| Abstract: | 【Objective】A new tetraploid few-seed watermelon variety was bred suitable for open field and greenhouse to diversify watermelon varieties for enhancing competitiveness of Guangxi watermelon industry. 【Method】In2009, tetraploid watermelon 403（female parent） and tetraploid watermelon JL（male parent） produced a new hybrid tetraploid watermelon Xinggui 6, which was tested for two consecutive years in open field（2009-2010） and greenhouse（2011-2012）. 【Result】The entire growth period of Xinggui 6 was 90-100 d in spring and 65-80 d in autumn. Its fruit maturity period was 29-35 d. Its single fruit weight was 3.5-4.5 kg and the fruit was round, dark green and bright covered by green stripes. The rind thickness was 1.0-1.2 cm. Xinggui 6 was resistant in storage and transportation. The pulp was bright red and smooth with less fiber, less seed and more juice. Xinggui 6 was firm, fresh and sweet with good quality and its sugar content was 11.5% in the center. In 2009-2010, its average yield was 38081.3 and 34602.8kg/ha, up by 15.6% and 13.7% over the control. In 2011-2012, its average yield was 66577.5 and 63169.5 kg/ha,up by 18.1% and 15.0% over the control. In 2012, the average yield in Guangxi regional trial was 34182.0 kg/ha, up by 10.8%. In 2010-2012, the average yield in open field was 32550.0-36585.0 kg/ha, up by 10.6%-15.5% and the average yield in greenhouse was 60178.5-63168.0 kg/ha, up by 12.6%-15.2%. 【Conclusion】This new hybrid tetraploid watermelon Xinggui 6, appropriate for open field and greenhouse, should be extended in watermelon planting areas of Guangxi. |
