Ullah Tomato, combining ability, single and double cross hybrids, yield 23-29 7 (1) 2023 January 2023 This study was conducted to assessment of combining ability of single and double cross hybrids (Solanum lycoperson Mill) of tomatoes from 2018 to 2019 in the farmersand#39; fields of village Tarar, Rawalakot, AJK. This trial was set up in RCBD with 3 replicates. Twelve tomato hybrids were obtained by a 4×4 diallel fashion in 1^st year and were evaluated for plant attributes i.e., number of branches per plant, number of cluster per plant, number of locules per fruit, plant height, fruit drop, number of flowers per cluster, pericarp thickness, number of fruits per cluster, single fruit weight, fruit diameter and fruit yield per plant in the second year. Among the parents Sahel and Dinar has good GCA for fruits per plant, single fruit weight and yield per plant and could be used in hybridization for yield improvement. While crosses Sahel × Dinar, Sandal × Dinar and Sandel × Sahel had better SCA for single fruit weight and yield per plant and need further evaluation for yield stability at multilocations.
