Classification of Alfalfa McfS^it, Virus Strains Using Microcomputer
Li Yi Wei Ningsheng Zhang Wengjun (.Deportment of Plant Protection')
This paper deals with the classification of Alfalfa Mosaic Virus (AMV) strains by using main element analysis and fuzzy clustering method by means of microcomputer. The results show that H-10 isolate, is completely the same as typical AMV strains and We isolate is very close to yellow patch strain, but it is an independent strain. All these results are confirmed by serological method and partly by the method of analizising amino acids (AA) composition of virus coat protein.
