Problems solved by technology

In the 1990s, many domestic units used andricide No. 1 (zinc methyl arsenate) and Huasha No. 2 (sodium methyl arsenate) for CHA breeding, and successively bred a number of rapeseed hybrid combinations, but Due to the carcinogenic effect of arsenic compounds, it has not been popularized; gibberellin (CA3), N-C (phosphonic acid methyl) glycine, NaCI, ENE, XP (the main components are unknown) all have certain andricidal effects, but they are not effective for drug application. The technical requirements are harsh, and it cannot be applied in a large area. It is difficult to be a good chemical andricide

Embodiment

[0029] The above-mentioned preparation method steps for the cruciferous chemical androgenic composition:

[0030] 1. Weigh 1 g of 10% bensulfuron-methyl wettable powder.

[0031] 2. Weigh 100 grams of 75% isoproturon wettable powder.

[0032] 3. Mix the above-mentioned bensulfuron-methyl and isoproturon evenly to obtain 101 grams of finished product.

[0033] When in use, dilute 1000 times with PH≈7 water, use 0.1g / L, and use an agricultural sprayer to spray the rapeseed at the bud stage, and spray 3-6ml of the liquid medicine on each plant to obtain the ideal effect.

[0034] The present invention is committed to exploring and optimizing the formula, starting from safety, high efficiency, broad spectrum and low toxicity, screening and compounding binary cruciferous pesticides, successfully tested in rapeseed GMS, CMS and CHA seed production, and tested in CMS Large-scale application in seed production "chemical control micropowder".

[0035] Below is the proof given by the...

example 1

[0036] Example 1 The present invention is to GMS " decontamination and impurity removal " experiment:

[0037] 1. Materials and methods

[0038] 1.1 Materials

[0039] Rapeseed GMS two-line female parent 04-1AB and restorer line 11R are both self-fertile; in this invention, LS-16P knapsack sprayer is used for spraying. Carry out isolated seed production with 60 mesh nylon gauze.

[0040] 1.2 Test method

[0041] The seed production experiment was carried out in Liuying, Mian County Farm; sowing and raising seedlings on September 11, 2005, and transplanting on October 8; the rice in the test site was of medium fertility; the area of ​​the net room was 36.26m 2. Ratio of parents and parents is 1:2; spacing between plants and rows is 70×20cm, double plants of father and mother are transplanted; before transplanting, 3 kg of ammonium bicarbonate and 2 kg of superphosphate are applied to each plot; No. 1 net room and No. 2 net room are set up in the experiment . No. 1 net roo...

example 2

[0059] Example 2 The present invention experiments on CMS "chemical control micropowder":

[0060] 1. Comparison of control effects of different chemical andricides on Shaanxi 2A micropowder

[0061] The experiment set up 3 treatments, 3 repetitions, and a plot area of ​​33m 2 1. The ratio of parents and parents is 2: 2, and the cultivation management with high fertilizer and high yield induces the production of a large amount of micropowder; combine Qinyou No. 2, female parent Shan 2A; medicament selection: ① the present invention sprays 1 times; ② Huasha No. 2 sprayed once at a concentration of 6ml / L. This experiment builds on the previous year's experiment.

[0062] 1.1 Material method

[0063] Huasha No. 2 was provided by the Guangzhou Institute of Chemical Technology, Chinese Academy of Sciences; the spraying period is based on the "flat head" period of the main inflorescence of the female parent, and the period for investigating the micropowder: it is carried out in t...

Abstract

The invention discloses a chemical male sterilant composition of cruciferae crops and an application method thereof. The chemical male sterilant composition is prepared by uniformly mixing bensulfuron methyl and isoproturon in a certain ratio. When the chemical male sterilant composition is sprayed in the 'flat head' period of rape, the male killing of the cruciferae rape is thorough, the male abortion rate is 100 percent, the pistil fertility is normal, no adverse effect is caused to growth and development of plants, the outcrossing rate is normal, and the seed hybrid rate is 100 percent. The male sterilant performs 'chemical impurity removal' in rape recessive nucleus male sterile seed production, 'chemical control of micro powder' in cytoplasm male sterile seed production and 'chemical breeding' of common rape varieties. The chemical male sterilant composition of the invention has the advantages of simple method, low production cost, environmental friendliness, easy application and easy popularization.

Description

Technical field: [0001] The invention belongs to the crop breeding category, and relates to a chemical andricide composition for cruciferous crops, and an application method in rapeseed GMS, CMS, CHA seed production (breeding). technical background: [0002] Brassicaceae (rape, cabbage, cabbage, white radish) crops occupy an important position in agricultural products, and the planting area of ​​rapeseed accounts for about 90% in Brassicaceae; the hybrid advantage of Brassicaceae crops such as rape is very obvious. At present, domestic There are three main ways to utilize hybrid vigor in rapeseed: 1. Cytoplasmic male sterility (CMS), 2. Recessive nuclear male sterility (GMS), 3. Chemical andricidal (CHA)-induced male sterility. [0003] CMS is a cytoplasmic male sterile line. As early as the 1970s and 1980s, with the breeding of Polima CMS and Shan 2A CMS, the hybridization of rapeseed in my country has realized three-line matching, and the hybridization advantage of rapesee...
