Domestic Breeding

When covering the results of evaluation of potato varieties domestic breeding for resistance to Colorado potato beetle (Leptinotarsa decemlineata Say.). The effect of resistant potato varieties on the physiological state of the Colorado potato beetle, and the degree of damage to the leaf surface of plants at different periods of vegetation. Allocated relatively resistant to Colorado beetle of potato varieties: Vedruska, Vimir, Vodograi, Glazurna, Serpanok, Povin.

Growing Conditions

AbstractSolanum berthaultii Hawkes bears trichomes reportedly providing resistance to insects. Results indicated that the density of types A and B trichomes was linearly related to the inverse of the leaflet area. The number of trichomes on the adaxial and on the abaxial surface of terminal leaflets was not affected by two levels of water stress or by growing conditions in the greenhouse or the field. The leaflets of the water-stressed plants were generally smaller and, consequently, the density of trichomes higher.The survival of first-instar Colorado potato beetle larvae was similar on S. berthaultii grown under varying drought conditions and on leaves from field-grown plants bearing different densities of trichomes.
