摘　　要：为了获得金玉甜1号高产制种的父母本最佳播期差以及母本最佳载培密度,研究了甜玉米金玉甜1号制种父母本的花期相遇以及栽培密度对其制种产量的影响。结果表明,金玉甜1号春季制种父本比母本迟播18～20 d,父母本花期达到最佳相遇。在父母本花期正常相遇的前提下,金玉甜1号制种母本的最适栽培密度为4.76万株/hm2。Flowering synchronization of the parents of Jinyutian No. ] and effects of plant densities on the yield were studied. The results showed that the florescence differences of the parents was the smallest in spring seeding if 18 -20 d earlier sowing of female parent Huazhen was set up. And the best planting density of female parent in Jinyutian No. 1 seed production was 47,600 per hectare, based on prerequisite of excellent synchronization of flowering between parents.
