Embodiment 1

[0070] Example 1 Genetic Analysis Test of Maple Leaf Cucumber Plant Mutant CC81221

[0071] (1) Test materials

[0072] The inventor discovered a maple leaf in the inbred line material of the offspring of multiple compound crosses of farm varieties Tangshan Qiugua, Baiye San and European fresh cucumber varieties planted in the Shangzhuang Experimental Greenhouse, Haidian District, Beijing in the spring of 2012 type mutant, and named it CC81221, its photo is shown in figure 2 , image 3 .

[0073] The plant of the genus Cucumis (Cucumis sativus L.) CC81221 has been preserved on October 12, 2015 in the General Microbiology Center of the China Committee for the Collection of Microbial Cultures (the preservation address is: Courtyard 3, No. 1 Beichen West Road, Chaoyang District, Beijing No. Institute of Microbiology, Chinese Academy of Sciences), the deposit number is: CGMCC No.11285.

Embodiment 2

[0099] Embodiment 2 is cultivated to have maple leaf type cucumber plant variety by hybridization method

[0100] Cucumber plants with maple-leaf leaves were bred by using cucumber plants with maple-leaf leaves CC81221 or cucumber inbred lines, F1 hybrids or hybrids derived therefrom as maple-leaf-leaf donors. Therefore, any cucumber plant with maple-leaf leaves selected by the method of the present invention and the cucumber plant with maple-leaf type CC81221 or derived from it all belong to the scope of the present invention.

[0101] (1) On May 25, 2012, the test was carried out in the experimental shed in Haidian, Beijing. The experimental shed was closed and isolated with insect-proof nets. The cucumber material CC81221 with maple leaf-shaped leaves was used as one of the parents, and the cucumber ecological breeding with Beijing Beinong Sanyi was carried out respectively. Three different types of common leaf inbred lines provided by the Science and Technology Center: den...

Embodiment 3

[0109] Example 3 Utilize the backcross method to select and breed maple leaf type leaf cucumber variety test

[0110] The main purpose of the backcrossing method used in the present invention is to alter or replace the leaf shape of the original variety while retaining substantially all other desirable genetics, as well as the desirable physiological and morphological composition of the original variety.

[0111] The maple-leaf type leaf is a characteristic controlled by a single recessive nuclear gene. In this case, the test of the offspring must be introduced in the backcrossing step, that is, the phenotypic test is carried out on the corresponding selfed offspring of each backcrossing generation, In order to determine which backcross plants carry the recessive gene encoding maple-type leaves.

[0112] The backcrossing process can be simplified and accelerated by using molecular markers such as SSR, RFLP, SNP or AFLP markers.

[0113] (1) On May 25, 2012, it was carried out...

Abstract

Provided is a mutant cucumber plant CC81221 having a maple-leaf-type split leaf or a cucumber plant having a maple-leaf-type leaf single recessive nuclear gene; also provided is a method for breeding, molecular identification, and application of the maple-leaf-type cucumber plant.

Description

technical field [0001] The invention relates to the field of plant leaf shapes and breeding methods thereof, in particular to maple-leaf cucumber plants, as well as their breeding methods and identification methods. Background technique [0002] Cucumber (Cucumis sativus L.) is a vine with large leaves. The photosynthetic area refers to the size, distribution and photosynthetic efficiency of the leaf area. For cucumber cultivation, especially for off-season facility cultivation in high latitude areas, it has great influence on yield, fruit quality and resistance. Disease, etc. have a direct impact. Leaf is the material basis of plant photosynthesis, and leaf is also an important platform for the exchange of air, water and energy in the ecosystem. Leaf area index (LAI), also known as leaf area index, is a dynamic index reflecting the size of crop populations. Within a certain range, crop yield increases with the increase of leaf area index. When the leaf area index increase...
