花生品种比较试验及主要性状相关性分析

Comparative test and correlation analysis on main characteristics of new introduced peanut varieties

对新引进的5个花生品种进行品种比较试验,结果表明:泉花551、龙花243、泉花2197三个品种的荚果和籽仁产量极显著或显著高于对照品种泉花646,且综合性状表现好,可以合理选用;莆花1号产量略低,但稳产性和综合性状表现较好,品质较优,可作为食品加工专用品种利用。主要性状与单株生产力的相关分析结果表明,单株饱果数与单株生产力呈显著相关,单株的总分枝数和结果枝数与单株饱果数呈极显著和显著正相关。说明分枝多,尤其是结果枝多,单株总果数、饱果数就多,单株产量就高。

A comparative test was conducted on five new introduced peanut varieties. The result showed that, the pod and grain seed yields of Quanhua551, Longhua243 and Quanhua2197 were very significantly or significantly higher than the CK variety Quanhua646, they also showed excellent comprehensive characteristics, and could be selected for further application. The yield of Puhua No. 1 was slightly lower, but it showed stable yield, better comprehensive characteristics and higher quality, so it could be used as a special variety for food processing. The correlation analysis on main characteristics and the single plant productivity showed that the filled pod number was very significantly correlated with the single plant productivity; total branch number and pod-bearing branch number were very significantly and significantly correlated with the filled pod number in single plant. It means that, the more branch number, especially the pod-bearing branches, the higher single plant produetivity due to its more total grain number and filled pod number in single plant.
