花生春秋播主要性状表现及其相关性分析

The Performance and Correlative Analysis of Main Characters of Peanut Sown in Spring and Autumn

用福建省目前种植的6个花生品种为试验材料,研究了花生春、秋播主要性状表现及其相关性。结果表明,不同播种季节花生主要性状表现不同,秋播随海拔升高,花生主要性状也发生明显变化。相关和通径分析表明,春播宜选择有效分枝多,果大仁大的品种,如粤油7号和闽花6号等,秋播宜选择荚果大小适中、果饱、出仁率高的品种,如泉花7号和汕油21等,以获得高产。

Six peanut varieties were used to study the main characters performance and correlative analysis in different sowing seasons. The result showed that there were different performance of main characters of peanut sown in different sowing seasons. The main characters of peanut varied with the rise of altitude in autumn season. The result of correlation and path analysis showed that the varieties which have more effective branches and bigger pod should be selected in spring sowing season such as Yueyou No. 7 and Minhua No. 6 etc. Varieties with plump pod and higher shelling percentage should he selected in autumn sowing season, such as Quanhua No. 7 and Shanyou 21 ete, to get higher yield .
