Seven strawberry cultivars were taken for pollination studies (selfing by bagging, open pollination, hand self pollination and cross pollination). Cross pollination increased fruit length (41.15 mm in ‘Gorella’ x ‘Chandler’) and fruit breadth (34.10 mm in ‘Confectura x Gorella’) and reduced fruit malformation (3.40 % in ‘Chandler x Gorella’) compared to other pollination methods, whereas selfing by bagging reduced fruit size (15.09 mm length in ‘Sweet Charlie’ and 10.80 mm breadth in ‘Gorella’) and increased fruit malformation of 52.99 per cent in ‘Sweet Charlie’. Achene density ranged from 23.63 to 19.91/cm2 in selfing by bagging and cross pollination, respectively. As berry deformity is severe problem in commercial cultivation of strawberries influencing marketable yield. Cross pollination had profound role on reducing fruit deformities and increasing quality in terms of fruit length and breadth indicating necessity of compatible pollinizers and pollinators to ensure adequate quality and yield in strawberry field.
