基于灰色关联度分析的河南省麦套花生研究

Peanut Intercropped with Wheat in Henan Province: Grey Correlation Analysis

旨在了解河南省麦套花生育种现状和筛选适宜推广的花生品种。利用灰色系统理论对27个参试花生品种的11个主要性状:主茎高、侧枝长、总分枝、结果枝、单株结果数、百果重、百仁重、出仁率、饱果率、单株生产力、荚果产量进行关联度分析。结果表明:灰色关联度分析能准确判断参试品种优劣,筛选出适宜推广的参试品种;加权关联度值更为真实反映品种的综合表现,19个参试品种的加权关联度值比对照‘豫花15号’大,占参试品种的70%以上,其中‘商花17号’加权关联度值和产量排名第一,表现最好。河南省麦套花生整体育种水平较高,‘商花17号’、‘洛花3016’、‘濮花43号’、‘远杂14号’综合性状和产量表现优良,最适宜在河南省推广种植。

The aim is to understand current status of peanut intercropped with wheat and screen peanut varieties suitable for promotion in Henan Province. The 11 agronomic traits of 27 peanut varieties, including main stem height, lateral branch length, number of total and pod branch, pod numbers per plant, 100-pod weight, 100-seed weight, kernel rate, full pod rate, productivity per plant and pod yield, were analyzed using the grey correlation analysis. The results showed that the grey correlation analysis could accurately appraise the quality of tested varieties and select peanut varieties that were suitable for promotion. The weighted correlation degree values truly reflected the integrated performance of the tested varieties. The weighted correlation degree of 19 tested varieties was larger than that of‘yuhua15’(CK), accounting for more than 70%of the tested varieties. The weighted correlation degree value and pod yield of‘Shanghua17’ranked No. 1, and the performance was the best. The overall level of intercropped peanut is relatively high in Henan. The integrated traits and yield of‘Shanghua17’,‘Luohua3016’,‘Puhua43’and‘Yuanza14’are excellent, which are more suitable for planting in Henan Province.
