摘　　要：为了对比美国引进的9个紫花苜蓿品种的繁种效果,试验从苜蓿种子产量构成因子的表现及行距对种子产量的影响进行研究,对苜蓿生殖枝数、花序数/生殖枝、荚果数/花序、种子数/荚果、千粒重、种子产量等生物学性状指标进行了测定。结果表明:FRT、D3、TP 3个品种优于其他几个品种;在行距为60 cm时种子产量最高。说明FRT、D3和TP这3个引进品种更适宜作为繁种在宁夏中部干旱带进行栽培扩繁。To compared the effects of 9 induced alfalfa varieties from the United States, the experimental study was perlbrmed based on the performance of the factors of alfalfa yield components and the effect of row spacing on seed yield. The following biological trait indices were deter- mined, iaeloding the number of fertile shoots per unit square meter, number of infloreseenees per fertile shoot, number of pods per inflores- cence, m^rd）er of ~ecds per pod, thousand seed weight and seed yield. The results showed that FRT, 193 and TP alfalfa varieties were better than other altalfa varieties. The highest seed yields were obtained with row spacing of 60 cm. The results indicate that FRT, D3 and TP intro- duced varieties are mere suitable as the varieties of seed breeding for euhivation and expensive breeding in the central arid areas of Ningxia.
