绿豆产量构成因素的相关与通径分析

用相关分析系统分析了与绿豆产量有关的12个农艺性状。相关分析结果表明, 分枝数, 单株荚数、单株产量、抗倒性和抗病性与产量呈正相关, 其中单株荚数、单株产量和抗病性达显著或极显著水平; 而株高、主茎节数、荚长、荚宽、百粒重和生育期呈负相关, 其中荚长和生育期达显著或极显著水平。通径分析结果表明, 12个性状对绿豆产量的直接作用依次为单株荚数>抗病性>荚宽>抗倒性>荚长>株高>分枝数>单荚粒数>百粒重>单株产量>生育期>主茎节数。在高产绿豆新品种的选育中, 首先应注重对单株荚数、抗性和生育期的选育, 然后再综合考虑其他性状。

The Correlation Analysis and Path Analysis on Main Characters of Mung Bean

Twelve characters with the yield of Mung Been were studied with the method of correlation analysis and path analysis.The results showed that number of branches per plant, numberof pods per plant,number of grains per pod, yield per Plant,lodging resistance and diease resistance were correlated posivitely with the yield. Among of them, correlation coefficient of numberof branches per plant, numberof pods per plant,yield per plant and diease resistance with yield was significant difference.Plant height, Number of joints of main stem,pod length, pod width, 100-grain weight and growing period was correlated negatively with yield, and the correlation coefficient of pod length and growing period with the yield was signilicantly difference. The results of path analysis showed that the direct effectof twelve characters with the yield was numberof pods per. Plant > diease resistance >pod width>lodging resistance >pod length>plant height> Number of branches per plant>Number of grains per. Pod >100-grain weight>yield per Plant>growing period>numberof joints of main stem. When high yield variety of new Mung Been was selected,the character of Number of pods per plant should be taken into consideration first, the resistance and growing period, then to comprehensively consider the rest of characters.
