【摘要】 为了选育高产、优质且适宜性较好的扁穗雀麦新品系,对贵州不同生态区域的9份种质材料的物候期、株高、草产量与品质、种子产量进行了比较研究。结果表明:扁穗雀麦不同种质材料在贵州独山都能完成其生育期,不同种质材料间株高、草产量和种子产量等生长性能与粗蛋白、粗纤维等品质存在显著差异,其中,采集于独山县6号和普定县19号扁穗雀麦种质材料的鲜干草产量和种子产量较高且草品质好,适宜作为扁穗雀麦新品种培育和应用的种质材料。更多还原

【Abstract】 For selection new strain of Bromus catharticus with high yield,superior quality and good suitability. The phonological period,plant height,grass yield and quality,seed yield of 9 germplasm materials which collected in Guizhou diverse ecological regions were compared. The results indicated that the various germplasm materials can meet its growth period in Guizhou,there was significant differences in plant height,grass yield and quality,seed yield among 9 germplasm materials. Among them,of collection in dushan and Puding county 6 and 9’s characters were more prominent,which were suitable to be used germplasm materials of Bromus catharticus new variety breeding and application.更多还原
