Evaluation of tomato accessions for quantitative and qualitative traits under agro climatic condition of Peshawar
Main Article Content
Abstract
The objective of this research was to screen the tomato accessions for quantative and qualitative traits under agro climatic condition of Peshawar. 17 tomato accessions with a tomato commercial cultivar were evaluated in randomized complete block design with three replication at The University of Agriculture Peshawar, during kharif season 2016. Quantative traits studied were juice pH, total soluble solids, days to flowering, plant height, fruits plant-1, fruit weight and fruit yield plant-1. While qualitative traits comprised plant growth type, canopy size, leaf type, flower inflorance, fruit color, fruit shape and fruit firmness. Highly significant differences were observed among tomato accessions for all the quantative traits studied except juice pH. While qualitative traits showed that maximum accessions had indeterminate growth habit (88.9%), Intermediate canopy size (55.6%), curled leaf type (66.7%), medium number of flowers inflorescence-1 (55.6%), red fruit color (61.1%), deep globe fruits (26.7%) and soft fruit firmness (83.3%). Fruit yield plant-1 showed significant positive correlation with juice pH (r=0.580**), TSS (r=0.500**), plant height (r=0.420**), fruits plant-1 (r=0.410**) and fruit weight (r=0.920**) except days to flowering (r=-0.310**) which showed significant negative correlation with fruit yield plant-1. Roma showed highest value of fruit juice pH (4.1), total soluble solids (6.1), fruit weight (54.2 g) and fruit yield plant-1 (688.7 g). Therefor this study suggested that Roma and 31910 could be recommended as commercial cultivars under agro climatic condition of Peshawar and also could be used in future tomato breeding programs.
