Embodiment 1

[0056] Example 1: Such as figure 1 As shown, the selection and breeding of vineless long-necked cylindrical Chinese pumpkin material 1130 and Quanguan No. 1

[0057] 1. In the winter of 2005, the vine-free flat spherical Chinese pumpkin homozygous material 1092 was crossed with the long-vine long-necked cylindrical Chinese pumpkin homozygous material 1076 at the Sanya base in Hainan;

[0058] 2. F 1 Planted in Hefei, Anhui in the spring of 2006, the plants showed no vines and the fruits were flat pear-shaped. The BC was obtained by backcrossing with 1076 as the recurrent parent. 1 ;

[0059] 3. BC 1 In the winter of 2006, it was planted in Sanya, Hainan, showing separation, and then backcrossing the reincarnation parent 1076 with a vineless, long-necked cylindrical single plant to obtain BC 2 ;

[0060] 4. BC 2 In the spring of 2007, it was planted in Hefei, Anhui Province, and still showed separation, and then backcrossed the vineless, long-necked cylindrical single plant with the rei...

Embodiment 2

[0064] Example 2: Such as figure 2 As shown, the selection and breeding of vineless long cylindrical Chinese pumpkin material 1235 and Quanguan No. 2

[0065] 1. In the spring of 2010, hybridization of the homozygous material 1128 of non-vine flat spherical Chinese pumpkin with the homozygous material 1171 of long-vine long cylindrical Chinese pumpkin in Hefei base in Anhui;

[0066] 2. F 1 Planted in the Sanya base in Hainan in the winter of 2010, the plants showed no vines and the fruits were flat pear-shaped. Using 1171 as the reincarnation parent, backcrossed once to obtain BC 1 ;

[0067] 3. BC 1 was planted and separated in Hefei, Anhui, in the spring of 2011. 1 The vineless, long tube-shaped single plant in the self-crossing to obtain BC 1 F 2 ;

[0068] 4. In the winter of 2011, the spring of 2012, the winter of 2012, the spring of 2013, the winter of 2013, the spring of 2014, and the winter of 2014, it was continuously selfed for 7 generations, and the plants were continuousl...

Embodiment 3

[0070] Example 3: Selection and breeding of no vine, long curved cylindrical Chinese pumpkin material 1298 and Quanguan No. 3

[0071] 1. In the winter of 2010, the vineless long-necked cylindrical Chinese pumpkin homozygous material 1130 was crossed with the vine-long curved cylindrical Chinese pumpkin homozygous material 1133 at the Sanya base in Hainan;

[0072] F 1 Planted in Hefei, Anhui in the spring of 2011, the plants showed no vines and the fruits were long-necked cylinders. 1133 was used as the reincarnation parent to backcross once to obtain BC 1 ;

[0073] BC 1 In the winter of 2011, it was planted in Sanya, Hainan, showing separation, and then backcrossing the reincarnation parent 1133 with a vineless, long-curved cylindrical single plant to obtain BC 2 ;

[0074] In the spring of 2012, the winter of 2012, and the spring of 2013, the same requirements were adopted to select three consecutive backcrossings. BC 5 In the winter of 2013, it was planted in Sanya, Hainan. 5 The ...

Abstract

The invention provides a breeding method of a vineless Cucurbita moschata Duch and an application thereof, and belongs to the technical field of crop breeding and plant protection. The method comprises the following steps: 1, hybridizing a vineless pumpkin homozygous material A and a long type Chinese pumpkin homozygous material B as parents, so as to obtain F1; 2, using a parent B as the recurrent parent to continuously backcross with the F1 for n times, and continuously optimizing to obtain BCn, continuously backcrossing the BCn for m generations, continuously optimizing to obtain homozygous backcross line material BCnFm+1; 3, hybridizing the BCnFm+1 with the long type Chinese pumpkin homozygous material C to obtain the vineless Cucurbita moschata Duch. The technical problem that Cucurbita moschata Duch is not beneficial to close planting in the prior art is solved. The vineless Cucurbita moschata Duch is early-maturing, in long rod shape, good in taste, beneficial to close planting and high in the yield. According to the difference of the ecological conditions in the north and south regions, the remote continuous optimization is carried out, the regional adaptability is high, and considerable economic benefits can be brought to enterprises and farmers.

Description

Technical field [0001] The invention relates to the technical fields of crop breeding and plant protection, in particular to a breeding method and application of this type of pumpkin without vine honey. Background technique [0002] Pumpkin is an annual crop of the Cucurbitaceae squash. At present, there are many varieties commonly cultivated at home and abroad, and there are mainly three cultivated varieties: Chinese pumpkin (commonly known as Japanese squash), American squash (commonly known as zucchini), and Indian pumpkin (commonly known as winter squash). Among the existing varieties of Chinese pumpkins, the most planted are honey-type pumpkins. The fruit of the honey type pumpkin has an enlarged bottom, a slightly longer body, similar to a papaya shape, and the old ripe fruit is yellow with light yellow mottling. Its flesh is fine, sweet and waxy, with excellent quality and strong resistance to virus diseases. [0003] Although the honey type pumpkin has many of the above-...
