Planting in summer and autumn, harvesting in September, and ripening 25 days after fruit setting.

Melon is small, the largest is only 3kg, the sugar content is high and uniform, and it melts in the mouth. This yellow watermelon takes only 33 days from fruit setting to maturity, and it can be harvested twice a year with a yield of 3000 kilograms per mu.

Pepkino

Pepkino is a mini watermelon and a wild plant in South America. The shape is similar to sweet potato, but "Pepkino" is only 3 cm long and 2 cm in diameter. Although the appearance is the same as that of ordinary watermelon, the pulp of "Pepkino" is turquoise and the root is stem-shaped.

"Pepkino" has two colors and shapes, one is light green ribbon pattern, and the melon and fruit are usually oval; The other is dark green and yellow, and melons and fruits are generally round.

White pulp

Watermelon with white flesh should be ripe and edible, but the variety of watermelon is still uncertain.

Heart-shaped watermelon

20 14 Kimura, a farmer in Kumamoto, Japan, overcame many difficulties through long-term experiments and created his own heart-shaped watermelon. It is said that his inspiration came from a neighbor's joke. Rocket News reported: "This heart-shaped watermelon made a sacrifice in viscosity to make the juice sweeter. Once you wolf down this heart-shaped watermelon, you will leave some soft and sweet flesh on your lips.

Square watermelon

Square watermelons were planted in Japan, initially just to facilitate storage and save space. Square watermelons sold in supermarkets in Hangzhou can be kept for half a year at room temperature. Watermelon varieties can be divided into three categories: early maturity varieties, middle maturity varieties and late maturity varieties.

1, an early-maturing variety takes 90-90 days from sowing to harvesting, and melons mature quickly, taking 25-30 days from female flower to maturity, which is suitable for close planting. Excellent varieties include Xin Jing, Zhengza, Zaohua and other small melon varieties.

2. Mid-mature varieties, it takes 90- 100 days from sowing to harvesting in the north, melon matures later, and it takes 30-40 days for female flowers to bloom and mature, with large plant type and strong growth. This kind of melon is big and thick, which is resistant to transportation and storage, such as Xinong R. ..

3. Late-maturing varieties, such as Kouyuu No.2, need 100- 120 days from sowing to harvest in the north, with less soft cultivation, large melon and good storage resistance. According to the purpose

Watermelon can be divided into fresh watermelon and seed watermelon. The selected watermelon varieties are mostly fresh watermelons, which are the main types of watermelon cultivation and the varieties with the highest utilization rate of heterosis. Seed melon has strong adaptability, high seed setting rate of lateral vines and extensive management, and its seed selection is the same as that of fresh watermelon. Inner Mongolia, Gansu, Xinzu and other provinces are the main producing areas of large melon seeds in China, mainly conventional varieties. Gansu has cultivated hybrid varieties. There are diploid, tetraploid seedless watermelon and triploid seedless watermelon.

1. The most common method of doubling diploid watermelon is to treat watermelon seeds with colchicine to make them become newly unearthed seedlings and obtain tetraploid.

2. Tetraploid watermelon is obtained by artificially inducing diploid watermelon to achieve chromosome doubling. Generally, it is only used as a parent (female parent) when triploid seedless watermelon is cultivated, and it is not used for cultivation.

3. Triploid watermelon takes diploid watermelon as the male parent. The tetraploid watermelon obtained by crossing with the female parent has the characteristics of high quality, high yield and seedless, and f 1 generation has excellent varieties such as black rice and Xin No.1.
