Wusu City has sufficient sunshine, high summer temperatures, large temperature difference between day and night, low rainfall and good irrigation conditions, which is conducive to growth and development of cotton. In order to prevent miscellaneous degradation, maintain good variety, and accelerate the promotion and application of new varieties, we should do the following aspects.

I. Establishing a breeding base for improved varieties: Choose a village team that has convenient transportation, good soil fertility, convenient irrigation conditions, peasant households with scientific and technological awareness, and village leaders’ attention, strong technical force, and concentrated farmers, as a thoroughbred Breeding base.

Second, do a good job in preventing miscellaneous items: This year, the city has more than 10,000 acres of fine-bred cotton breeding areas, and the seed fields in the Liangcai area will go through the flowering and maturation stages respectively. In August, they will be seed management departments and plant quarantine. The technical personnel of the department form a joint inspection team to carry out inspections and quarantines on a village-by-village, household-by-household, block-by-block basis. Those who meet the seed quality standards are issued with a field inspection certificate, and unqualified seed fields are resolutely eliminated and will not be acquired.

Third, the establishment of seed sales files: Every bag of seeds sold to cotton farmers, were sampled by the farmers personally loaded into the sample bag, and sealed in person in the company's archives for registration.
