In the watermelon nursery bed, it is often found that some seedlings are different, some of the large seed varieties are particularly wang wang seedlings, and their stems and leaves are stout and their growth is very prosperous. Some weak seedlings in the small seed varieties, the stems and leaves are thin and the growth is very poor. These special seedlings spread in the middle of normal seedlings, and the proportion is generally 2% to 5%. This phenomenon occurs mainly due to the existence of 5% of self-inflicted seeds in the hybrid seed. Since the watermelon varieties currently used in production are basically hybrids, it is difficult for hybrid seeds to achieve a 100% hybridization rate, and national standards permit that 2% to 5% of inbred seeds are allowed. Inbred seed germination grows into self-injected seedlings. Self-seedling seedlings transplanted into Daejeon are parental melons. The parental melon has no hybrid superiority, and its traits, such as size, quality, commercial character, and disease resistance, have serious disadvantages compared with the normal hybrid melon. However, the inbred seeds in the hybrid seed are still not distinguishable, and only after seedling emergence can they be distinguished. Therefore, they must be excluded from the seedbed and before planting. It has become a common practice for farmers to keep their seedlings when they are transplanted. The self-inflicted seedlings in small seed varieties can be removed due to their weakness. However, the Tung seedlings in large seed varieties are often mistaken for good seedlings, and therefore, they should be removed when planting.
