A kind of method for improving the yield of thick-skinned muskmelon hybrid seed production

Abstract

The invention relates to the method for improving the yield of cucumis melon hybrid seed production and belongs to the technical field of plant breeding. The method is characterized by comprising the steps that when a main vine grows to the length of about 20 cm, four to five main leaves are kept for pinching; four to five side vines are kept, cross pollination is carried out on two to six female flowers of each side vine, and cross pollination is carried out once at nine o'clock to ten o'clock in the morning and once at four o'clock to six o'clock in the afternoon; two to three fruits are kept for each side vine, and when the diameter of each fruit is 10-16 cm, a soft towel disinfected through 75% of ethyl alcohol is used for wiping off the epidermal hair of the young fruits; one to three days after wiping is carried out, 0.1% of Ca (NO3)2 is sprayed on plants and fruit surfaces one to two times in the morning on a sunny day, six to ten fruits are kept for a single plant, and seeds are harvested after the fruits are mature. The method is simple and easy to implement, capable of greatly improving the yield of the cucumis melon hybrid seed production and saving the land cost, and suitable for large-area seed production of cucumis melons.

Description

technical field [0001] The invention belongs to the technical field of plant breeding, and in particular relates to a method for improving the yield of thick-skinned muskmelon hybrid seed production. Background technique [0002] Melon (Cucumismelo L.), also known as muskmelon, fruit melon, sweet melon, etc., is an annual vine herb of Cucurbitaceae Melon. According to statistics, the sown area of ​​melon in my country is about 8 million mu, with an annual output value of more than 4 billion yuan, ranking first in the world. In 2012, the planting area of ​​melons in Jiangsu Province was 27,500 hectares, and the demand for melon seeds was more than 8,000‐10,000 kg. At present, the thick-skinned muskmelon varieties are mainly hybrid varieties, and the wide application of new thick-skinned muskmelon varieties with hybrid advantages has driven the rapid development of the muskmelon industry. [0003] At present, the yield of melon hybrid seed production is low, the quality and ...

AI Technical Summary

Problems solved by technology

[0003] At present, the yield of melon hybrid seed production is low, the quality and purity of seeds are difficult to control, and the production cost is high, which restricts the development of melon seed industry.

On the one hand, due to the continuous improvement of the multi-cropping index of melons as a facility, the crop rotation period is shortened, and the soil continuous cropping obstacles are intensified. As a seed production land, it has a greater impact on the yield of melon seeds; on the other hand, due to the lack of high-yield seed production technology, blindly increase the number of melons. , the plant nutrition cannot be effectively supplied, leading to premature aging of the plant, and it is difficult for melons to mature

Unscientific pollination time and pollination cycle lead to a decrease in hybrid fruit setting rate and false hybrids are prone to appear

Uneven pollination, excessive damage to female flowers, prone to deformed fruit and non-set fruit
