摘　　要：通过不同播期试验，研究赣油14号播期与群体产量结构的关系。结果表明：在江西宜春，赣油14号的最佳播期为10月6日，适宜播期为9月29日。10月13日，产量可达1792．5—1929．8kg／hm^2；随着播期的推迟，产量表现为先增后减，变异系数为10．2；在产量结构3因子中，单株有效角果数对产量影响最大，变异系数达13．7；其次是千粒重，变异系数为4．45％；每角粒数对产量影响最小，变异系数为1．42。This experiment in different sowir, g date of Ganyou 14 was carried out to research the effect of sowing date on the yield and yield components. The result was as follows： the best sowing date of Ganyou 14 was October 6 and the proper sowing date was from September 29 to October 13 in Yichun city. When Gonyou 14 was sown in proper date, it had higher yield （1 792.5 - 1 929.8 kg/hm^2） .As sowing date was postponed, yield increased ftrsfly and then decresed. Yield components showed that number of pods per plant had the greatest effect on the yield,1 000-seeds weight was second, seed per pod had little effect on the yield.
