Embodiment 1

[0034] Example 1: Breeding of Chinese pumpkin material 1292 and Quanyou 1 without vine oblate seeds

[0035] 1. In the winter of 2005, the homozygous material 1092 of the oblate Chinese squash without vines and the homozygous material 1066 of the oblate Chinese squash with long vines were crossed at the Sanya base in Hainan in the winter of 2005; 2.5cm long and 1.3cm wide;

[0036] 2. F 1 It was planted in Hefei, Anhui in the spring of 2006. It showed no vines, oblate fruit, seed size between 1092 and 1066, and 350 seeds per fruit. Using 1066 as the recurrent parent to backcross once to obtain BC 1 ;

[0037] 3. BC 1 In the winter of 2006, the performance segregation was planted in Sanya Base, Hainan, and then the recurrent parent 1066 was backcrossed with all BC1 plants to obtain BC 2 , select a single fruit without vines, with a seed board length of 2.2-3cm and a board width of 1.1-1.5cm;

[0038] 4. BC 2 Planted in Hefei, Anhui in the spring of 2007 and still showed s...

Embodiment 2

[0042] Example 2: Breeding of Chinese pumpkin material 1295 and Quanyou 2 without vines

[0043] 1. In the spring of 2010, the homozygous material 1092 of Chinese squash without vines was crossed with the homozygous material 1095 of Chinese squash with long vines and long tubes at the base in Hefei, Anhui in the spring of 2010; The number of seeds of a single fruit is 520;

[0044] 2. F 1 Planted in Sanya Base, Hainan in the winter of 2010, the plants showed no vines, and the fruit was flat pear-shaped. Using 1095 as the recurrent parent to backcross once to obtain BC 1 ;

[0045] 3. BC 1 In the spring of 2011, it was planted and separated at the base in Hefei, Anhui Province, and it was beneficial to BC 1 All are self-crossed, and then the reincarnated parent 1095 is used with all BC 1 Planted single plant backcross to obtain BC 2 , select BC with 450 seeds per fruit 2 Single plant is self-crossed to obtain BC 2 f 2 ;

[0046] 4. Select BC with no vines, long tube s...

Abstract

The invention provides a breeding method and application of a high-quality Chinese pumpkin variety without vines and seeds, and relates to the technical field of crop breeding. The breeding method comprises the following steps: with a vine-free oblate spheroidal Chinese pumpkin homozygous material A and a long-vine Chinese pumpkin homozygous material B with seed plate length of 2.5cm or more, plate width of 1.3cm or more, or single fruit seed number of 520 or more, and with a parent B as a recurrent parent, carrying out continuous optimal backcrossing and self-crossing to obtain BCn+1Fm+1; selecting a vine-free BCn+1Fm+1 single plant with seed plate length of 2.2-3 cm, plate width of 1.1-1.5 cm or single fruit seed number of 450 or more, and carrying out continuous self-crossing to obtaina homozygous inbred material C; and crossbreeding the homozygous inbred material C and a long-vine Chinese pumpkin homozygous material E to obtain the Chinese pumpkin without vines and seed. The breeding method provides a special variety of Chinese pumpkins for seeds, which combines the excellent traits of three parents, has no vines, has more than 350 seeds on each single fruit, excellent plate length, plate width and 100-grain weight, is conducive to close planting and can bring considerable economic benefits to enterprises and farmers.

Description

technical field [0001] The invention relates to the technical field of crop breeding, in particular to a breeding method and application of a high-quality Chinese pumpkin variety without vine seeds. Background technique [0002] Pumpkin for seeds uses seeds as the main edible organ, and is a traditional agricultural by-product and foreign trade commodity in my country. Pumpkin seeds are rich in essential fatty acids, amino acids, phytosterols, minerals, vitamins, and polysaccharides.
