Breeding method of low-temperature-resisting and weak-light-resisting female lines of Haiyang white cucumbers and application of breeding method

Abstract

The invention relates to a crop breeding technology and in particular relates to a breeding method of low-temperature-resisting and weak-light-resisting female lines of Haiyang white cucumbers, and belongs to the field of hybridization breeding. The breeding method comprises the following steps: firstly, selecting white cucumber varieties of Haiyang, and carrying out population improvement to separate selfing lines as female parents; then taking Northeast dry cucumber female line materials as male materials; after hybridization, carrying out a plurality of times of back-crossing; and selecting full-female germplasm of the low-temperature-resisting and weak-light-resisting Haiyang white cucumbers. Along the success of the breeding, the breeding method can be directly used for production, and a breeding progress of the Haiyang white cucumbers is accelerated, so that the breeding method has important practical significance on increasing additional values of the Haiyang white cucumbers and related products, accelerating industrialized development paces of the Haiyang white cucumbers, and further improving the brand awareness of the Haiyang white cucumbers.

Description

technical field [0001] The invention relates to a crop breeding technology, in particular to a method for selecting a female line of "Haiyang White Cucumber" specially for greenhouses, and belongs to the field of hybrid breeding. Background technique [0002] "Haiyang White Cucumber" is a popular fruit, because of its low plant seed setting rate, intolerance to low temperature and other factors, hindering the large-scale planting and periodic supply of white cucumber. Haiyang also tried hybrid breeding locally, but due to the limitations of breeding materials and breeding methods, none of them succeeded. [0003] With the increasing demand for white cucumbers, the research on Haiyang white cucumber hybrids urgently needs to be solved, especially to breed new varieties that are resistant to low temperature and low light, suitable for overwintering greenhouse planting, so as to meet the periodic supply of Haiyang white cucumbers, This requires innovation on the original germp...
