摘要
Sugarcane bacilliform virus(SCBV) was detected by PCR from sugarcane showing chlorosis and mottle symptom from Kaiyuan,Yunnan Province.Part sequence of replicase gene of the isolate SCBV-Kaiyuan was determined.Sequence analysis indicated that the 589 bp of SCBV-Kaiyuan shared identities of 73.2%-74.0% and 83.1%-84.1% at nucleotide and amino acid levels with SCBV-Australia respectively,66.7%-68.4% and 65.6%-67.7% with SCBV-Morocco.The quality and yield of the sugarcane infected with SCBV-Kaiyuan was also investigated.The juice extraction,sucrose content,gravity purity and average stalk weight were decreased 1.55%,1.24%,2.22% and 0.26 kg in plants infected with SCBV-Kaiyuan,but reducing sugar was increased by 0.21% in infected plants.
