苜蓿是界上栽培最广泛、最重要的多年生优质豆科牧草,有“牧草之王”的美誉,为了进一步探究苜蓿各生物学性状对苜蓿综合生产性能的影响,选育出适合与不育系MS-GN杂交的苜蓿品种,试验采用灰色关联度分析方法对15个苜蓿杂交组合F1代的主要产量和品质性状等进行了灰色关联度分析.结果表明,对苜蓿综合生产价值影响最大的因子是单株分枝数、干鲜比和粗蛋白,组合朝阳苜蓿×MS-GN综合生产性能最优,适宜在该地区大范围种植,其次为组合Magna-601×MS-GN、金字塔×MS-GN、公农3号×MS-GN、霍普兰德×MS-GN,组合俄7×MS-GN综合排名最后,综合生产性能最差.

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2
