What are the types of watermelon? What are the types of watermelon?

Watermelon is a fruit that we all like to eat very much. So what are the types of watermelon? You may not know the types of watermelon very well when buying it, so today I will give you a detailed analysis:

1. Maturity

Watermelon varieties can be divided into three categories: early-maturing varieties, mid-maturing varieties and late-maturing varieties.

1. Early-maturing varieties take 90-90 days from sowing to harvesting, and the melons mature quickly, taking 25-30 days from the opening of the female flowers to maturity. The plant yield is small and suitable for dense planting. Excellent varieties include Jingxin, Zhengza, Zaohua and other small-melon varieties.

2. Mid-ripening varieties: In the north, it takes 90-100 days from sowing to harvesting. The melons mature a little later, and it takes 30-40 days from the opening of the female flowers to maturity. The plant is large and has strong growth. The melons of this type of variety are large, thick-skinned, and more resistant to transportation and storage, such as Xinong R.

3. Late-maturing varieties in the north require 100-120 days from sowing to harvesting, with less soft cultivation, larger melons, and better storage resistance, such as Hongyou No. 2.

(ii) According to the purpose

Watermelon can be divided into fresh-eating watermelon and seed-eating watermelon. Currently, most of the watermelon varieties selected and bred are fresh-eating watermelons, which are the main type of watermelon cultivation and have the highest degree of utilization of hybrid vigor among watermelon varieties. Seed-eating watermelons have strong adaptability, high side vine fruiting rate, and relatively extensive management. The selection of watermelons is the same as that of fresh-eating watermelons. Inner Mongolia, Gansu, Xinzu and other provinces and regions are the main production areas of large-leaf melon seeds in China. They are mainly conventional varieties. Gansu has cultivated hybrid varieties.

(III) Types of watermelon based on chromosomes:

Diploid, tetraploid seeded watermelon and triploid seedless watermelon. Among them, tetraploid watermelon is obtained by artificially inducing mutation of diploid watermelon to achieve chromosome doubling. It is generally only used as a parent (female parent) when cultivating triploid seedless watermelon, and is not used for cultivation. The most commonly used method for doubling diploid watermelon is to treat watermelon seeds with colchicine into newly unearthed seedlings to obtain tetraploid. Triploid watermelon is obtained by using diploid watermelon as the male parent. Tetraploid watermelon is obtained by hybridization as the female parent, and has the characteristics of good quality, highest yield, and seedless. Excellent varieties in F1 include Heimi and Xin No. 1.
