29. Characterization and performance evaluation of tomato genotypes grown under unheated greenhouse condition
Main Article Content
Abstract
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.
