“…Van Gelder et al (1988) concluded that this required further study in wild species. It is also important in early maturing commercial cultivars where there is a strong market demand for small tubers harvested before the plants mature and senesce.…”

SummaryPlants of early potato cultivars were sampled at successive harvests during tuber development and individual tubers were analysed for ct-solanine and (x-chaconine using high-performance liquid chromatography. Mean tuber total glycoalkaloid concentration (ct-solanine plus ~t-chaconine) per plant decreased with time and statistically significant differences between cultivars were observed in the patterns of decline during tuber growth. The mean tuber ratio of t~-chaconine to tx-solanine increased during tuber development and was also affected by genotype. Total glycoalkaloid concentration for individual tubers of marketable sizes (up to 50 g fresh weight) exceeded the safety limit of 20 mg per 100 g fresh weight for cultivars Home Guard and British Queen but not for Rocket. These differences were attributable to differences in both rates and patterns of glycoalkaloid accumulation during tuber development, although in all cultivars results were consistent with glycoalkaloid accumulation occurring in the expanding peripheral cell layers of tubers for a considerable period after tuber initiation.

“…Wild potatoes contain a variety of glycoalkaloids, often in concentrations far greater than observed in cultivated potatoes (van Gelder et al ., 1988) . Excessive total glycoalkaloids are associated with undesirable flavor and mammalian toxicity and teratogenicity (Gregory et al ., 1981) .…”

The past 25 years, 1686 potato accessions, representing 100 species in the genus Solanum L ., subgenus Potatoe, section Petota, were evaluated for field resistance to one or more of the following insect pests : green peach aphid, Myzus persicae (Sulzer) ; potato aphid, Macrosiphum euphorbiae (Thomas) ; Colorado potato beetle, Leptinotarsa decemlineata (Say) ; potato flea beetle, Epitrix cucumeris (Harris) ; and potato leafhopper, Empoasca fabae (Harris) . Accessions highly resistant to green peach aphid were identified within 36 species, to potato aphid within 24 species, to Colorado potato beetle within 10 species, to potato flea beetle within 25 species, and to potato leafhopper within 39 species . Resistance levels were characteristic within Solanum species . Insect resistance appears to be a primitive trait in wild potatoes . Susceptibility was most common in the primitive and cultivated Tuberosa . Insect resistance was also characteristic of the most advanced species . The glycoalkaloid tomatine was associated with field resistance to Colorado potato beetle and potato leafhopper . Other glycoalkaloids were not associated with field resistance at the species level .Dense hairs were associated with resistance to green peach aphid, potato flea beetle, and potato leafhopper .Glandular trichomes were associated with field resistance to Colorado potato beetle, potato flea beetle, and potato leafhopper . Significant correlations between insect score and altitude of original collection were observed in six of thirteen species . Species from hot and arid areas were associated with resistance to

“…Therefore low levels of glycoalkaloids in the tubers are a prerequisite. The expression of glycoalkaloids may differ between leaves and tuber of a potato plant, as was reported by Gelder et al (1988) and Friedman (2006), which may open possibilities for breeding varieties with high levels of glycoalkaloids in the leaves and low levels in the tubers.…”

“…Tomatine and aglycone solanidine, two other glycoalkaloid, have also been reported for their role in resistance to CPB (Barbour and Kennedy 1991;Kowalski et al 2000). Tomatine is present in many Solanum species (Gelder et al 1988), including tuber-bearing wild relatives of potato such as S. okadae (Pelletier et al 2001) and S. neocardenasii (Dimock et al 1986).…”

The Colorado potato beetle (CPB) is one of the pest insects that significantly can decrease the production of potato when no control measures are taken. The fast, flexible and diverse life cycle of the CPB, its highly destructive feeding habits, and high adaptability to a variety of environment stresses, have made the control of CPB a difficult task. This paper briefly reviews the information on all aspects of CPB management to come to an integrated pest management approach: the biology of the CPB, management practices including their limitations and drawbacks, as well as the need to incorporate host plant resistance into potato varieties. Several aspects of potato breeding for resistance to CPB are discussed. We evaluate the availability of natural variation present in potato wild relatives, the considerations in choosing a specific wild relative, and constraints in using them from biological, environmental and genetic point of view, in which newly developed technologies play an important role. We also consider recently developed GM approaches. We conclude that varieties resistant to CPB are desperately needed by farmers and demanded by society, and that the means to develop them are available.
