Quality Identification of Tea breeding
A method for evaluating the quality characters of individuals, types or strains in tea breeding. The quality meaning of tea generally refers to the four factors of "color, aroma, taste and shape", which are collectively referred to as appearance endoplasm. The direct identification of quality is to prepare tea and evaluate its quality according to the picking standards and processing techniques of different kinds of tea. Making tea with a small amount of fresh leaves and small machinery is called "small-scale tea method", that is, the early identification of the quality of young tea trees or individual plants. The indirect identification of quality is based on the correlation between bud leaf shape and finished tea quality, which is identified by field observation and instrumental analysis.

Research Progress of Disease Resistance breeding in Pigs
The goal of high yield usually leads to a decrease in pig resistance. At the same time, pig farm diseases, especially viral infectious diseases, are a serious threat to the health of pigs. Although vaccination played an important role in prevention and treatment, the epidemic of infectious diseases could not be completely controlled and eliminated. In the long run, using genetic methods to improve the resistance of pigs to pathogens, carrying out disease-resistant breeding has the effect of curing the root causes. In the 1930s, some scholars reported that there were differences in sensitivity to Marek's disease among different chicken breeds.
