摘  要：
以6份吉林农业科技学院育种课题组选育的甜玉米基础材料为母本(日系甜玉米材料、韩系甜玉米材料、美系甜玉米材料),以吉科诱115和吉科诱209为父本进行杂交诱导,研究甜玉米单倍体诱导率和人工化学加倍率。结果表明,母本基础材料和父本诱导系均会影响甜玉米单倍体诱导率。单倍体诱导率从高到低依次是日系甜玉米材料、韩系甜玉米材料、美系甜玉米材料;化学加倍后单倍体的散粉株率和结实株率从高到低依次是日系甜玉米材料、美系甜玉米材料、韩系甜玉米材料;此外,吉科诱115的诱导率为5.9%,显著高于吉科诱209,在甜玉米单倍体育种中应加强对吉科诱115的利用。

摘  要：
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.
