Abstract :

The present investigation was carried out at experimental research farm of Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu at Chatha during 2019-20 and 2020-21. Eight genetically diverse cultivars of strawberry were selected based on their genetic value and crossed through hand self-pollination and caging methods of pollination to produce inbreed lines of cultivars. After crossing of genetically superior parent by two different pollination methods viz., hand self-pollination and pollination by caging, Nabila showed best results among different cultivars. In hand self-pollination, fruit set after 21 days was found to be maximum in Nabila cultivar i.e. 83.32 % and 85.40 % within two growing season, respectively. Simultaneously, cultivars Nabila showed maximum fruit retention (82.90 % and 84.63 %), fruit weight (30.12 g and 31.16 g), fruit length (38.60 mm and 42.70 mm), fruit breadth (43.20 mm and 44.22 mm), number of achenes per fruit (411.75 and 435.75), achene density (17.77 cm2 and 15.66 cm2), respectively. However, cv. Jutog Special showed lowest performance among all these parameters. In self-pollination by caging, fruit set after 21 days was found in cv. Rania (60.32 % and 61.44 %), fruit retention in cv. Nabila (62.18 % and 64.70 %), fruit weight in cv. Nabila (16.49 g and 17.26 g), fruit length in cv. Rania (25.86 mm) in 2019-20 and cv. Nabila (28.13 mm) in 2020-21, fruit breadth in cv. Nabila (16.16 mm and 16.26 mm), number of achenes per fruit (246.32 and 251.14) and achenes density (22.77 cm2) in 2019-20 and 24.06 cm2 in Sweet Charlie in 2020-21. However, maximum fruit set after 21 days were recorded by hand self pollination methods which resulted into maximum fruit retention, fruit weight, fruit length, fruit breadth etc. as compared to self pollination through caging. Hand self-pollination methods is best methods to develop fruit under controlled condition and ensure the pollination in strawberry cultivars to develop inbred lines.
