摘要
本研究以宁杂 1号不育系宁 A6和恢复系宁 R1为材料 ,研究了亲本不同行比配置及同一行比母本不同种植密度对制种产量的影响。结果表明 ,宁杂 1号制种亲本行比以 1∶ 4～6为宜 ;在一定行比条件下 ,母本适宜栽培密度为 (1 5～ 1 8)× 1 0 4 株· hm- 2 ,适当调整父本 ,增加母本种植密度 ,可以确保制种质量 ,提高制种产量。
Taking the sterile line Ning A6 and restorer line R1 as parents resource, the paper studies that different row ratios of parents has great influence on the seed yield of Ningza No.1 and different density of female parent also has influence on seed yield while row ratio is same. The results indicate that the optimum row ratio of male parent to female parent is 1∶4～6; under the condition of definite row ratio, the adapted density of female parent should be (15～18)×10 4 plants·hm -2 ; through adjusting male parent and increasing planting density of female parent, it should be ensured for seed quality and yield.
