新疆加工番茄病毒病毒原种类及TMV、CMV株系的鉴定

Identification of Main Causal Viruses and TMV, CMV Strains of Processing Tomto in Xinjiang

对１９９１，１９９２和１９９４年采集的４１２份加工番茄病毒病样本的鉴定结果表明，新疆加工番茄主要毒原种类有烟草花叶病毒（ＴＭＶ）、黄瓜花叶病毒（ＣＭＶ）、马铃薯Ｘ病毒（ＰＶＸ）和马铃薯Ｙ病毒（ＰＶＹ），分别为样本数的４０．５％，２４．８％，１４．６％和４．４％。ＴＭＶ主要株系为０株系，占分离物的６５．７％，其次为１株系占３４．３％，没有发现２株系和１．２株系。ＣＭＶ以轻花叶株系为主，占分离物的６６．７％，重花叶株系为次，占３３．３％。

A total of 412 Processing tomato samples (leaves and fruits) associated with viruses collected from several regiones of Xinjiang in 1991, 1992 and 1994 were identidicated. The results of the experiments showed that the main causal viruses of processing tomato in Xinjiang were tobacco mosaic virus (TMV), cucumber mosaic virus (CMV) , potato virus X(PVX) and potato virus Y(PVY) with 40.5%,24.8%,14.6% and 4.4% of incidence respectively. TMV strain 0 occupied 65.7% of the TMV isolates to be the main strain followed by TMV strain 1 (34.3%). TMV strain 2 and strain 1.2 weren't found. The main CMV strain was mild mosaic strain and occupied 66.7% of the CMV isolates followed by severe mosaic strain (33.3%).
