Assembling of hybrid varieties that had superior agronomic character in plant breeding programs was by crossing two or more plants that have superior character. The present study was carried out at the Department of Fruit Science, Dr YS Parmar University of Horticulture and Forestry with the aim of studying the performance of strawberry F1 hybrids and parents for flowering, fruiting and vegetative parameters in field conditions. Seven strawberry cultivars were crossed in all possible combinations to provide a total of 42 F1 hybrids and seven inbred lines used as parents. Among hybrids, ‘Gorella x Selva’ (8/2/17) was earliest in initiation of flowering followed by ‘Chandler x Ofra’ (11/2/17). F1 Hybrid ‘Sweet Charlie x Chandler’ flowered late (16/3/17). ‘Gorella’ among parental lines, was earliest in flowering (10/2/17). On the other hand, ‘Addie’ was earliest in completion (end) of flowering (21/3/17). Hybrid combination ‘Gorella x Selva’ completed flowering very soon (10/3/17). Fruit weight ranged from 7.02 to 9.73 g among parents. Hybrid combination ‘Gorella x Chandler’ had heaviest fruit (15.64 g). Maximum number of fruit per plant was in parental line ‘Gorella’ (17.31) whereas amongst F1 hybrids, it was in ‘Chandler x Gorella’ (28.59) which was statistically at par with ‘Selva x Gorella’ (26.47). Plant height ranged from 16.52 cm (Addie) to 25.87 cm (Gorella) among parental lines. ‘Selva x Chandler’ (28.61 cm) produced maximum plant height. Leaf number among parents and F1 hybrids varied from 17.56 to 21.58 and 16.74 to 26.48 respectively. Hybrid, ‘Chandler x Gorella’ (26.48) registered maximum leaf number.
