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。
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.
