棉花新品种丰产性、稳产性及品质的综合评价研究

Studies on the comprehensive assessment of the high yielding、Stability and Goods quality of new cotton varieties

通过聚类分析、稳定性分析以及农业系统工程学原理对不同品种在不同生态点的主要农艺及经济性状进行了分析,结果表明:不同生态点间生产水平存在着极显著差异,品种间也存在极显著差异。从产量性状来看,以安农02—6综合性状表现良好,丰产性和稳产性较强,适合湖南种植;从湖南定位50～60支纱区划方针来看,以湘Z2087表现最好。

By means of cluster analysis,Stability analysis and the agricultural systen project rule analised on main agronomic and economic characters of cotton in different eclology spot.The results showed;Distinct ecology some manufacture levels are exeeedingly marked divergence,Also be exceeding ly marked divergence between the strain.through the yield properties,An Nong02-6 is tall,the high yielding is powerfuler as stability,through Locate 50~s～60~scompartment guiding principle in hunan,xiangZ2087 expresss good.
