| 摘 要： | 通过2009～2012年的多年多点金早09直播稻示范方的建立,金早09的高产潜力以及适应不利气候环境的能力得到了充分体现,通过相关和通径分析表明:有效穗对金早09直播稻的产量贡献最大,穗实粒数次之。线性回归分析表明:金早09直播稻产量达7500 kg/hm2以上,有效穗、穗实粒数2个性状在95%的置信区间分别为(349.82±8.36)万/hm2、(101.32±3.17)粒,这将为金早09直播稻高产群体结构的搭建提供有力依据。

| Abstract: | The high-yielding potential and adversity resistance of direct-seeding Jinzao 09 have been fully proved through the multi-year and multi-point demonstration during 2009~2012.It indicated that the effective spikes had the largest contribution to the yield,and followed by the filled grains per spike according to correlation and path analysis.Linear regression analysis results showed that: when the yield was more than 7500 kg/hm2,the effective spikes and filled grains per spike in 95% confidence interval were(349.82±8.36) ×104/hm2 and(101.32±3.17) grains,respectively.This could provide a strong basis for its construction of high-yielding population. |
