25份苜蓿材料在淮河中下游地区产量相关性状比较

Analysis of traits related with yield of 25 alfalfamaterials in the middle and lower reachesof Huaihe River

摘要:

选取25份苜蓿属材料在淮河中下游地区进行产量相关性状比较分析,结果表明:苜蓿属不同材料和茬次均显著影响株高、主茎节数、鲜草和干草产量。野生黄花苜蓿株高,主茎节数最多,其次为WL903与WL712,鲜草和干草产量最高的分别是BaraH416wet和巨能551。苜蓿的鲜草和干草产量与株高和主茎节数呈极显著正相关关系,偏相关分析表明控制主茎节数,株高仍与草产量呈正相关关系。野生黄花苜蓿具有最高的株高和主茎节数。

Abstract:

The traits related with yield of 25 alfalfa varieties was conducted in the middle and lower reachesof Huaihe River.The results showed that alfalfa varieties and stubble could significantly affected plant height,nodes of main stem,yield of fresh forage and hay.The plant height and nodes of main stem of Medicago falcataL.were highest,followed by WL903 and WL712.The highest yield of fresh forage and hay were BaraH416wetand Magna551,respectively.The yield of fresh forage and hay had a significant positive correlation with plantheight and nodes of main stem in alfalfa.Partial correlation analysis showed that plant height was still positivelycorrelated with forage yield controlling nodes of main stem.The wild alfalfa has the highest plant height andnodes of main stem,which indicates that the wild variety has the value of breeding.
