为了研究西北地区气候条件正常年份下芝麻的天然异交率，以单花芝麻品种汾黑芝3号和三花芝麻品种晋芝3号为材料，以显性基因控制的单花芝麻为异源花粉，采用单花和三花芝麻混合播种、在三花芝麻中间单株播种三花芝麻、与单花芝麻不同距离播种3种试验设计，测定三花天然异交后代群体中的单花性状比率。结果表明，混合播种异交率较高，最高达到18.71%，是所有试验设计中最高的。单株播种设计异交率低于混合播种，但高于除第2行外所有不同行距离播种；三花芝麻种植在距离单花芝麻较近，且周边单花芝麻较多的环境下异交率较高，以第2行的异交率最高，达到11.56%；距离单花芝麻远且周边单花芝麻较少的环境下异交率较低，第42~69行的异交率仅有0~0.25%。

In order to study the nature outcrossing rate of sesame (normal year)in the northwest region of China,using a single-flower sesame Fenheizhi 3 and three-flower sesame Jinzhi 3 as materials,using single-flower sesame as heterogenous pollen controlled by dominant gene,three-flower sesame controlled by the recessive gene,three-flower trait became into single-flower trait after natural outcrossing,determining the principle of sesame natural outcrossing rate by measuring the rate of single-flower traits among the progenies(F1)of three-flower sesame;using the experiment design,namely,conducting the mixed seeding with single-flower& three-flower sesame,sowing one three-flower sesame (the spacing is different from the single-flower sesame)among three-flower sesames. The result shows that outcrossing rate of the mixed seeding is the highest of all trials,up to 18.71%. The outcrossing rate of seeds per plant is lower than mixed seeding and higher than different distance sowing;Three-flower sesame outcrossing rate is higher,when they nearing and surrounding of single flower sesame. Ju 2 outcrossing rate is highest,up to 11.56%,On the contrary,the outcrossing rate is lower. ju 42~ju 69 only 0~0.25%.
