Seed purity refers to the consistency of the representative of the hybrid species. The main reasons for the low purity of corn seeds are: 1 Biological mixed. The isolation zone conditions and de-miscellaneous and inferior qualities have not reached the standards required by the state, and pollination of alien species has caused biological confusion. 2 It is not timely to make a seed. Some of the parental inbred tassels blossomed in the loquat leaves and did not leave in time, resulting in self-inflicted. 3 Seed harvesting, threshing, and storage are not strict, and the panicles are not removed strictly according to quality standards; threshing machines, concentrators, etc. are not thoroughly cleaned, resulting in mixed machinery. Every important link in corn seed production will result in a lower seed germination rate. Parents of the farming system are late for greediness, grouting is not full, and the water content is high. Seeds encountered low temperature, cold damage and frost during the milk ripening period and were forced to harvest. After the ear was harvested, it suffered freezing injury on the drying field, which could reduce the seed germination power. After the seeds are stored in the warehouse, they are stored in dark and damp warehouses with poor sealing. Both of these factors can result in a lower germination rate.
