福建新育成花生品种主要性状表现及相关性分析

Correlation Analysis on Main Agronomic Characters of New Breeding Peanut Varieties in Fujian

为了筛选出最适合本地推广应用的花生新品种,对福建省新育成的17个花生品种,采用随机区组排列方法进行试验。结果表明,‘泉花551’平均荚果产量4873.5kg/hm2,居参试种首位,比对照‘泉花7号’增产15.58%,增产极显著,比对照增产极显著的品种还有‘莆花4号’、‘福花8号’、‘泉花8号’和‘闽花8号’。对各性状与产量进行相关和通径分析的结果表明:各主要农艺性状与产量存在着不同程度的相关,产量与各性状的相关系数由大到小依次为百仁重、百果重、总分枝数、侧枝长、主茎高、出仁率、单株结果数、公斤果数;各性状对产量的直接贡献从大到小依次为:总分枝数、侧枝长、主茎高、百果重、单株结果数、出仁率、公斤果数、百仁重、结果枝数。

The seventeen new breeding peanut varieties in Fujian were planted in a randomized block-design in Quanzhou City for selecting the variety that was most suitable for local promotion and application, ＇ Quanhua 551＇ ranked first in all the participating varieties with an average pod yield of 4873.5 kg/hm2, which was 15.58% significantly higher than control ＇Quanhua 7＇, the average pod yield of ＇Puhua 4＇, ＇Fuhua 8＇, ＇Quanhua 8＇ and ＇ Minhua 8＇ were also significantly higher than control. We studied the correlation and path analysis on yield and yield component traits. The results showed that, the main agronomic characters were positively correlated with plant productivity, the correlation coefficient, from big to small, was 100-kernel weight, lO0-pod weight, total branches, branch length, stem height, shelling percentage, numbers of pods per plant, pods of one kilogram. Path analysis showed that the direct path coefficient between different traits and plant productivity, from big to small, total branches, branch length, stem height, 100-pod weight, numbers of pods per plant, 100-kernel weight, pods of one kilogram, 100-kernel weight, numbers of pod branches per plant.
