Abstract/ Executive Summary:

A field experiment was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka with a view to study character association and path analysis in six strawberry genotypes. The trial was laid out in a Randomized Complete Block Design with three replications. Data on crown height, number of flower buds per plant, number of flowers per plant, number of fruits per plant, length and breadth of fruit and fruit yield per plant were collected. All the characters showed significant correlation with fruit yield. Path analysis revealed that crown height, number of flowers per plant and length of fruit had the positive direct effect on yield per plant. Number of flower buds per plant, number of fruits per plant and breadth of fruit had negative direct effect on yield per plant.

Keywords: Correlation, Path analysis, Strawberry

Location: Horticulture Farm, Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka

Start Date: 00-11-2009

End Date: 00-03-2010

Program Area: Variety and Species

Commodity: Strawberry

Objectives:

To examine the relationship among yield contributing characters and yield of strawberry genotypes.

Methodology:

The experiment was conducted in the Horticulture Farm, Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka, during November, 2009 to March 2010. The location of the site is 23⁰74' N latitude and 90⁰35' E longitude with an elevation of 8.2 m from sea level. This was a single factor experiment with six (6) strawberry germplasm viz. FA 01, FA 02, FA 03, FA 04, FA 05 and FA 06 collected and multiplied in Horticulture farm, Sher-e-Bangla Agricultural University. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The data were collected from randomly selected 3 plants from each treatment. The data were recorded on different characters such as crown height of strawberry, number of flower buds per plant, number of flowers per plant, number of fruits per plant, length of fruit (mm), breadth of fruit (mm), weight of individual fruit, yield per plant (g) and yield per hectare.

Achievement/Findings:

Correlation and path coefficient analysis results revealed that in most of the cases correlation coefficient values were higher indicating strong inherent relationship among the traits. Path analysis showed importance of the characters such as crown height, number of flowers per plant and fruit length and emphasis should be given on these characters for effective selection
