Abstract/ Executive Summary:

Fifteen strawberry germplasm were evaluated for different qualitative and quantitative characters. The germplasm showed variation for majority of the studied traits. Plant height during peak harvest ranged from 14.67 to 25.00 cm and FA 007 exhibited the tallest plants. The maximum number of leaves plant^-1 was produced by FA 006 (46.67). The maximum number of runners plant^-1 was obtained in FA 003 (68.67), while the highest number of crown plant^-1 was found in FA 007 (15.33). Days for flowering varied from 48.33 to 102.30 among the germplasm and FA 008 required minimum (48.33) days for flowering. The germplasm FA 004 produced the highest number of flower trusses (35.50 plant^-1) while it was the lowest in FA 010 (5.00 plant^-1). The number of flowers plant^-1was found maximum in FA 003 (168.00 plant^-1) and minimum in FA 010 (40.00 plant^-1). Among the germplasm pollen viability varied significantly and maximum viable pollen was recorded in FA 010 (84%), while it was lowest in FA 004 (12.00%). Strawberry-1 exhibited the highest fruit set (86%), while FA 013 (39 %) showed the lowest. Among the germplasm the highest yield plant^-1 was recorded from FA 005 (737.70 g) followed by FA 006 (702.30 g) and was significantly higher than others while the lowest yield plant^-1 was recorded from FA 013 (52.00 g).

End Date: 00-05-2010

Program Area: Variety and Species

Commodity: Strawberry

Objectives:

The present study was undertaken to characterize the collected strawberry germplasm for morphological characters and
To select superior strawberry germplasm on the basis of morphological characters for release as a varieties.

Methodology:

This study was conducted at the HRC, BARI, Gazipur, Bangladesh during August 2008 to May 2010. Healthy and disease free daughter plants of 15 strawberry germplasm were considered as treatments and planted in the experimental field where BARI Strawberry-1 was used as check. The experiment was laid out in a randomized complete block design with three replications. The unit plot size was 100 x 280 cm and the plants were spaced 50 x 40 cm on open beds. Beds were raised 30 cm above main field with 50 cm drain in-between 2 beds. Daughter plants of strawberry germplasm were planted in September 15, 2008 and 2009. Runners 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 avoid contact of the fruits with soil for reduction of rot caused by soil microbes. Weeds were removed whenever necessary to keep the crop weed free. Irrigation was given whenever necessary to keep soil moisture available in the field for better plant growth. All other necessary cultural practices and plant protection measures were followed uniformly for all the plots and treatments during the entire period of experimentation. Following vegetative characters viz. growth habit, plant vigor, foliage density, foliage color of strawberry plants and position of inflorescence were recorded by close observation according to the descriptor developed by IBPGR. On the other hand, plant height (cm), plant spread (cm), leaves plant^-1, runners plant^-1, crowns plant^-1, days to flowering, flower trusses plant^-1, flowers plant^-1, size of flower (cm), disk size of flower (receptacle) (cm), pollen viability (%) and percent fruit set were recorded for quantitative growth characters of strawberry plants and yield plant^-1 (g). Two year’s data of different quantitative parameters were pooled and analyzed, following RCB design using MSTAT-C. The mean comparison was done following the Duncan’s Multiple Range Test (DMRT).

Achievement/Findings:

The genotypes of strawberries showed variation in morphological as well as quantitative traits. On the basis of physico-morphological characters, it was concluded that genotype FA 006 and FA 007 were identical with FA 016 and FA 017, respectively. On the other hand, based on poor pollen viability as well as poor fruit set the genotypes FA 003 and FA 004 were discarded. Finally the genotypes FA 005, FA 006, FA 007, FA 008 and BARI Strawberry-1 were selected for further investigation.
