Application of anther Culture technique in Rice breeding
Anther culture using the first generation of disease-resistant plants of backcross can transfer disease-resistant genes into japonica rice in a short time, which speeds up the process of disease-resistant breeding of japonica rice. Zhejiang Agricultural University has been matching since 1975. Anther culture was carried out in 1976 and Dan 209, a variety resistant to rice blast and bacterial blight, was bred in 1977. After only 3 years, the resistance genes of two diseases were transferred at the same time, and the breeding speed and efficiency greatly exceeded the conventional research methods of Japanese scholars. This study also discussed the application of anther culture in improved variety breeding.

The pollination method of peach trees is fast and good.
Artificial pollination and artificial pollination can be used. Although peach trees can bear fruit by self-pollination, peach trees with cross-pollination have high fruit setting rate, good quality and high yield. When cultivated in greenhouse, cross-pollination is possible because of poor air mobility, low temperature and high humidity in greenhouse.

Management measures of planting peach trees
Strengthening the growth of nutritious branches and the expansion of leaf area provide the basis for making nutrients for flower bud differentiation, which is beneficial to flower bud differentiation. If there are too many fruits in that year, the tree will be weakened, resulting in the weakening of branch growth in that year. On the contrary, if the plant grows too much, it consumes
