Problems solved by technology

[0005] Experiments have confirmed that mustard mustard has very obvious heterosis, which is mainly reflected in its strong growth potential and high yield of tumor-shaped stems. At present, domestic research on the use of heterosis in spring mustard mustard is still in its infancy.

Embodiment Construction

[0036] Such as image 3 As shown, the method for breeding new varieties of pickled mustard suitable for mechanized harvesting of the present invention comprises: taking Yuyao shrinking head seed cytoplasmic male sterile line 13-06A as the female parent, and flat leaf type Pingyang mustard mustard inbred line 13-09 as the male parent Hybrid seed production, bred a new variety of pickled mustard - "Yongza No. 6".

[0037] Among them, such as figure 1 As shown, the female parent was obtained through 5 generations of backcrossing in 2007 with winter mustard CMS line 07W-06 as the sterile source and spring mustard inbred line YS07-06 (shrinking head species) as the recurrent parent. The source of sterility is OuxinA cytoplasmic male sterility source, and the species of dwarfed head is Yuyao dwarfed head species. Specifically, the first generation of F1 (07W-06-08) was obtained by crossing the sterile source 07W-06 with the Yuyao shrinking head species YS07-06, and the second gene...

Abstract

The invention relates to the technical field of vegetable breeding, and particularly discloses a method for breeding a new variety of preserved szechuan pickle suitable for mechanical harvesting, which comprises the following steps of: performing hybrid seed production by taking a preserved szechuan pickle cytoplasm male sterile line 13-06A as a female parent and a plate-leaf type inbred line 13-09 as a male parent to breed a new variety of preserved szechuan pickle Yongzhou No.6; the novel preserved szechuan pickle variety bred by the invention is suitable for mechanical harvesting and has excellent processing characters; the height of the base part of the tumor stem to the ground is 2.9 cm, and the lodging rate of the rhizome is 2.3%; after harvesting by a harvester, the loss rate of the tuberous stems is 6%; the hybrid variety is the first hybrid variety suitable for mechanical harvesting in China, the distance between the base part of the tumor-shaped stem and the ground is more than 2 cm higher than that of the existing variety in Zhejiang province, and the harvesting effect is good; compared with the existing conventional variety, the mature period is earlier, and the harvest period is shortened.

Description

technical field [0001] The invention relates to the technical field of vegetable breeding, in particular to a method for selecting a new mustard variety suitable for mechanized harvesting. Background technique [0002] Mustard mustard (raw material stem mustard) is one of my country's famous special products, and it is also known as the world's three famous pickles along with European sauerkraut and Japanese pickles. Zhejiang Province is a traditional production area of ​​mustard mustard, with a stable cultivation area of ​​about 350,000 mu. Among them, Ningbo is mainly distributed in the coastal plain towns of Yuyao City and Cixi City. Yuyao City introduced mustard mustard for trial planting in 1962. After more than 50 years of experimental research, demonstration and promotion, the mustard mustard industry has developed rapidly. The mustard mustard production base is 100,000 mu, with an annual output of 300,000 tons of fresh heads. 22 leading enterprises for mustard musta...
