The representative samples were selected from Yuzong 5, and the methods of field planting and indoor measuring were employed for investigation and data processing on 894 plants of Yuzong 5. The results showed that the coefficients of variation about some traits of 894 plants were as follows: ear height (19.9%); panicle weight (35.1%); ear length (18.1%); ear row number (19.7%); number of kernels per row (22.5%); grain weight per panicle (36.3%); ear diameter (11.1%). It was found that there was large variation in these traits for various plants which could represent Yuzong 5 for glutinous variety improvement.
