摘要
品种是影响高粱高产稳产的重要因素,采用灰色关联度分析方法对引进的11个粒用(食用)高粱品种进行了综合评价。结果表明,参试品种各性状的权重大小依次为株高>经济产量>生育期>单穗重>单穗粒重>穗长>千粒重,进行粒用高粱品种引进筛选,应首先考虑株高和经济产量。各参试品种加权关联度大小依次为5379>锦杂110号>辽夏粱2号>龙杂13号>辽夏粱1号>锦杂109号>赤杂101号>2297>龙米粱1号>吉杂158号>济粱1号,综合性状排在前3位的依次为5379、锦杂110号和辽夏粱2号,适于在当地推广应用。
Variety was the main factors affecting the high and stable yield of sorghum.In order to screen grain sorghum varieties in western Liaoning,the comprehensive evaluation of 11 introduced grain sorghum varieties was conducted using grey correlation analysis method.The results showed that the weight of each character of the tested sorghum varieties was plant height>economic yield>growth period>weight per spike>grain weight per spike>spike length>1000-grains weight,when introducing and screening grain sorghum varieties,plant height and economic yieldshould be considered first.The weighted correlation degree of the tested grain sorghum varieties was 5379>Jiza 110>‘Liaoxialiang 2>Longza 13>Liaoxialiang 1>Jiza 109>Chiza 101>2297>Longmiliang 1>Jiza 158>Jliang 1,The top three in comprehensive production performance were 5379,Jiza 110,Liaoxialiang 2.These three varieties are suitable for planting in the area.
