The first report is made about Hop stunt viroid (HSVd), Australia grapevine viroid (AGVd), Grapevine yellow speckle viroid 1 (GYSVd1) and Grapevine yellow speckle viroid 2 (GYSVd2) in China.
A new viroid was found in grapevine sample, named Chinese grapevine viroid (CGVd), which has less than 90% similarity to GYSVd1 and GYSVd2.
Citrus exocortis viroid (CEVd) was not detected in all the grapevine samples.
Apple scar skin viroid (ASSVd) was detected in apple samples. The sequences of ASSVd Liaoning isolate and Xinjiang isolate have a top similarity with the sequences reported by Puchta.
28 HSVd sequences, 18 GYSVd sequences, 7 CGVd sequences, 8 AGVd sequences, 3 ASSVd sequences, and 5 CBVd1 sequences were deposited into GenBank.
