【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】 The objective of this study was to evaluate the effects of single sowing of peanut on the yield of peanut, aimed at screening peanut varieties suitable for single sowing. 【Method】 The pea variety peanut cultivated in South China was used as experimental material to study the effect of single grain sowing on peanut pod yield, seed yield and agronomic traits and their correlation. 【Result】 The results showed that in addition to Osmanthus fragrans 22, the pod yield and kernel yield of the other six cultivars were higher than that of the control Osmanthus fragrans 17, including the pod yield of Yueyou 45, Osmanthus fragrans 1026, Shanyou 162, Osmanthus fragrans 21 and Liuhua 1 The yield of seedlings of Liuhua 1 and Osmanthus fragrans 771 were significantly higher than that of the control. The similarities among the peanut varieties with similar breeding objectives were higher. There were positive or negative correlations between yield traits and agronomic traits and agronomic traits Related. 【Conclusion】 Peanut varieties with high single plant productivity are more suitable for single-grain sowing. Yuegyou 45 can achieve higher pod yield by sowing single sowing seeds. Liuhua No.1, Osmanthus fragrans 771 and Osmanthus fragrans 1026 can be obtained by sowing The higher seed yield, which in Guangxi and other places have a larger promotion and application prospects.
