regeneration and evaluation of cultivated species of Solanaceae (Egg Plant, Tomato, Pepper) commenced nced since continued in ٢٦ provinces of Iranduring ١٣٨٤-١٣٨٧. A total of ٢٨٦ accessions of (Tomato),٢٢٨ accessions of (Egg Plant) and ١٣٢ accessions of (Pepper) were collected according to the descriptor of IPGRI.Characterisks of collection sites includings, latitude, water and soil types, and topographical conditions affecting the climate were recorded according to IPGRI descriptor at the time of sampling. In order to regenerate sufficient genetic material, the collected samples were categorized climatically according to the location of collection and sent to related research centers in the fifth year of the project. Regenerated samples were then resent to headquarter in Karaj which currently preserved in two active and basal collections in a packaged form so that in case of need by breeders or students to exploit this germplasm in breeding or development of new varieties or academic researches, the sufficient material and recorded data would be available. The accessions under study were cultivated in Karaj in order to identify and evaluate qualitative and morphological traits and the results were used to study the correlations among the traits. Collected accessions were planted in two meters long rows wids ٧٥ (tomato١٥٠) cm inter-rows distance in research field of Seed and Plant Improvement Institute. The plants were irrigated weekly and no fertilizer or fungicide was used during cultivation practice. A total of ten samples out of ٢٨٦ collected genetic resources of Tomato, ٢٠samples out of ٢٢٨ collected genetic resources of Egg Plant ٤٣samples out of and ٤٠ samples out of ١٣٢ collected genetic resources of Pepper failed to germinate and therefore were removed form the cycle of preserving and data recording. Some qualitative traits such as corolla colour,Fruit size and fruit blossom end shape,Fruit shoulder shape, fruit length and fruit width in ٢٨٦ accessions were evaluated which were identified as (tomato). The results indicated the existence of positive correlation of corolla colour, with the fruit size and negative correlations of colour of immature fruit and presence of green trips on the fruit of tomato .Some qualitative traits such as leaf blade size, Intensity of leaf blade green colour, plant height, fruit shape , fruit length were evaluated in ٢٢٨ accessions which were identified as (Egg Plant). The results indicated the existence of positive correlation of of immature fruit colour and negative correlations of fruit size with flower intensies of purple colour at ١% level of confidence.Some qualitative traits such as head fruit shape , fruit shape ,plant height, fruit number were evaluated in ٧٦ accessions of pepper. The results indicated the existence of positive correlation of head fruit shape with fruit shape and negative correlations of plant height with fruit number at ١% level of confidence.
