Evaluation of physico-chemical characterization of tomato (Lycopersicon esculentum Mill.) germplasm
Abstract
Eleven tomato germplasm (Cherry tomato, Rio Grande, Gala, Kalam, Red Star, Roma VF, Taj, Peshawar Local, Bambino, Roma and Roma King) of edible tomato (Lycopersicon esculentum Mill.) were investigated at The University of Agriculture Peshawar during 2017. The aim of this experiment was to evaluate and select tomato germplasm, which could be grown for raw material production and future breeding, taking into account their nutrition composition. The statistically analyzed data indicated that tomato germplasm were highly significant (P ≥ 0.01) in physical and chemical contributing parameters. Physical and chemical data of different tomato fruits at harvesting stage indicated that maximum fruit weight (81.3g) and highest Ascorbic acid content (14.64 mg 100 g-1) was found in tomato cv. Gala. Maximum fruit firmness (2.07) was observed in variety Roma. Maximum percent juice content (91.8 %) were taken by tomato germplasmKalam. Maximum Total Soluble Solid (TSS) (4.8) was measured in tomato germplasm Bambino, whereas maximum (0.37%) acidity was measured in cv. Rio Grande. Maximum (4.63) fruit pH was recorded in germplasm Roma King, which statistically at par with fruit pH (4.56) observed in tomato variety Bambino. It was established that according to above results the tomato cv. Gala and Rio Grande performed best in physical and chemical contributing parameters for quality attributes. These tomatoes cultivars can be grown for raw material production and may be used in future breeding.
