Abstract/ Executive Summary:

A study on the performance of six heliconia germplasm was conducted at Floriculture Field of HRC, BARI, Gazipur during 2013-2014. Wide range of variability was observed among the genotypes under study in respect of flowering behaviour and leaf colour. Among the genotypes, H-001, H-003, H-004, H-005 and H-006 produced erect type flower while H-002 had drooping type. As regards to the colour of flower, the observed genotypes showed remarkable variation such as orange, reddish yellow, reddish orange, yellow, pinkish orange and red. Variation was also observed in case of leaf colour . Duration of flowering varied from March to July. H-004 was best for the production of maximum number of shoots (12) while the minimum (4) was produced by H-006. The maximum number of bracts/shoot (10) was observed in H-002. The longest bract (16.0 cm) was observed in H-004, which is superior to other genotypes. H-002 produced the longest flower stalk (65.0 cm) closely followed by H-004 (60.0 cm).The shortest stalk length (48.0 cm) was observed in H-003. Among the genotypes, H-002 produced the maximum number of flower (30) per shoot while H-003 and H-006 had the minimum (20). Variation was observed within the genotypes in respect of flowering area. H-002 attained maximum flowering area (21.5 cm) while the minimum (10.7 cm) was recorded in the genotype H-003. Among the genotypes, vase life varied from 6 to 10 days. The maximum vase life (10 days) was recorded in H-004 while the minimum (6 days) in H-003.

Keywords: Heliconia, Cut flowers, Qualitative, Quantitative characters

Location: Floriculture Field of HRC, BARI, Gazipur

Start Date: 00-00-2013

End Date: 00-00-2014

Program Area: Variety and Species

Commodity: Heliconia

Objectives:

To find out the best line (s) for cut flower.

Methodology:

The experimental material comprised of six genotypes, H-001, H-002, H-003, H-004, H-005 and H-006. They were grown during summer season of 2013 at the Floriculture Field of HRC, BARI. All genotypes were collected from different nurseries. Accession numbers were given to each entry. Before planting, pit was prepared properly. Manure and fertilizer were applied according to dose found in literature. Watering and other intercultural operations were done as and when necessary. Data were recorded on 5 randomly selected plants for plant height, shoots/plant, bract/shoot, bract length, stalk length, flowers/shoot, flowering area, vase life etc. The recorded data were statistically analyzed and treatment means were separated by DMRT.
