Evaluation of tomato cultivars (Lycoperiscon Esculentum Mill)‎ under high temperature conditions

Abstract EN

An experiment was carried out to test the ability of tomato cultivars to set fruit under high temperature (32-36°Cday) and (20-24°C night).

The experiment was carried out in a greenhouse where the temperature is controlled by an evaporative cooling system.

The response of the tom ato cultivars to high temperature varied greatly.

The Burgess cultivar produced the highest yield and best quality fruit under the high temperature regime .

The Saladeue cultivar showed good performance and produced satisfactory results in a variety of characteristics such as the ability to se t fruit.

resistance to splitting, and absence of an exerted style protruding from the anteridial-cone : The S6~ ln variety has excellent ability to set fruit and produce a high flower number.

However, the fruits were very small and highly susceptible to splitting.

The Michigan-Ohio cultivar seeded more than any other stra in or cultivar, N 5~FI and Carmello F1 produced the highest percentage of total soluble solids in the fruit juice .

The results of this research indicate thai several cultivars were suitable for use in arid regions.

and it will be possible to dev elop a cultivar with superior qualities which produces high yield under arid conditions .
