摘要
【目的】评价花生单粒精播对花生产量的影响,旨在筛选出适合单粒精播的花生品种。【方法】以适合华南区栽培的珍珠豆型花生品种为试验材料,研究单粒精播对花生荚果产量、种仁产量和农艺性状的影响及其相互关系。【结果】除桂花22外,其他6个参试品种的荚果产量和种仁产量均高于对照桂花17,其中粤油45、桂花1026、汕油162,桂花21、柳花1号的荚果产量比对照增产显著,种仁产量柳花1号和桂花771比对照增产显著;育种目标相近的花生品种间相似度较高;产量性状与农艺性状及农艺性状间均存在不同程度的正相关或负相关。【结论】单株生产力高的花生品种更适合单粒精播;粤油45可通过单粒精播获得较高的荚果产量,柳花1号、桂花771、桂花1026可通过单粒精播获得较高的种仁产量,其在广西等地有较大的推广应用前景。
[Objective ]This research evaluated the effect of peanut under single seed precision sowing on peanut yield in order to screen peanut varieties suitable for single seed precision sowing. [ Method ]Using cultivated pearl-bean type peanut varieties suitable for Southern China area growth as testing materials, the effects and interactions between the single seed precision sowing peanut yield, the kernel yield, and main agronomic traits were studied and the single seed precision sowing peanut varieties were screened out. [Result]Except for Guihua 22, the production yield and seed yield of the other 6 varieties were higher than those of the control variety Guihua 17; out of the different varieties, the pod yield of Yueyou 45, Guihua 1026, and Shanyou 162 increased significantly compared to that of the control, the pod yield of Guihua 21 and Liuhua 1 increased slightly compared to that of the control, and the kernel yield of Liuhua 1 and Guihua 771 increased sig- nificantly compared to that of the control. Higher similarity traits were observed from the similar breeding target of peanut varieties. The yield traits and agronomic traits, and different indices of agronomic traits exhibited different degrees of posi- tive or negative correlations. [ Conclusion ]Single seed precision sowing is an economical and high yielding peanut planting technology. The high peanut variety with single productivity was tested to be more suitable for single seed precision sowing. By the single seed precision sowing, Yueyou 45 produced relatively high yield, and Guihua 1, Guihua 771, and Guihua 1026 obtained higher kernel yield; therefore, the single seed precision sowing displayed great application and extension prospect in Guangxi and other applicable locations.
