Abstract:: The onion variety ‘Zuanshihong’ was used as material,the percentage of seed plants with different bolting numbers in the group,the seed yield per plant,single flower bulb yield,net seed weight rate,thousand seed weight and seed germination rate of seed plants with different bolting numbers were studied by using the method of randomized block experiment design and conventional cultivation in order to provide technical support for onion breeding and seed selection.The results showed that the group with 5 bolting numbers were the largest,reaching 23.75%.The total number of seed plants with 4-7 bolting numbers were more,reaching 76.88%.The plant with 2 bolting numbers were the least,only 1.25%.The more bolting the higher yield per plant.The highest seed weight per plant was 10-11 bolting plants,the average was 69.7 g,and the lowest was 2 bolts,only 11.5 g.The seed weight of a single flower bulb decreased with the increase of bolting number.The net weight rate of seeds showed a slightly lower trend between the two sides；the 1 000-seed weight of different bolting numbers had significant difference,the maximum was 3.966 g,the minimum was 3.235 g,but the regularity was not obvious；the germination rate of seeds with different bolting numbers had no significant difference,the highest was 98.0%,the lowest was 92.6%,and there was no obvious regularity.
