DEVELOPMENT OF AN OPEN POLLINATED PUMPKIN VARIETY (CES STARZ) WITH UNIFORM SHAPE, SKIN COLOUR AND QUALITY CHARACTERS FOR THE EXPORT MARKET

Pumpkin is one of the crops grown in Trinidad and Tobago with a competitive advantage in the export market. A sector analysis conducted in 2005 identified the instability of cultivars leading to irregular shapes and sizes as one of the major weakness affecting the export market. A survey of producers/exporters revealed that the main characteristics required for export were smooth, cream/green coloured skin with thick, yellow/orange, sweet flesh. A number of fruits were collected and evaluated for the desired physical and quality characters. A breeding programme was developed using a Phenotypic Assortive Mating Design and Mass Selection to improve the uniformity of the varieties grown in Trinidad and Tobago. The characterization/evaluation data collected for this project included the following: skin colour (primary, secondary), flesh thickness, colour, flavour, moisture, texture, fruit shape, weight, fruit skin texture, diameter, length, skin hardness, cavity diameter, number of seeds/fruit, flesh moisture, total soluble solids and % dry matter. After six generations of breeding and selection the variety CES STARZ was developed with 79.7% uniformity with respect to fruit shape, skin and flesh colour in addition to improvement in sweetness and dryness.
