Benefits of technology

[0009] The present invention uses a novel diploid watermelon to improve current methods of commercial production of seedless watermelon and to increase seedless watermelon yield. According to the invention, there is provided a novel enhanced, pollenizer diploid watermelon (hereinafter referred to as “enhanced pollenizer”) and method for pollinating seedless watermelon plants. The present invention includes an enhanced pollenizer comprising, at

[0055] The following Examples are provided to illustrate the present invention, and should not be construed as limiting thereof.

[0056] Example 1: Triploid watermelon plants are planted in parallel rows 7 feet apart and 3 feet apart within each row. However, the enhanced diploid watermelon plants are planted in a narrow row 3.5’ wide (1 / 2 the width of the triploid rows) between every second and third triploid row. For example, rows A and B are two consecutive rows of triploids, each 7-foot wide. Row C is a diploid row that is 3.5 feet wide. Row D and E are the following two 7 foot wide rows of triploids, followed by the 3.5-foot wide row F of diploid plants. This pattern is repeated across the width of the field. Because the diploid row is narrower according to the method of the invention, the distance between rows B and D is 10.5 feet instead of the traditional distance of 14 feet. Using this ratio of 1 pollenizer row for every 2 triploid rows (1:2), 33.3% of the field would n...

Abstract

Abstract of the Disclosure
An enhanced, diploid pollenizer watermelon plant and method used to maximize the yield of triploid seedless watermelons per area. The enhanced pollenizer watermelon plant of the invention is either a hybrid variety, an open-pollinated variety or a synthetic variety, that exhibits the characteristics of small leaves and fruit with a brittle rind that splits when the fruit is overripe or breaks when relatively small physical forces are applied. The watermelon plant of the invention is also preferably characterized by extended flowering duration, thereby increasing the number of triploid watermelon flowers that are pollinated and set fruit. The method for producing a seedless watermelon fruit, includes the steps of providing a pollenizer diploid watermelon plant, extending the duration of flowering of the pollenizer plant while reducing the number of such plants needed to pollenize the same number of triploid watermelon plants, and maximizing dispersal of the pollenizer watermelon plant throughout the field of triploid watermelon plants.

Description

Detailed Description of the InventionCROSS-REFERENCE TO RELATED APPLICATIONS[0001] This application is a continuation-in-part of U.S. Application No. 10 / 091,154, filed March 5, 2002. The aforementioned application is incorporated herein by reference in its entirety.FIELD OF THE INVENTION[0002] This invention is in the field of watermelon breeding, specifically relating to diploid watermelons used to pollinate triploid watermelon plants for the commercial production of seedless watermelon fruit, and includes a novel method for the production of triploid watermelon fruit.BACKGROUND OF THE INVENTION[0003] Watermelon is an important horticultural crop that accounts for 2% of the world area devoted to vegetable crops. There were 6,024,000 acres of watermelon grown in the world and 187,000 acres of watermelons grown in the United States in 1997 (FAO Production Yearbook 51, 1998). The estimated annual world watermelon value exceeded $7.6 billion when using the United States average price ...
