Abstract: One hundred and twenty -eight piece of belt signs are multiplied through selecting 12 pairs of associationsform 60 piece of random decoy and multiplying Curvularia lunata randomly.According to the signs,pathogen's mutual relationsare analyzed.The result is that the highest similarity degree of the pathogen is 87 % and the lowest is 47 %.Twenty-two experimental pathogen all gather together by all stems on 0.4 to the stem in the linked together.The pathogenforming tree shape can be divided into 5 or 6 groups.Group a consists of 6 pathogen,they are 98 -36,98 -25,98 -17 ,98 -07,98 -01 and 98 -28 ,which is the most approximate one on heredity base.
