Problems solved by technology

According to the data, so far, the mustard varieties mainly planted in production are basically conventional varieties. In recent years, Chongqing has used the male sterile line to select and breed a new generation of hybrid varieties, Fuza No. 1 and No. 2; Sichuan plate leaf type has not yet been used. A report on the breeding of new varieties of pickled mustard and zhejiang semi-broken leaf mustard through sexual crossbreeding

Embodiment Construction

[0017] The present invention is further described below in conjunction with specific examples.

[0018] Taking the application of new variety selection in the main producing area of ​​mustard mustard in Zhejiang from 2000 to 2004 as an example, the steps are as follows:

[0019] In late March 2000, a stable inbred line of mustard mustard (code NZ00) from Sichuan was used as the female parent, and a stable inbred line (semi-broken leaf type) of Yuyao local variety (code YS00) was used as the male parent , to obtain the inter-variety hybrid F 1 (NZ / YS), Harvested F 1 The seeds were planted in the experimental base of our hospital in October 2000. From the seedling stage, according to the traits of the female parent plant, F 1 The leaf shape of each seedling is removed, and false hybrids (plate leaf type) are eliminated, and diseased plants and deformed plants are eliminated at the same time.

[0020] In the last ten days of March 2001, the mustard hybrids were planted in Tian...

Abstract

The invention pertains to the cruciferous vegetable breeding technique field. The stable inbred line of the plate leaf type tuber mustard(code: NZ00) stemming from Szechwan is used as female parent; the stable inbred line(semi-leaf piece type) of Yuyao local species(code: YS00) is used as male parent; the female parent and the male parent are hybridized to acquire the hybrid between species F1, and the filial generation is bred through genealogical breeding. The breeding tuber mustard in the invention agrees with the breeding target, has relatively early picking time, light green knotty bark, more knotty projections, non-concave top, and is not easy to accumulating water in rainy days; the knotty bark is thin and has low water content, faster dehydration speed and crisp flesh; the invention is especially suitable for rice winter fallow field planting.

Description

technical field [0001] The invention belongs to the technical field of cruciferous vegetable breeding, and in particular relates to a method for breeding sexual hybrids of mustard mustard ( mustard mustard ), in particular to a new sexual hybrid variety "Yongzai No. 1" of mustard mustard ( mustard). breeding. Background technique [0002] The main production areas of pickled mustard are Zhejiang, Sichuan and Chongqing. Among them, since the 1990s, the cultivated area in Zhejiang Province has basically stabilized at about 400,000 mu, making it the province with the largest cultivated area in the country. Among them, Yuyao's cultivated area has been stable at about 150,000 mu in recent years, with an annual production of 500 million kilograms of fresh mustard. It is currently one of the largest production bases of mustard in China. There are more than 100 processing enterprises with an annual output value of 1 billion yuan. The production and processing of pickled mustard has...
