Abstract:The haploid induction rate and artificial chemical doubling rate of sweet corn were studied by using 6 basic materials of sweet corn(Japanese sweet corn material, Korean sweet corn material and American sweet corn material) selected by the breeding team of Jilin Agricultural Science and Technology University as female parent, Jikeyou 115 and Jikeyou 209 as male parent. The results showed that both basic female parent materials and male induction lines could affect haploid induction rate of sweet corn. The haploid induction rate from high to low was Japanese sweet corn material, Korean sweet corn material and American sweet corn material. After chemical doubling,the haploid loose powder plant rate and seed-setting plant rate from high to low were Japanese sweet corn material,American sweet corn material and Korean sweet corn material. In addition, the induction rate of Jikeyou 115 was5.9%. It was significantly higher than that of Jikeyou 209. The utilization of Jikeyou 115 should be strengthened in haploid breeding of sweet corn.
