This study was conducted to investigate days after anthesis (DAA) and fruit after-ripening period (FAP) for seed-harvesting of high quality watermelon seeds. Fruit weight and number of seed per fruit increased according to DAA, while those did not significant about FAP. Ratio of cotyledon at whole seed was higher about 2 to 4% compared to seed coat irrespective of DAA and FAP. Germinability of watermelon was not a significant effect by DAA, however, it had differences by FAP. Percent of germination (PB) was below 50%, when 30 days maturated fruits after anthesis was omitted ripening, while PB was increased to 92% by ripening. In addition, seeds at DAA 40 and FAP 20 were higher general seedling vigors (hypocotyl length, diameter etc.) in BP test. Results indicated that considering seed productivity, it had maximized seed viability at DAA 40 and FAP 20.
