鲁西北生态区夏播绿豆产量及主要农艺性状的比较分析

Comparative analysis of agronomic traits and yield on summer-sowing mung bean in northwestern Shandong province

以27个绿豆品种(系)为研究对象,对鲁西北生态区夏播绿豆的11个农艺性状及产量进行了差异性比较、相关分析和灰色关联度分析。结果表明:绿豆产量与主要农艺性状的变异系数从大到小依次为:主茎分枝数>单株荚数>单株粒重>产量>生育后期>株高>百粒重>生育日数>生育前期>主茎节数>单荚粒数>荚长。产量与单株荚数、单株粒重、生育后期、主茎分枝数、生育日数和单荚粒数呈极显著正相关,与荚长和生育前期呈显著正相关,与百粒重呈极显著负相关。绿豆产量与主要农艺性状的关联度由大到小排序为:单株荚数>单株粒重>生育后期>主茎分枝数>生育日数>单荚粒数>生育前期>荚长>株高>主茎节数>百粒重。在高产绿豆新品种的选育及栽培中,选择单株荚数与主茎分枝数多、单株粒重高和生育后期长的品种是鲁西北生态区夏播绿豆获得高产的重要途径。

Abstract:Based on the data statistical analysis,correlation analysis and grey relational analysis method,27 varieties were used to explore the correlation of agronomic traits and yield on mung bean.The results showed that variable coefficient of different traits vary widely,they arrange from big to small as follows:branch number of main stem,pods of per plant,grain weight of per plant,yield,later growth stage,plant height,hundred-seed weight,growth days,earlier growth stage,pitch number of main stem,grain number of per pod,pod length.Test of significance showed that mung bean yield was significantly positively correlated to pods of per plant,grain weight of per plant,later growth stage,branch number of main stem,growth days as well as grain number of per pod these 6 agronomic traits,positively correlated to pod length and earlier growth stage,while it was significantly negatively correlated to hundred-seed weight.The correlation degree of agronomic traits and yield in mung bean from big to small was pods of per plant,grain weight of per plant,later growth stage,branch number of main stem,growth days,grain number of per pod,earlier growth stage,pod length,plant height,pitch number of main stem and hundred-seed weight sequentially.On the whole,in order to generate high-yielding mung bean,plants that having more pods and pitches,higher grain weight and longer later growth stage should be selected,so as to provide more suitable mung bean variety for northwestern Shandong province.
