Abstract/ Executive Summary:

The experiment was carried out at the farm of Central Research Station of the Bangladesh Agricultural Research Institute. Gazipur during 1991-92 with 38 local and exotic genotypes to characterize morphological, reproductive and agronomic characters. A wide range of variations were observed among the germplasms with respect to various parameters. This characterization and documentation will help the breeder to select the desirable parents for the improvement of chilli.

Keywords: Chilli, Local and exotic genotypes,Characterization

Location: Central Research Station of the Bangladesh Agricultural Research Institute, Gazipur.

Start Date: 24-10-1991

End Date: 00-05-1992

Program Area: Variety and Species

Commodity: Chilli

Objectives:

To characterize morphological, reproductive and agronomic characters.

Methodology:

The experiment was conducted at the farm of Central Research Station of the Bangladesh Agricultural Research Institute, Gazipur during the period from October 1991 to May 1992. There were 38 lines of chilli collected from home and abroad. Out of the 38 germplasms, 14 were collected from different regions of the country and the rest from India, Thailand, Indonesia, Malaysia, Taiwan, Srilanka, Korea, Brazil and Nigeria. Seeds were sown in seed bed on 24 October 1991 and transplanted on 8 December 1991. The experiment was non-replicated. Unit plot size was 3m x 1.35m. Spacing between plants was 40 cm, while row to row distance was 45 cm. The crop was fertilized with cowdung @ 5 tons per hectare, and N, P₂0₅ and K₂0 @ 120,96 and 90 kg per hectare, respectively. The entire quantity of cowdung and TSP were applied during final land preparation. Urea and MP were applied in four equal splits 20,50,80 and 110 days after transplanting. Irrigation along with other intercultural operations were done as and when needed. Harvesting was started on 28 February and continued up to 19 May 1992. Data were recorded on plant type, plant vigour, foliage coverage, stem hair, corolla colour, number of flowers per node, fruit pungency, weight of individual fruit; fruit length and width. Plant and flower characters were studied as per method followed by the Asian Vegetable Research and Development Centre (AVRDC), Taiwan. Organoleptic taste by a panel of five judges was done for evaluating fruit pungency.
