Abstract
he present investigation was carried out on ‘Evaluation of strawberry (Fragaria anasassa
Duch.) cultivars under sub tropical conditions of Punjab’. Ten strawberry cultivars viz.
‘Chandler’, ‘Camarosa’, ‘Sweet Charlie’, ‘Antana’, ‘Ofra’, ‘Gorella’, ‘Brighten’, ‘Catispill’,
‘Elaranthra’, ‘Belrubi’ were characterized for morphogenetic characters under Ludhiana
(Punjab) agro climatic conditions. Plants were transplanted in 2nd fortnight of October,
2014-15 on raised beds of 5.0 m x 1.2 m. Plants were grown under uniform cultural practices
whereas fertilizers and irrigation were applied with drip irrigation at different intervals.
A wide range of variability among different cultivars was observed in vegetative, flowering
and fruit characters. ‘Antana’ cultivar had shown minimum (4.0%) plant mortality and the
highest production of runners/plant to the tune of 19.0 as compared to other strawberry
cultivars. Maximum plant height (13.4 cm) and petiole length (10.3 cm) was found in
‘Chandler’ and ‘Camarosa’ cultivars, respectively. The flowering was initiated after 64.8 days
after transplantation of runners in ‘Sweet Charlie’; whereas it was between 71.3 to 80.3 days
in the rest of strawberry cultivars. Maximum numbers of flowers per plant were found in
cultivar ‘Catispill’ (44.5) and ‘Antana’ (40.9) while least in ‘Ofra’ (19.3). Fruit length and
breadth ranged between 3.96 cm to 2.22 cm and 3.34 cm to 1.91 cm) respectively. Cultivars
‘Chandler’ and ‘Camarosa’ had the maximum marketable fruit weight (17.9, 18.4 g), fruit
yield/plant (246.1, 227.4 g) and fruit yield/acre (8.52, 7.82 MT) respectively. The maximum
TSS (9.5 0B), TSS/acid ratio (12.5) and Anthocyanin (66 mg/100g) while the total sugars
were higher in ‘Camarosa’ (6.64 %) and ‘Ofra’ had the maximum vitamin C content (88.1
mg/100 g) as compared to other cultivars under evaluation.
