晋北绿豆主要经济性状对籽粒产量的影响

试验以11个全国绿豆品种为材料,进行主要经济性状对籽粒产量的相关分析。结果表明,单株荚数增多和植株的增高有利于籽粒产量的增加,籽粒产量随着开花至结荚天数的增加而提高,随着一级分枝的增加籽粒产量降低,缩短结荚至成熟天数有利于籽粒产量的增加,籽粒产量与其它性状相关不密切。因此,选择高植株和增加结荚数量是提高籽粒产量的主要途径。通过增加开花至结荚天数,可间接提高籽粒产量,减少结荚至成熟天数和一级分枝数亦可间接提高籽粒产量。适宜晋北地区种植的绿豆品种为郑绿9号、洮9947-6、汾绿豆2号。

Effect of Main Economic Characters on Grain Yield of Mungbean in Northern Shanxi Province

Eleven Varieties of Mung Bean were used in this study to conduct a analysis on main economics characters relevant to grain yields.The results show that:increase of plant pod numbers and improvement of plant height was advantageous to increase of grain yields.Grain yields was improved with increase of days of flowering to bearing pods.Grain yields was reduced with increase numbers of first branchy stem.Reduction of days of bearing pods to ripening was advantageous to increase of grain yields.Betwee grain yields and others characters was small relations.and selecting height plant and increasing numbers of bearing pod was effective ways to improve grain yields.To increase days of flowering to bearing pods could improve grain yields.To reducing days of bearing pods to mature period and numbers of first branchy stem could indirectly improve grain yields.Varieties of mung beans planting in the Jinbei area was suitable for Zhenglv No.9,Tao 9947-6,Fenlvdou No.2.
