超级稻新品种田间比较试验

为筛选适合防城港市种植的优质、高产、抗逆性强的超级稻品种，2006年早造引进了7个超级稻品种进行田间比较试验。结果表明，京福优527、Ⅱ优航1号、准两优527三个品种生育性状表现良好，综合抗性好，与对照相比分别增产20．7％、13．1％和13．0％，增产效果达极显著水平，可以进入区域性示范阶段，并可因地制宜推广种植。因京福优527、Ⅱ优航1号两个品种生育期较长，宜作为中稻种植。

Comparison experiment of new super rice varieties

In order to screen for super rice varieties with good grain quality, high-yield and strong resistance, which were suitable for planting in Fangchenggang City, seven super rice varieties were introduced and compared in field experiment in 2006. The results showed that three varieties including Jingfuyou 527, Ⅱ Youhang 1, Zhunliangyou 527 had better performance and comprehensive resistance, the increasing yield of them reached 20.7%, 13.1% and 13.0%, which very significant as compared to the control. Therefore, the three super rice varieties could be carried out in regional demonstration experiment and extended in suitable area. Because of longer growth stage, Jingfuyou 527 and Ⅱ Youhang 1 could be planted as middle rice.
