摘　　要：通过杂交水稻制种父母本基本苗、厢宽和母本栽插规格对制种产量的影响的试验分析，指出各因子中以父母本基本苗对产量的影响最大，必须采用适当行比，同时增加父母本基本苗数，才能达到制种高产的要求．The experiment of the influence of 4 factors including basic seedlings of the seed parent, basic seedlings of the pollen parent. bed width and spacing of the seed parent on seed yield in the seed production was conducted with Shanyou 63 （Zhenshan 97A ×Minghui 63） as the material. It was found that the basic seedlings of the seed and pollen parents among the 4 factors had the greatest effect on seed yield via the influence on productive panicles and seed-setting rate of the seed parent. In Xinyang of Henan Province, to obtain a high yield in seed production, it is necessary to establish a high yielding population structure by way of adopting the set of techniques with the bed width of 2. 33m, basic seedlings for the pollen parent of 0. 6 mil/ ha, basic seedlings for the seed parent of 3. 75 mil/ha.
