A Single Recessive Photoperiod and Temperature Sensitive Genic Male Sterile Line Yahuang 396a in Cotton
1. The present situation and problems of breeding and seed production by using heterosis 1.1. The technique of artificial or chemical emasculation hybridization is simple, any two varieties can be parents of each other, anthesis emasculation and artificial pollination can be used, and chemical emasculation hybridization can also be used for seed production. The advantages are easy to make full use of existing variety resources, strong randomness of hybrid selection, free combination, and partial combination can use F2. Disadvantages are labor intensity, labor, high cost, F2 heterosis than F1 more decline. 1.2 cells

Cotton "Dong a" Genic male sterile Germplasm
The cotton male sterile plant was found in the field in 1972, and the cotton "Dong A" genic male sterile germplasm was successfully cultivated after 3 years and 6 seasons. Its sterile traits are mainly controlled by a pair of recessive nuclear genes. It has the advantages of stable inheritance of sterility, easy transfer, strong combining ability, wide restorer line, about 50% sterile plant rate and 100% sterility per plant. It has the characteristics of high yield and wide adaptability. A derived male sterile line 1 was bred by using Dong A genic male sterile germplasm. Among them, several derived male sterile lines were combined and 12 hybrids which had been approved were selected.

Dairy sterilization: how about the level of low-temperature sterilized fresh milk? Is the quality of low temperature raw dairy products good?
Fresh milk sterilization can be divided into two simple methods, one is low temperature sterilization, the other is high temperature sterilization, each has its own supporters. Consumers who support low-temperature sterilization believe that fresh milk can retain more nutrition without high-temperature sterilization, while consumers who support high-temperature sterilization think that fresh milk is easy to go bad and high-temperature sterilization can ensure hygiene.

Technical specification for production and sterilization of bag edible fungi
Whether the production of bag edible fungi is sterilized thoroughly or not is related to the success or failure of production. Sterilization is to keep the production medium through a certain temperature and pressure for a certain time, kill the spores of miscellaneous bacteria (bacteria) in the medium, promote the growth of microorganisms (such as Flammulina velutipes and Lentinus edodes mycelium), and improve the yield and quality. Improve the benefit of the grower. No matter what form of sterilization stove is adopted, the principle of sterilization is roughly divided into two kinds, one is high-pressure sterilization, the other is atmospheric pressure sterilization. Atmospheric pressure sterilization has the advantages of low investment, simple facilities, convenient operation, safety,

Seed production techniques of Cotton male sterile Lines
The technology of cotton male sterile line seed production uses insect-assisted pollination male sterile line hybrid seed production method, which overcomes the shortcomings of artificial de-pollination hybrid seed production method, which is widely used at present, such as time-consuming and labor-consuming, high intensity of work, complex management of seed production field and high cost of seed production. The labor consumption can be reduced by more than 50%, and the purity of hybrid seeds can be further improved. It is the most ideal way to produce cotton hybrid seeds. The seed production technique of cotton male sterile line is to cultivate recessive low phenol markers.

Sterilization, inoculation and Culture of Lentinus edodes medium
The sterilization of a strain culture medium is the key to the success or failure of strain production. There are a large number of microorganisms in the unsterilized medium, which often lead to bacteria pollution and loss to production. At present, atmospheric steam sterilization is commonly used by mushroom farmers. The atmospheric pressure sterilization stove of atmospheric pressure steam sterilization is made of brick. choose an iron pot with a diameter of 110 centimeters, a drum with a height of 100 centimeters and a diameter of 120 centimeters with brick, and smooth it with cement inside and outside. After loading the culture medium into the sterilizing pot, use thicker plastic.

Breeding of Purple Marker male sterile Lines of Rice in Guangxi
Xianhong An and Zhihong A, two rice male sterile lines with purple leaf markers, were developed by a research group led by Liang Shirong, an excellent expert in Guangxi, and Deng Guofu, vice president of Guangxi Academy of Agricultural Sciences. On August 3, 2007, it passed the field technical appraisal organized by the Office of Guangxi crop Variety approval Committee. After strict field investigation and indoor microscopic examination, and listening to the technical report and answering questions of the research group, the expert group agreed that Xianhong An and Zhihong A had stable agronomic characters, stable sterility and flowering.

The key to successful cultivation of Lentinus edodes lies in sterilization
"if the sterilization is not complete, the cultivation of mushrooms will kill people", which is the image expression of the cultivation failure caused by incomplete sterilization in the cultivation of Lentinus edodes. Sterilization is a very important link in the process of cultivating Lentinus edodes, which is related to the success or failure of cultivation. First of all, carefully check the sterilization stove before mixing Lentinus edodes. It is necessary to check the sealing degree of the sterilization stove, the degree of flame combustion and whether the cold air is unobstructed, so as to ensure that there are no accidents in the sterilization process. Secondly, after bagging is finished, immediately put it into the bag and fill it according to 3.

Auricularia auricula planting: how to sterilize Auricularia auricula under atmospheric pressure?
How does Auricularia auricula sterilize under atmospheric pressure? Please introduce the method of normal pressure sterilization of Auricularia auricula can refer to the following: 1, when loading the pot, there should be a certain gap between the basket and the basket to prevent the poor flow of steam and affect the effect of sterilization. 2. After a large amount of steam is produced, be sure to open the exhaust hole to vent the air, when the temperature at the bottom of the pot.

Sterilization and inoculation of Lentinus edodes
Lentinus edodes culture medium mostly uses the method of atmospheric pressure and high temperature sterilization to achieve the purpose of killing pests. (1) bag material sterilization: put the bag in the human sterilization stove and sterilize under normal pressure. Before putting the material bag into the stove, add enough water to the steamer first. When the material bag is loaded into the stove, it should not be installed in the shape of "product". It should be discharged overlapping from top to bottom, leaving a gap between the row and the discharge to make the air flow up and down smoothly. After the bag entered the warehouse, the fire immediately burned, so that the temperature quickly rose to 100 ℃ within 6 hours and lasted for 24 hours. To achieve the goal of "head attack, tail protection,
