Abstract/ Executive Summary:

Four hybrid clones were evaluated at Joydebpur, Jamal pur, Bogra, Jessore & Pahartali against different parameters. Among the five locations, the highest mean of yield was obtained by Hnl08 (30.84 t/ha), followed by Hy'08 (30.81 t/ha) and the lowest yield was found in BARl SP-8(24.67 t/ha). Considering dry yield, marketable yield and other factors three hybrid clones namely, H/08, H/08 and H4/08 were selected for next year evaluation

Keywords: Sweet potato clones,Hybridization

Location: Joydebpur, Jamal pur, Bogra, Jessore & Pahartali

Start Date: 00-00-2013

End Date: 00-00-2014

Program Area: Variety and Species

Commodity: Potato

Objectives:

To find out suitable sweet potato clones, derived from hybridization

Methodology:

The experiment was conducted at Joydebpur, Jamal pur, Bogra, Jessore and Pahartali during 2013-2014.Four hybrid clones which were tested promising and selected from last year trial were included the study with BARI SP-8 & BARI SP-9 as checks. Vines were planted on 13 th November, 2013 the field having a plot size 3.0 x 3.0 m and replicated thrice following RCBD. The crop was '!ized with recommended doses. Crop was harvested on lst April, 2014. Data on phenotypic cters yield and yield contributing characters were recorded from 10 randomly selected plants.

Achievement/Findings:

There were significant variations among the clones in respect of all characters studied. The skin colour of the tuber varied light yellow to Red and the flesh colour of the tuber varied light yellow to deep orange. The length of main vine among the clones varied 104.S2 ern (Hi08) to 120.91 em (BARI SP-9). The highest length of tuber was found in H4/OS (14.02 em) and diameter of tuber was highest in H5/0S (4.15 ern). The number of tuber per plant ranged 3.85 to 6.17. The fresh weight of tubers per plant was the highest in Hz/OS (59S.71 g), followed by H5/0S (591.52 gl, and the lowest (456.77 g) fresh weight of tuber per plant obtained by BARI .
