Abstract
The resistance of the resistant sorghum line KS 30 and the susceptible hybrid RS 671 to biotype C of Schizaphis graminum (Rond.) was determined under 3 temperature regimens (10.0-21.1, 14.6-26.7 and 21.1-32.2 deg C) and with plants growing in 7 different nutrient solutions. In general, resistance decreased as the temperature decreased. However, resistance was also influenced by the type of nutrients; changes in the nutrient supply altered the level of tolerance rather than antibiosis. Resistant plants growing in solutions containing excess potassium exhibited the highest resistance under all 3 temperature regimens.ADDITIONAL ABSTRACT:The level of resistance of the resistant sorghum cv. KS 30 and the susceptible cv. RS 671 to greenbugs (Schizaphis graminum) at day/night temp. of 21/10 deg , 26/16 deg or 32/21 deg C and in 7 different nutrient sol. was investigated. At the lower temp. resistance was lowered and was influenced by the nutrients applied to the plant. Changes in nutrient supply varied the level of tolerance more than antibiosis. Resistant plants growing in excess K sol. achieved the highest resistance compared with susceptible plants under all temp. regimes
