Abstract

Abstract: The 18 agronomic traits of 638 Gastrodia elata BI. f. elata were studied, and the coefficient of variation, correlation, factor and path analysis were carried out. The results showed that among the aboveground agronomic traits of Gastrodia elata BI. f. elata, there were high consistency and specificity in stem diameter, perianth tube length, perianth tube width, ovary length, fruit length and fruit width, and the direct positive effects of factor contribution rate and path analysis were also large; among the main agronomic traits in the underground part, the variation coefficient of longitudinal length, transverse length and ring number was small, and had a significant correlation with the fresh weight of the single tuber, and the direct positive effect of factor contribution rate and path analysis was also large. The main agronomic traits mentioned above could be used as the key traits for quality control and variety breeding of Gastrodia elata BI. f. elata from Dejiang.

Key words: Gastrodia elata BI. f. elata, agronomic traits, path analysis, quantitative analysis, Dejiang county
