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. In one embodiment, the watermelon plant of the invention is also 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 pollinate the same number of triploid watermelon plants, and maximizing dispersal of the pollenizer watermelon plant throughout the field of triploid watermelon plants.

The invention discloses a method for identifying S genotype of an apple and a special reagent kit thereof. The method uses the genomic DNA of an apple variety to be detected as a template and amplification is carried out by the use of primer pairs for identifying the S genotype of the apple variety so as to determine the S genotype of the apple variety to be detected according to the amplification result. By the method, the selfed incompatible S genotype of the apple variety can be fast identified, and pollenizers can be selected through the S genotype thereof. Therefore, the method has important application value on apple planting and hybridization research.

A method for increasing production of hybrid seed of bee-pollinated crops, such as alfalfa and soybean at predetermined hybridity levels. Hybrid seed is produced using female and pollenizer plants at a selected ratio of female plants to pollenizer plants. The female plants and the pollenizer plants are intermingled in the hybrid seed production field. Prediction of percentage of hybridity at various female to pollenizer ratios allows for selection of a ratio of female plants to pollenizer plants to provide seed at a test percentage of hybridity. The percentage of hybridity may be increased post-harvest by employing techniques using seed properties such as size differential, color or density to remove a higher percentage of non-hybrid seed. The hybrid seed product is maximized at various hybridity levels. Planting according to subrows allows for separate harvesting of intermingled crops. Testing the hybrid seed product provides verification of percentage of hybridity.

The application relates to the field of plant breeding, in particular watermelon breeding. Provided are diploid watermelon plants (and seeds from which these plants can be grown) which produce small, diploid, red watermelon fruits. Also provided are small, diploid watermelon fruits having an average weight of less than 1.8 kg.

The invention provides containers comprising at least one or at least two seedlings of at least one seedless watermelon variety and at least one seedling of a seeded pollenizer watermelon variety. The present invention further provides methods for producing watermelon fruit, optionally over an extended season, comprising planting together in a container at least one seedling of a seedless watermelon variety and at least one seedling of a seeded pollenizer watermelon variety, wherein the at least one seedling of a seeded pollenizer watermelon variety produces male flowers in sufficient time to pollenize female flowers of the at least one seedling of a seedless watermelon variety.

The invention discloses a kiwi berry artificial pollination method. The method comprises the following steps: preparing a pollenizer; before florescence, controlling diseases such as blossom blight, ulcer, gray mold, and the like; wherein during the florescence, no pesticide or herbicide is used, and broad irrigation is maximally avoided; arranging a rainproof facility, which is started before florescence/pollination and is closed at least two hours after pollination; and carrying out artificial pollination. The pollination time is chosen according to the species of kiwi berry; for the early maturing variety, pollination is carried out on the 2nd-4th days to achieve an optimal effect; for the medium-late maturing variety, pollination is carried out on the 3rd-5th days to achieve an optimaleffect; pollination is carried out at 8-11 am and 2-4 pm, at a temperature of 26 to 30 DEG C under a relative humidity of 68-78%; and the pollination method comprises artificial pollination, airbag type pollination, and needle pollination. The artificial pollination is carried out at optimal time and environment to increase the fruit setting rate; the quality, output, and appearance of products are all improved, the cost is saved, and the method is simple to teach.

The invention relates to a diploid watermelon having fruit with approximately ⅓ lower sugar content than common watermelons found in the market place, and plant characteristics favorable for use as a pollenizer for commercial production of seedless watermelons. In addition to reduced sugar, fruit characteristics of the invention include a tough rind, firm flesh, distinct rind color, and small fruit. The watermelon plant of the invention has the characteristics of extended flowering duration, thin leaves, long sprawling vines, and resistance to Fusarium Wilt caused by Fusarium oxysporum race 1. The invention combining the above mentioned fruit and plant characteristics can serve the dual purpose of producing reduced sugar watermelon fruit, and pollinating seedless watermelons. This will, in effect, produce reduced sugar watermelons which are beneficial for consumers with type 2 diabetes, as a byproduct of commercial seedless watermelon production making the product more economically feasible.
