Abstract/ Executive Summary:

The experiment was conducted at the Horticulture Field Laboratory of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during November 2005 to July 2006. Twelve genotypes of Bangladhonia ( E. foetidum L.) were collected from different parts of Bangladesh and evaluated them to analyze the variations. Most of the yield attributing characters and individual plant performances exhibited insignificant differences among the genotypes. All the genotype had the similar plant and leaf size, number of leaves/plant, weight of leaves/plant, flowering behavior, yields and other qualitative characters. Greater positive correlation was observed between plant populations with yield performances. The symmetric performance indicted that all the genotype belongs from the same species of E. foetidum L. and there was no major phenotypic or genotypic variation among them.

Start Date: 00-11-2005

End Date: 00-07-2006

Program Area: Variety and Species

Commodity: Coriander

Objectives:

To collect the genotype from different places of Bangladesh and to evaluate them in the field under similar condition and analyze the useful character.

Methodology:

The experiment was conducted at the Horticulture Field Laboratory of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during November 2005 to July 2006. The location of the experimental site was on 24⁰09^/ North latitude and 90⁰26^/ E longitude with an elevation of 8.50 m from the sea level (Anon., 1989). The experiment al field belongs to the ‘Shallow red brown terrace’ soil of Salna series under Madhupur tract of AEZ -28. The pH of the experimental soil was 5.9. The experiment was laid out in a randomized complete block (RCB) design having twelve Treatment (12 accessions) with three replications. The unit plot size was 3m×1m. Twelve genotypes were collected from Rangamati, Bandarban and Khagrachari districts and one was collected from Gazipur.The land was carefully prepared by ploughing and cross ploughing followed by laddering because Bangladhonia seeds ar e very small and responsive to the physical condition of the beds (Moni ruzzaman, 2000). Manures and fertilizers were applied @ Cowdung 15 tons, urea 350 kg, TSP 150 kg, and MoP 200 kg per hectare. The entire amount of cowdung and TSP with one fourth of urea and MoP were applied during final land preparation. The rest of the urea and MoP were applied in three equal installments at 45, 75 and 105 days after sowing of seeds (Islam et al ., 2003). Seeds of 12 Bangladhonia genotypes were sown @ 40 kg/ha ((12g/plot) by broadcasting on 08 December 2005. After sowing the plots were covered with dry rice straw to make the soil uniformly moist for better germination. After sowing, black mosquito (nylon) nets (2 mm loop) was hanged at 1.5 meter height over the experimental plots to maintain approximately 50% photosynthetically active radiation (PAR), w ith the help of GI wire and bamboo poles in order to ensure soft, lengthy and succulent leaves (Moniruzzaman, 2006). Straw mulch was removed when germination started and weeding was done carefully. Weeding was done, frequently after germination. Sprinkler irrigation was given twice in a week and flood irrigation was given to the plants after each top dressing of urea and MoP. Thinning was done at the time of harvest when longer (leaf) plants were picked up for marketing. A number of flower stalks were produced and it was counted and broken so that more leaves could be produced. For the control of damping off and leaf blight, Ridomil gold (0.2%) was sprayed three times at 10 days interval. As there was no insect pest, no insecticide was applied. Harvesting was done from May 25 to July 25 with an interval of 20 days when the leaves becamel most succulent. Data recorded on days to seed emergence, seedlings population/m 2 , plant height, leaves per plant, length of leaf (cm), width of leaf (cm), fresh plant weight, days to flower stalk emergence, harvested plants/m 2 , thousand seed weight, days to first flowering, flower stalk number. The percentage of flowering and dry matter percentage was calculated. Qualitative and morphological data on leaf , stem, root and flower stalk were recorded according to botanical descriptor tors (Bandre and Pande, 1999). All the data were compiled properly and analyzed statistically using MS-Excel and SPSS Program. Descriptive analysis and Hierarchical cluster analysis using different yield attributing and other characters were conducted using SPSS and Genstat program, respectively.

Achievement/Findings:

All the genotype had the similar plant and leaf size, number of leaves/plant, weight of leaves/plant, flowering behavior, yields and other qualitative characters. Greater positive correlation was observed between plant populations with yield performances. The symmetric performance indicted that all the genotype belongs from the same species of E. foetidum L. and there was no major phenotypic or genotypic variation among them.
