The research was conducted at Institute of Hydroponics, PMAS Arid Agriculture University Rawalpindi. The selected crop for this research was tomato (Solanum lycopersicon L) Belongs to the solanaceae family. After maize, rice, wheat, potatoes, soybeans, and cassava, it is the seventh most significant crop of the world. It is one of the versatile and the most important vegetable crop of world, which is known for its potential to add important nutrient to healthy diet. The indigenous tomato cultivars were not studied under unheated greenhouse before in Pakistan so the research was conducted to test the performance of 28 indigenous tomato genotypes under unheated greenhouse condition. Seeds were sown in 200 celled plastic trays. After 15 days when maximum seedlings were germinated germination percentage was calculated. 30 days old seedling were transplanted in the rock wool and placed them in plastic bags of 30 cm wide and 100 cm long filled with coco-peat under unheated greenhouse. All the plants were applied with standard cultural practices. Data of the parameters were collected at 15 days interval. Maximum number of leaves and the tallest plants were found in the variety (v20) super. (v27) saffal f1 showed earliest and (v9) bgs-30 showed latest flower and fruit emergence. Maximum flower cluster and maximum number of fruit per plant was seen in (v11) rio grande gaint cluster had biggest fruit size and 17905 had smallest fruit size among the tested genotypes. Gaint cluster gained maximum and (v10) scarlet had lightest single fruit weight. Average yield per plant was maximum in (v25) robin f1 and minimum in 17905.

To evaluate the performance of 28 indigenous tomato genotypes under unheated greenhouse conditions in soil-less media to identify cultivars with early and high yields.
Twenty-eight indeterminate tomato genotypes were evaluated in a completely randomized design (CRD) with three replications under an unheated greenhouse at the Institute of Hydroponics, PMAS Arid Agriculture University Rawalpindi. Seeds were sown in plastic trays, and 30-day-old seedlings were transplanted into plastic bags filled with coco-peat. Standard cultural practices were applied. Data on various growth and yield parameters were collected at 15-day intervals. Statistical analysis was performed using Statistic 8.1 software, applying CRD and comparing means using LSD.

The study highlights the variability in performance among different tomato genotypes under unheated greenhouse conditions. The differences in growth and yield parameters are attributed to the genetic potential of the genotypes and their interaction with the environment.
Significant differences were observed among the genotypes for various parameters. The variety 'Super Red' had the maximum number of leaves and plant height. 'Saffal F1' showed the earliest flower emergence, while 'Bsg-30' showed the latest. 'Rio Grande' had the maximum number of flower clusters and fruits per plant. 'Gaint Cluster' had the biggest fruit size, while '17905' had the smallest. 'Robin F1' had the maximum average yield per plant, and '17905' had the minimum.
The variety 'Robin F1' is identified as the best-performing genotype for yield under unheated greenhouse conditions. The findings provide valuable information for selecting suitable tomato cultivars for hydroponic production in Pakistan.
