Tomato (Lycopersicon esculentum Miller) is being grown universally, in Kashmir, however only few cultivars without any scientific documentation are being grown having poor yield and susceptible to various disease and frost damage. The existing germplasm from Azad Jammu & Kashmir, Pakistan was characterized morpho-genetically during the year 2002-2003 at Rawalakot to determine the variability among the cultivars and to identify some selectable markers based on total seed protein profiles. The purpose of the investigation was to develop new varieties based on genetical variability among the cultivars and to document the germplasm for future record. The comparison was based on yield and growth characters including plant height (135-145cm), number of trusses per plant (52-132), number of flowers per truss (18-27), number of flowers per plant (933-3955), number of fruit per plant (158-1017), fruit size (38- 45cm), number of locules per fruit (3 8.5 - 45.65), leaf area (8-10cm2), length of the internodes (7-13cm) and 10 fruits weight (1016-2017g), revealed significant variability among the cultivars. The total seed proteins comparisons based on SDS-PAGE profile did not indicate variability among the major bands, however some miner bands were found to be variable in terms of distance traveled in the gel. The investigation indicated that genetic diversity does exist among the local cultivars and the germplasm could be utilized for breeding new varieties suitable for the area by even using the conventional techniques of selection and hybridization.
