【摘要】 为选育低蒸腾的高产抗旱苜蓿（Medicago sativa）品种,本试验以‘武功’、‘三得利’、‘Sardi10’、‘陇南1号’、‘WL168HQ’、‘WL343HQ’、‘WL656HQ’、‘WL712’、‘WL903’进行多父本杂交,并从F₁代选出母本为‘WL903’的WL903-1^#—WL903-7^#和母本为‘Sardi10’的Sardi10-1^#—Sardi10-5^#共12个株系作为试验材料,进行蒸腾特性和产量相关性状分析。结果表明:12个株系隶属函数综合评价顺序为Sardi10-5^#>Sardi10-4^#>WL903-4^#>Sardi10-1^#>WL903-2^#>WL903-1^#>WL903-6^#>WL903-7^#>Sardi10-2^#>WL903-3^#>Sardi10-3^#>WL903-5^#。本研究结果表明,Sardi10-5^#和Sardi10-4^#为低蒸腾、高产的理想株系。更多还原

【Abstract】 In order to breed alfalfa(Medicago sativa) varieties with high yield, low transpiration and drought resistance, ‘Wugong’,‘Sanditi’,‘Sardi10’,‘Longnan No.1’,‘WL168 HQ’,‘WL343 HQ’,‘WL656 HQ’,‘WL712’,and ‘WL903’ were used for multi-parent hybridization in the experiment. A total of 12 strains of WL903-1~#—WL903-7~# with female parent ‘WL903’ and Sardi10-1~#—Sardi10-5~# with female parent ‘Sardi10’ were selected as experimental materials for transpiration characteristics and yield-related traits analysis. The comprehensive evaluation order of the membership function of 12 strains was: Sardi10-5~# > Sardi10-4~# > WL903-4~# > Sardi10-1~# > WL903-2~# > WL903-1~# > WL903-6~# > WL903-7~# > Sardi10-2~# > WL903-3~# > Sardi10-3~# > WL903-5~#. The results showed that Sardi10-5~# and Sardi10-4~# were ideal strains with low transpiration and high yield.更多还原
