Abstract/ Executive Summary:

An experiment was conducted to classify and evaluate the available gerbera cultivars (Gerbera jamesonii, Hook) in Bangladesh. We used twenty four gerbera cultivars and those were coded from V1-V24. It was found that V8, V9. V10, V11, V12, V15, V16, V19, V20, V21, V22, V23 and V24 were performed as best in terms of different growth, yield also the quality contributing characters. These cultivars (V8-V12, V15, V16, V19-V24) also provided plenty of variation for leaf area (ranges from 215.7 cm² to 231.1 cm²). We found that flower head diameter was>10.0 cm (except V8), peduncle diameter was >8.0 mm, standard peduncle length >30.0 cm and petal thickness >0.39 mm (except V8) for these the best performing cultivars (V8-V12, V15, V16, V19-V24). On the other hand we had classified these 24 gerbera cultivars into 5 classes according to their blooming pattern. The five classes are singles (V1, V4, V14)doubles (duplex) (V5,V12, V18, V21, V22, V23, V24), crested doubles (V2, V3, V6, V7, V8, V10, V11, V15, V16, V19, V20), full crested doubles (V9) and quilled crested doubles (spider) (V13, V17).

Program Area: Socio-economic and Policy

Commodity: Gerbera

Objectives:

Present investigation was carried out with a view to classify and evaluate the performance of the gerbera cultivars available in Bangladesh.

Methodology:

This experiment was conducted at Rooftop Garden under 2abiotech, Department of Horticulture, Sher-e-Bangla Agricultural University, Bangladesh during the months of December 2012 to July 2013 to classify and evaluation of gerbera cultivars. The experiment was laid out in completely randomized design (CRD) with three replications. Same aged micro propagated seedlings were collected from Krishibid Upokoron Nursery, Sher-e-Bangla Nagar, Dhaka-1207 and these were used in the experiment. Soil and cow-dung (1:1) were mixed and pots were filled 7 days before transplanting. We applied cowdung @ 1 tha^-1, cocodust @ 2000kg ha^-1, urea 350@ kg ha^-1, TSP 250@ kg ha^-1, MOP 300@ kg ha^-1, zipsum165 @ kg ha^-1, boric acid 12 @ kg ha^-1 and zinc oxide 4 @ kg ha^-1in soil of well ploughed field (BARI, 2011). Then we filled the experimental pot with the fertilized field soil. We used 24 cultivars for this experiment and coded these from V1 to V24. Data were collected on leaves number, plant height, leaf area, chlorophyll content, number of flower, flower head diameter, peduncle diameter, peduncle length and petal thickness from each pot within the period. Leaves number, plant height, leaf area and chlorophyll content were measured at 100 days after transplanting. Leaf area was measured by non-destructive method using CL-202 Leaf Area Meter (USA). SPAD-502 Chlorophyll Meter was used for measuring chlorophyll content in percentage (%). Peduncle diameter and petal thickness were measured by using Digital Caliper-515 (DC-515). All parameters were statistically analyzed by using MSTAT-C program. Mean for all the treatments was calculated, analysis of variance for each of the characters was performed by F-test and difference between treatments was evaluated by Least Significant Difference (LSD) at 5% level of significance (Gomez and Gomez 1984). We employed SPSS (Statistical Package for the Social Sciences) to build the Dendogram for groping the variants according to the morphological and yield contributing characters.

Achievement/Findings:

V1, V4, V14 (single), V5, V12, V18, V21, V22, V23, V24 (doubles/duplex), V2, V3, V6, V7, V8, V10, V11, V15, V16, V19, V20 (crested doubles), V9 (full crested doubles) and V13, V17 (quilled crested doubles or spider) cultivars were classified into five different groups. Further classification study of these flower with their leaf shape is suggested. From the above result and discussion it can be stated that V8, V9. V10, V11, V12, V15, V16, V19, V20, V21, V22, V23 and V24 can be suggested to cultivate commercially for higher market value.
