Abstract
結果顯示較抗蟎害品種，計有臺中秈育229號、嘉農秈11號、嘉農秈育13號、高雄選1號、豐錦、轟早生、Mutsunishiki等七品種。稻細蟎蟲口數與稔實率呈負相關，與穀殼褐變率，葉鞘褐變率，主梗扭曲率均呈正相關。 Forty five rice varieties/lines were tested in the second crop of 1979 and 29 varieti es/lines were tested in the second crop of 1980 for their responses to tarsonemid mite. Seven varieties, i. e., Taichung sen 229, Chianung sen 11, Chianung sen yu 13, Kaohsi ung S. 1, Toyonishiki, Todorokiwase and Mutsunishiki were considered resistant to the infection of mites. There was a negative correlation between the percentage of filled grain and mite population per plant. Positive correlations were observed between mite population and the percentage of hull browning, sheath browning and the degree of twi sted panicle axis.
