为筛选出适宜湖北地区种植的全株青贮玉米品种,采用随机区组设计,对14个青贮玉米品种的适应性、抗逆性、生物学产量和粗蛋白等指标进行研究.结果表明,明饲1号和花单1号生育期相对较长,其余品种在92～95天之间.大部分品种的株高在200cm以上;除华丰3号倒伏率较高外,其余品种几无倒伏;收获时,雅玉8号保绿度较其它品种相对较高.参试材料中,8493的鲜草和干物质产量分别为81177.85kg/hm2和20044.37kg/hm2,均显著高于其它品种(p<0.05),而粗蛋白含量最高的是雅玉8号,达9.56％.对主要农艺性状、产量和品质指标进行主成分分析提取了3个主成分,累计贡献率达86.765％.结合各指标的相关性分析,选择单穗重、干物质产量和株高3指标采用模糊数学隶属函数法进行综合评价,结果发现雅玉8号的隶属函数值最高,为0.78,其次为华玉5号,农大86表现最差.
