Comparision of eight tomato cultivars (Lycopersicon esculentum Mill)‎ in Sulaimani governorate

الملخص EN

This study was carried out from (March to October 2014) at two different locations )Bakrajo and Kanipanka( in Sulaimani governorate to compare some chemical and physical properties and genetic diversity of eight tomato cultivars "Sangaw", "Early Person", "Dimond Star" ,"Guja Faranji", "Aljinan" ,"Egemen" " Heinz 2274" and "Sun" using RCBD design with four replications and the results shows that "Sangaw" had higher value of fruit equatorial diameter and lower value of polar diameter which gave it a broad shape, with lowest firmness .

Whereas "Sun" had gave a long cylindrical shape and the highest value of firmness obtained from "Sun".

Fruits of "Sangaw" cultivar was superior in their Lycopene, Total acidity% and pH contents .

"Early Person" had higher amount of Ascorbic acid, whereas "Dimond Star" gave maximum values of total sugar% "Guja Faranji" was superior in total soluble solid (Brix %), total soluble solid/ total acidity and dry matter% .

Random Amplified Polymorphic DNA (RAPD) analysis was carried out on (8) tomato cultivars by (4) primers (OPB-18, OPC-08, OPC-09 and OPV-19).

The genetic similarity among evaluated cultivars ranged from (0.4) to (1.00).

The lowest genetic distance was (0.4) between "Sangaw" and "Egemen" cultivars which means that the presence of similarity is high, while the highest genetic distance was (1.0) existed among "Sun" , "Sangaw" , "Dimoned Star", "Guja Faranji", "Aljinan" and "Egemen" which means that presence of similarity is low.
