Problems solved by technology

However, long-term continuous breeding in different places in the north can easily lead to the degradation of the species, especially the serious degradation of the disease resistance and stress resistance of the variety. In production, poor growth and fruit setting rate often occur due to the weakening of the variety's disease resistance and stress resistance. Low and severely reduced production

Embodiment 1

[0038] Embodiment one: 'Huangjing' watermelon seed propagation method

[0039] (1) The method of promoting early breeding in local greenhouses of the male and female original species of 'Huangjing':

[0040] In the regions of Jiangsu, Zhejiang, Shanghai and Anhui, from February 5th to February 20th every year, the male and female breeder seeds of 'Huang Jing' (selected by the breeders of Shanghai Academy of Agricultural Sciences) were raised in hotbeds. The seedling substrate is: peat soil: paddy soil: refined organic fertilizer = 3:2:1 mixed substrate. When the seedlings are about 25 days old, transplant the seedlings into large and medium sheds (6-meter standard span type, 8-meter standard span type, linkage steel frame greenhouses) or glass greenhouses equipped with insect-proof isolation nets. Spread 225kg / hm on the field before planting 2 Lion horse brand compound fertilizer (N:P:K=15%:15%:15%)+225kg / hm 2 Potassium sulfate is used as base fertilizer after one-time plow...

[0048] Embodiment two: 'Shengnvhong No. 3' watermelon seed propagation method

[0049] (1) The method of promoting early breeding in local greenhouses of the male and female original species of 'Shengnvhong 3':

[0050]In Jiangsu, Zhejiang, Shanghai and Anhui regions, from February 5th to February 20th every year, the male and female breeder seeds of Shengnvhong 3 (selected by the breeders of Shanghai Academy of Agricultural Sciences) were raised in hotbeds. . The seedling substrate is: peat soil: paddy soil: refined organic fertilizer = 3:2:1 mixed substrate. When the seedlings are about 25 days old, transplant the seedlings into large and medium sheds (6-meter standard span type, 8-meter standard span type, linkage steel frame greenhouses) or glass greenhouses equipped with insect-proof isolation nets. Spread 225kg / hm on the field before planting 2 Lion horse brand compound fertilizer (N:P:K=15%:15%:15%)+225kg / hm 2 Potassium sulfate is used as base fertilizer after one-t...

Embodiment 3

[0058] Embodiment three: 'Shen Kang 988' watermelon seed propagation method

[0059] (1) The method of promoting early breeding in local greenhouses of the male and female original species of 'Shenkang 988':

[0060] In the areas of Jiangsu, Zhejiang, Shanghai and Anhui, from February 5th to February 20th every year, the male and female breeder seeds of 'Shenkang 988' (selected by the breeders of Shanghai Academy of Agricultural Sciences) were raised in hotbeds . The seedling substrate is: peat soil: paddy soil: refined organic fertilizer = 3:2:1 mixed substrate. When the seedlings are about 25 days old, transplant the seedlings into large and medium sheds (6-meter standard span type, 8-meter standard span type, linkage steel frame greenhouses) or glass greenhouses equipped with insect-proof isolation nets.

Abstract

The invention provides a seed breeding method keeping watermelon variety nature. The method comprises the following steps of: (1) promote early breeding of a parent breeder seed of a new watermelon variety in a greenhouse in regions of Jiangsu, Zhejiang, Shanghai and Anhui, (2) performing generation-skipping breeding of the parent breeder seed of the new watermelon variety in the northwest region,and (3) performing large-scale breeding of a hybrid seed of the new watermelon variety in the northwest region. The seed breeding method keeping the watermelon variety nature stabilizes and improvesdisease resistance and stress resistance of a parent and the hybrid seed of a southern cultivation watermelon, significantly improves quality and a yield of the parent and the hybrid seed of the southern cultivation watermelon variety at the same time, and guarantees the supply quality and quantity of improved seeds for large-scale demonstration and popularization of the watermelon variety.

Description

technical field [0001] The invention belongs to the technical field of breeding of improved varieties of crops, and in particular relates to a method for breeding seeds of watermelon varieties. Background technique [0002] Watermelon (Citrullus lanatus) originated in the tropical African desert, and belongs to a typical climate-loving, light-loving and dry-loving crop. Northwest China has unique natural climate resources for watermelon cultivation and production. However, in the long-term natural domestication and artificial selection process, watermelon varieties have differentiated into multiple ecotypes. At present, the watermelon varieties cultivated in my country are mainly divided into Northwest ecotype, North China ecotype, and South China ecotype according to different ecological geographical locations. and East Asian ecotypes. The watermelon varieties cultivated in Jiangsu, Zhejiang, Shanghai and Anhui regions mainly belong to the South China ecotype and East Asia ...
