摘要
为加强优良青饲甜高粱品种在贵州的推广利用,特引进当前生产中几个甜高粱品种(系)进行试验,结果表明,维多45的穗长最长(33.5 cm),较其它参试品种差异呈极显著水平。大力士的主要产量性状明显优于其它参试品种(系),其差异显著性比较明显。株高达470.0 cm,茎粗和节数分别为2.3 cm和20节;穗粒数、穗粒重、千粒重和鲜草产量均明显优于其它参试品种(系),分别为2 894粒、81.6 g、28.2 g和120 833.3 kg/hm2,差异性呈极显著;籽粒产量最高的是晋草1号(7 662.5 kg/hm2),较其它参试品种(系)差异呈极显著水平。
10 introduced forage sweet sorghum varieties （lines） were tested to select the suitable varieties for popularization in Guizhou. The results showed that there was significant difference or very significant difference in main yield characters between Dalishi variety and other tested varieties, and its plant height, stem diameter, internode number, grain number per ear, grain weight per ear, 1000-grain weight and fresh grass yield were 470.0 cm, 2.3 cm, 20, 2894, 81.6 g, 28.2 g and 120833.3 kg/ha respectively. The most ear length of Weiduo 45 was 33.5 cm and the highest seed yield （7662.5 kg/ha） was Jincao 1.
