摘　　要：从产量构成要素方面分析了直立型和半蔓生型绿豆品种的典型特征,结果表明两者的表现正好相反,产量构成要素的差异达到极显著水平,直立型品种荚多、荚短、粒小,半蔓生型品种荚少、荚长、粒大,单株荚数与产量呈显著正相关。提出了利用荚长、粒大、品质优良的半蔓生型品种改良现有直立型绿豆品种,创制单株荚数多、荚长、粒大的直立型绿豆新株型的育种方法,并指导育种实践,育成了新株型品种吉绿14。根据其品种特点分析了应用垄上双行栽培模式对产量等的影响,应用垄上双行栽培模式,吉绿14较常规栽培模式增产11.6%。The typical characteristics of erect and semi-erect mung bean varieties were studied by analyzing the yield components.The results showed that the performance of yield components between erect and semi-erect mung bean varieties was opposite and reached extremely significant differences.The erect varieties had the traits with more number of pods per plant,shorter pods,and smaller seeds,however,the semi-erect varieties had the traits with less number of pods per plant,longer pods,and larger seeds.There was a significantly positive relationship between number of pods per plant and yield.In summary,we presented a breeding method of creating new erect plant type with more number of pods per plant,longer pods and larger seeds by utilizing the semi-erect varieties.The new plant type variety Jilv 14 was bred by this method.Moreover,we analyzed the effects on yield of Jilv14 applying cultivation mode of double rows on one ridge,the results showed that the yield of Jilv 14 was increased by 11.6%compared with that of the conventional cultivation mode.
