Marker-assisted selection is the general direction of future breeding
Conventional breeding methods have limitations such as genetic variation and genomic hybridization. In principle, these limitations can be overcome by genetic engineering methods such as recombinant DNA. By using these methods, the genes with definite function can be cloned and the genes can be fast and high.

Identification of tea breeding materials
The characters of breeding materials were observed, the characteristics of various variation materials were analyzed, and the advantages and disadvantages were selected according to the breeding objectives. finally, the methods of breeding new varieties were compared. The content of identification can be divided into three aspects: yield traits, quality traits and resistance. The yield characters of tea plants are mainly reflected in germination density, bud leaf weight, growth rate, growth period, regeneration ability after picking and recovery ability after disaster or trauma, while the quality characters are mainly reflected in the chemical composition, color, hairs,

Breeding of introduced Pig breeds and Application of New breeding techniques
The continuous development and progress of science and technology make it possible for people to explore the laws of nature and reveal biodiversity. The greatest progress of pig breeding in the 20th century is that the daily gain of pigs exceeded 800g / day, the lean meat rate reached more than 60%, the ratio of feed to meat reached 2.8g / ∶ 1, and the body weight of pigs reached more than 90kg in 156days. In recent years, with the continuous development of breeding theory and practice, pig breeding in developed countries has gradually changed from breed selection to specialized breeding.

The latest course of Maize breeding techniques and methods
Seeds are the most important means of production, and new varieties are the core foundation of agricultural scientific and technological progress. Maize breeding and production practice show that 43% to 60% of the increase in maize yield is achieved through excellent varieties and their popularization. therefore, it is important to cultivate and popularize new maize varieties.

How to choose a pig?
Pigs refer to the male and female pigs that are initially reserved for breeding at the end of the breeding phase. Generally speaking, family pigs prefer to keep their own breeding male sows as replacement pigs. So, what kind of backup pig should I choose? Experts warn you: reserve pigs should be physically strong, well-developed, with breed characteristics and high breeding value of breeding pigs. Selection of breeding stock should start from the following points. Healthy and disease-free: Reserve pigs should be healthy and disease-free pigs with normal growth and development, and come from pigs without any diseases.

Selection method of Tibetan Mastiff breeding in Autumn
In order to promote breeding, purification and quality improvement, it is not enough to pay attention to the selection of Tibetan mastiff, we must also pay attention to and strengthen the breeding of Tibetan mastiff. However, it is not the natural mating of the Tibetan mastiff in the place of origin, but is purposefully and meaningfully selected in the performance and sex of the characters.

Conditions and implementation of purebred breeding of Yellow cattle
Yellow cattle is an inherent common cattle breed in China. The number of breeding heads in China ranks first among all livestock or cattle, and the breeding area is almost all over the country. It is mainly used for service in agricultural areas, milk in semi-agricultural and semi-pastoral areas, and milk and meat in pastoral areas. In terms of shape and performance,

Tea cross breeding
The variation of hybrid population was produced by sexual hybridization of tea parents with different genetic characteristics, and then selected to cultivate a new tea variety breeding method. The selection of hybrid parents is related to the success or failure of cross breeding and the level of cross breeding. The general principles are: the parental traits of ① can learn from each other, and the good characters should be outstanding; the adaptability of ② parents to local environmental conditions, especially the materials selected as female parents should have strong adaptability; the flowering period of ③ parents should be consistent, and the knot of female parents should be more consistent.

In order to improve the flavor of tomato, the original flavor of tomato can be found by pan-genome research.
Tomato is a vegetable that exists all the year round, and we often eat this kind of vegetable. Have you noticed that the taste of tomato is very different from that of tomato 20 years ago? today's tomato tastes light and its acidity and sweetness are not very obvious. it's also like today's tomatoes.

Research shows that birth order not only affects a child's personality, but also determines his or her career in the future.
Previous studies have shown that birth order affects a child's personality. But new research confirms that whether you are the eldest, second or youngest child in the family, it can have an impact on your career. Led by psychologist Emma Kenny.

New genes for yield increase of Super Rice have been discovered
In cooperation with the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences, the Super Rice Germplasm Innovation team of the China Rice Research Institute of the Chinese Academy of Agricultural Sciences successfully isolated and cloned one from the local large-grain variety "Baodagi" in Zhejiang Province, which can significantly increase the yield of super rice.

Let the seeds eat less fertilizer and more grain.
Want farmers to use less chemical fertilizer? Maybe the seeds can absorb fertilizer better. Huang Jianhua, director of the Institute of Biotechnology, Shanghai Academy of Agricultural Sciences, is using barley seeds as a breakthrough to study the efficient use of nitrogen fertilizer. If this research is successful, farming can be done.

Problems easily overlooked in the process of selecting and retaining reserve pigs
(1) The selection and retention procedure is unreasonable and the selection and retention process is simplified: in some pig farms, the selection and retention process of reserve pigs is very simple, and there is no fixed procedure. Only after the breeding pig knot test is completed, the selection and retention can be simply evaluated, which is easy to cause imbalance in the selection and retention amount of each bloodline and decline in breeding pig production performance. Therefore, the selection and retention of reserve pigs should have a fixed procedure as a basis. Generally, the selection and retention of reserve pigs should go through three processes: primary selection, middle selection and fixed selection. Primary selection refers to the selection group with 4 times the number of reserved seeds when the farrowing segment is transferred to the breeding segment; middle selection refers to the development from young breeding to fattening.
