太白贝母主要农艺性状的灰色关联度分析

Grey Correlation Analysis of Fritillaria Taipaiensis Main Agronomic Traits

[目的]评价影响太白贝母产量的主要农艺性状。[方法]采用DPS数据处理系统,对15份太白贝母种质资源6个主要农艺性状进行相关分析、灰色关联度分析,探明影响太白贝母产量相关性状间的相互关系。[结果]6个农艺性状的变异系数的范围为10.74%~43.50%;相关分析表明鳞茎高、鳞茎直径与单株产量呈显著正相关;灰色关联度分析获知太白贝母农艺性状与单株产量的关联度排序为鳞茎高>鳞茎直径>地上部分质量>株高>茎粗。[结论]太白贝母产量的关键因素是鳞茎高和鳞茎直径,提高太白贝母的产量可以优先考虑这2种参数的优势。

[Objective]To evaluate the main agronomic characters affecting Fritillaria taipaiensis yield.[Methods]Correlation analysis and grey correlation analysis were carried out for 6 main agronomic traits of Fritillaria taipaiensis cultivars by using DPS data processing system to explore the correlation among Fritillaria taipaiensis yield correlation traits.[Results]The coefficient of variation of the six characters ranged from 10.74%to 43.50%.Correlation analysis showed that bulb height and diameter were significantly positively correlated with yield per plant.Grey correlation analysis showed that the correlation degree between main agronomic characters and Fritillaria taipaiensis yield was bulb height>bulb diameter>aboveground fresh weight>plant height>stem diameter.[Conclusion]Bulb height and bulb diameter are the key factors for the yield of Fritillaria taipaiensis.The advantages of these two parameters can be given priority to improve the yield of Fritillaria taipaiensis.
