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。
In order to breed alfalfa(Medicago sativa)varieties with high yield,low transpiration and drought resistance,‘Wugong’,‘Sanditi’,‘Sardi10’,‘Longnan No.1’,‘WL168HQ’,‘WL343HQ’,‘WL656HQ’,‘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.
