanum tuberosum is a herbaceous plant that grows to 0. Spooner and Knapp 2. Stems range from nearly hairless to densely hairy and may be green, purple, or mottled green and purple. Leaves are pinnate with a single terminal leaflet and three or four pairs of large, ovoid leaflets with smaller ones in between Spooner and Knapp 2. Struik 2. 00. 7. The blades range in size from 8 2. They are medium to dark green, and like the stems, may range in hairiness from nearly hairless to densely hairy on both sides. S. tuberosum plants produce rhizomes often called stolons that have rudimentary leaves and are typically hooked at the tip. They originate from the basal stem nodes, typically below ground, with up to three rhizomes per node Struik 2. Tubers, spherical to ovoid in shape, are swellings of the rhizome. The flesh of the tubers varies in colour from white to yellow to blue and the skin varies from white through yellow to tan and from red through blue. The colour of the flesh may or may not correspond to the colour of the skin. The texture of the surface may vary from smooth to netted or russetted Spooner and Salas 2. On the surface of the tuber are axillary buds with scars of scale leaves that are called eyes Struik 2. When tubers are planted, the eyes develop into stems to form the next vegetative generation. The terminal inflorescences are cymes that are 5 1. Spooner and Knapp 2. Struik 2. 00. 7. The inflorescences are usually branched and may contain up to 2. The peduncle is 0 2. The pentamerous flowers, 3 4 cm in diameter, are all apparently perfect with styles of the same length Sleper and Poehlman 2. Spooner and Knapp 2. The corolla may be a range of colours, including white, pink, lilac, blue, purple, and red purple. The colour may be uniform or the pointed tips of the petal lobes may be white or there may be a second colour either stippled, in bands or in a star, and this may occur on either side of the corolla Spooner and Knapp 2. The petals are fused to create a tubular flower Sleper and Poehlman 2.
