  • Planting ratoon rice can save on labor, fertilizer and seeds resulting in a financial gain for the farmers. In this study, the yield and major economic characteristics of 11 ratoon rice varieties were evaluated using the grey incidence analysis. The results showed that II-Youhang 1 had the highest equal weighed incidence degree (EWID) as well as the weighed incidence degree (WID), and was considered the most desirable variety for rice ratooning among all. Two other varieties selected were Tianyou 3301 and II Youming 86 in that order. The varieties, II You 1273, Guyoumingzhan and Tianyou 673, had higher WIDs than the control (Shanyou 63). They could be used for ratooning as well. On the other hand, the WIDs of Jyouming 62 and Liangyouhang 2 were low, and therefore not recommended for the purpose.
