不同品系鸭茅种子生产性能的比较研究

Comparison on Seed Production of Various Orchardgrass

[目的]选出适合重庆渝西地区进行种子生产且种子生产性能高的鸭茅品系。[方法]对目前国内外常见的几个鸭茅品系在重庆渝西地区的种子生产性能、物候期等方面进行观测和研究,选出适合渝西地区进行种子生产的产量高、品质优的鸭茅品系。[结果]鸭茅在渝西地区均具有较好的种子生产性能,其中鸭茅01076的种子产量最高,达到512 kg/hm2,并且该品系的种子发芽势、发芽率及发芽指数是最高的分别达到49%、84%和11。[结论]01076是值得在渝西地区进行大面积的种子生产的鸭茅品系。

[Objective] To find orchardgrass cultivars which have high seed production and can be planted in western Chongqing region.[Method] Seed production and phenophase were compared between several common orchardgrass cultivars（domestic or foreign） in western Chongqing region.A high-yield high-quality orchardgrass line suitable for seed production in western Chongqing region was found.[Result] The orchardgrass in western Chongqing region had excellent seed production performance.Among these cultivars,orchardgrass 01076 had the highest seed production,up to 512 kg/hm2.Its germinability,germination rate and germination index were also highest,49%,84% and 11,respectively.[Conclusion] The orchardgrass 01076 is worth planting in large scale in western Chongqing region for seed production.
