摘要: 研究638株德江红天麻(Gastrodia elata BI. f. elata)的18个农艺性状,并进行变异系数、相关性、因子和通径分析。结果表明,德江红天麻地上部分农艺性状中,花茎粗度、花被筒长度、花被筒宽度、子房长度、果实长度和果实宽度具有较高的一致性和特异性,其因子贡献率和通径分析的正向直接作用也较大;地下部分主要农艺性状中,纵长、横长和环纹数的变异系数较小,与单个块茎鲜重有极为显著的相关性,其因子贡献率和通径分析的正向直接作用也较大。上述主要农艺性状可作为德江红天麻品质控制和品种选育的关键性状指标。

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
