| 摘 要： | 对2003-2011年通过江西省审定早稻品种的产量进行分析。结果表明，通过江西省审定早稻品种的平均产量随着年度推进总体呈上升趋势，平均产量为6．98t／hm^2,变幅为6．04～7．70t／hm^2；杂交早稻产量高于常规早稻；迟熟组平均产量高于早中熟组和优质组；高产品种仅24个，平均产量7．09t／hm^2。在一定范围内，早稻品种的生育期和株高与其单产存在一定的正比关系。

| Abstract: | The yield of the approved early rice varieties in Jiangxi Province from 2003 to 2011 were analyslsed m the paper, lne re- sults indicated that the yield of the early rice varieties tend to increase annually, the average yield was 6.98 t/hm^2, ranged from 6.04 ff hm^2 to 7.70 t/hm^2. The average yield of hybrid early rice combinations was apparently higher than conventional early rice varieties. The average yield of the late-maturing early rice was higher than that of early-medium maturing rice and good-quality early rice. The high yield varieties were only 24, with an average yield of 7.09 t/hm^2. The growth period and plant height of early rice were positively correlated to the yield in a certain range. |
