黔油系列杂交油菜制种技术研究 Ⅳ.黔油14号制种父母本种植方式

Techniques of Seed Production of Hybrid Qianyou in B.napus Ⅳ.The parental planting method of Qianyou 14 for seed production

通过对黔油14号父母本种植方式的研究得出,母本采用宽窄行移栽,父本以2 m的窝距插栽于母本宽行中的制种栽培方式,父本单株蕾花总数最多,母本单株有效角果最高,有效角率和每角粒数较高,制种产量最高,且在不同环境中的变化最小,稳定性好,制种产量较为安全。

The results from studying the parental planting method of Qianyou 14 in seed production showed that the flower bud number per single male plants reached the most and the number of efficient pod per plant, effective pod rate and grains per pod of single female plant were higher, when the female sterile line was transplanted in wide and narrow rows and the male line was interplanted at 2 m hole interval in wide rows of female sterile line, which could attain the highest and stable seed yield.
