Abstract:
Objective To analyze the genetic difference of biological characters on germplasm resources of fenugreek(Trigonella foenumgraecum) and to study the genetic diversity of them.Methods Thirty-two fenugreek germplasm resources from Ningxia, other provinces in China,and abroad were used to investigate the biological characters on plant height,pod formation height,nodes per main stem,branches number,effective pod per plant and so on.The tested materials were planted in the farm of Ningxia University.The genetic diversity based on the phenotype was analyzed by Word′s minimum variance method.Results The variance analyses of ten biological characters were of significance or the most significance except pod length.The branches number and effective pod per plant possessed the largest coefficient of variance(CV). The pairwise Euclidean distance of the tested materials ranged from 1.11 to 9.49,averaged 4.01.Mean Euclidean distance of single tested material ranged from 2.94 to 6.54.The tested germplasm resources could be divided into three groups in D=6.86,which coincided with the district of collecting germplasm resources on the whole.Conclusion There is a little genetic difference in various fenugreek germplasm resources.Compared with Euclidean distance of germplasm resources from Ningxia,the Euclidean distance of most from abroad is far away from that of other provinces in China.
