- 摘要:
- 为加强绿豆育种性状选择，以绿丰2号、绿丰5号和JLPX02绿豆为试验材料，选用3个浓度的烯效唑进行浸种，采用大田试验，测定供试绿豆的14个农艺性状，应用方差分析、相关性分析和主成分分析方法进行性状的综合评价，研究烯效唑处理下绿豆农艺性状表现的稳定性及各农艺性状间的相互关系。结果表明，分枝数、根重、根瘤数、单株荚数、单株鲜重和单株粒重6个性状在3个品种（系）中均发生大幅度变异，稳定性弱；主茎节数、株高、荚长、单荚粒数、百粒重5个农艺性状的变异系数均较小，稳定性强；百粒重与荚长呈极显著相关，相关系数最大为0.906；产量与分枝、单荚粒数、单株粒重呈显著相关。主成分分析中，第1主成分中，百粒重、荚长、单株荚数为主要反映荚因子指标；第2主成分中，单株鲜重、单株粒重、分枝为主要反映植株因子指标；第3主成分中，根重、侧根数、根瘤数为主要反映根系因子指标；第4主成分中，单荚粒数、产量为主要反映产量因子指标。综上说明，绿豆的分枝、单株荚数、单株粒重、产量、单株鲜重可作为高产材料选择的主要参考性状，百粒重、荚长、主茎节数、单荚粒数可作为高稳定性性状为材料选择提供参考。
- Abstract:
- In order to strengthen the selection of breeding traits for mung beans, three mung bean varieties were soaked with three concentrations of imidazole, using Lüfeng 2, Lüfeng 5, and JLPX02 as experimental materials. Field experiments were conducted to determine 14 agronomic traits,and variance analysis, correlation analysis, and principal component analysis were used to comprehensively evaluate the traits. The stability of the performance of agronomic traits in mung beans under imidazole treatment and the interrelationships between various agronomic traits were studied. The results showed that the six traits of branching, root weight, number of rhizobia, number of pods, single plant fresh weight, and single plant grain weight all showed significant variation and weak stability in the three varieties (lines); The coefficient of variation (CV) of five agronomic traits, including node number, plant height, pod length, number of seeds per pod, and hundred grain weight, was relatively small and stable; There was a highly significant correlation between 100-seed weight and pod length, with a maximum correlation coefficient of 0.906; There was a significant correlation between yield and branching, number of grains per pod, and grain weight per plant. In principal component analysis, 100-seed weight, pod length and pod number were the main indexes reflecting pod factors in the first principal component;In the second principal component, fresh weight per plant, grain weight per plant and branching were the main indicators reflecting plant factors;In the third principal component, root weight, lateral root number and nodule number were the main indexes reflecting root factors;In the fourth principal component, number of grains per pod and yield were the main indexes reflecting yield factors.Branch, pod number, grain weight per plant, yield, fresh weight per plant can be used as the main reference traits for high-yield material selection. In conclusion, 100-seed weight, pod length, knot number and number of grains per pod can be used as high stability characteristics to provide reference for material selection.
