Abstract/ Executive Summary:

Thirteen strawberry genotypes were evaluated at HRC, BARI during the winter season of 2009-2010 and 2010-2011 for yield and quality characters. Among the 13 genotypes studied, the plants of FA 005 produced the maximum number of fruits (43.50 plant^-1) followed by FA 006 and FA 007 (37.50 plant^-1), while FA 009 and FA 013 produced the minimum (9.00 plant^-1). The heaviest fruits were produced by FA 006 (18.73 g) followed by FA 007 (17.40 g) and FA 005 (16.96 g) which were statistically similar, while the lightest fruit was found in FA 014 (5.11 g). The fruit yield plant^-1 of different genotypes varied from 52.00 to 737.70 g and plants of FA 005 produced the maximum yield followed by FA 006 (702.30 g plant^-1). The minimum yield plant^-1was recorded in FA 013 and FA 014. The TSS content was highest in FA 007 (8.50 %), whereas the lowest was in FA 009 (6.33 %). The TSS to acid ration was maximum in FA 006 (11.32), while the lowest was in FA 011 (6.95). The sugar to acid ratio significantly ranging from 3.60 to 5.98, and it was maximum in FA 006 (5.98). Plants of FA 005 contained the maximum amount of ascorbic acid (77.33 mg 100g^-1), while the minimum in FA 010 (53.00 mg 100g^-1).

Location: Fruit Research Farm of Horticulture Research Centre, BARI, Gazipur, Bangladesh

Start Date: 01-08-2009

End Date: 31-05-2011

Program Area: Variety and Species

Commodity: Strawberry

Objectives:

The present study was undertaken to evaluate the collected strawberry genotypes for fruit, yield, yield contributing characters, quality parameters and nutritional components of fruits
To select superior strawberry variety(ies) for for cultivation under Bangladesh

Methodology:

The present study was carried out at the Fruit Research Farm of HRC, BARI, Gazipur, Bangladesh during winter season of 2009-2010 and 2010-2011 to evacuated 13 strawberry genotypes under this study. Healthy and disease free propagules of ‘thirteen strawberry genotypes were considered as treatment and planted in the experimental field the only released strawberry variety namely BARI Strawberry-1 used as check. The experiment was laid out in randomized complete block design with three replications. Beds were raised 30 cm above main field with 50 cm drain in-between 2 beds. Each plot contains double row accommodating 14 plants heaving 50 x 40 cm distance. Daughter plants of strawberry genotypes were planted on 15 October, 2009 and 2010. were removed at every 3 to 4 days intervals in order to make the crown capable to initiate flowers. Straw mulch was applied around the plants as a normal practice in order to conserve soil moisture, decreasing weed and to provide healthy condition for the fruits. Weeds were removed to keep the crop weed free. Irrigation was given at 7 days interval and whenever necessary. All other necessary cultural practices and plant protection measures were followed uniformly for all the plots and treatments during the entire period of experimentation. The following qualitative characters of fruit viz. shape, uniformity, colour, firmness and flavour were recorded by close observation according to the IBPGR descriptors for strawberry. On the other hand, number of fruits plant^-1, fruit weight (g), fruit length (cm), fruit diameter (cm), yield plant^-1 (g), days to harvest, harvest duration, deform fruits (%) and number of achenes fruit^-1were recorded for quantitative fruit characters. Following chemical and nutrient components were recorded viz. reducing sugar, non-reducing sugar, total sugar, total soluble solid (TSS), pH, titratable acidity, TSS to acid ratio, sugar to acid ratio and ascorbic acid contents of fruits.

Achievement/Findings:

The genotypes of strawberries showed remarkable variation in nutrient as well as chemical components of fruit. Considering fruits plant^-1, single fruit weight, yield plant^-1,total soluble solids (TSS), sugars, ascorbic acid, TSS to acid and sugar to acid ratio, the genotypes FA 005, FA 006 and FA 007 were superior to others and found to be promising under Bangladesh condition.
