摘要:

【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 significantly 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 positive 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.
