Evaluation of Heat-Tolerance on Different Eggplants
In order to make clear the heat-tolerance of the inbred lines and their combinations,consequently enhance the predictability for breeding heat-tolerant parents and their combinations,rapid evaluation system during seedlings was employed to identify the difference for heat-tolerance among 43 breeding lines,7 target combinations and 3 F1 hybrids.By two indicators,heat-injury index and relative conductivity of the membrane,11 inbred lines had strong heat-resistance,while 8 inbred lines had weak heat-resistance and 24 inbred lines had medium heat-resistance.The combinations both parents with strong heat-tolerance were also showed strong heat-tolerance.In addition,it was found that the leaf thickness,to some extent,was associated with heat-tolerance in eggplants.
