Abstract

Clary sage is an important aromatic herb that has a high potential for commercial cultivation under the diversified climates of the Western Himalayas. The present study was carried out to understand the performance of genotypes and their interaction with the varied environments prevalent in the Western Himalayas and to identify stable and best-performing genotypes. In the present experiment, ten superior selections were evaluated in four different environments as multi-location trials in a randomized block design with three replications during 2021 and 2022. The pooled analysis of variance revealed significant variations for genotypes, environments, and genotype × environment interaction for all the studied traits. The highest mean performance suggests that Env-1 has the most suitable conditions for clary sage cultivation. The genotypes CSIR-IHBT-SS-07 and CSIR-IHBT-SS-09 were found to be the best performers for fresh inflorescence weight (418.73 g/plant) and essential oil content (428.91 mg/Kg), respectively. The results of Eberhart and Russell’s regression-based model confirm that the genotype CSIR-IHBT-SS-07 is a stable and superior genotype for the economically important traits. Further, the gas-chromatography mass spectroscopic characterization of essential oil disclosed that CSIR-IHBT-SS-07 was unique in terms of the highest sclareol content (23.39–45.17 %) across all the test environments. Genotype + Genotype × Environment biplot analysis confirmed that all the test environments form a single mega-environment. The study is a pioneer in unraveling the stability response of clary sage in Western Himalaya and provides a strong base for the identification of superior genotypes and selection strategy for future genetic improvement programs of clary sage.

在喜马拉雅西部条件下对鼠尾草(Salvia sclarea L.)选育品种的产量和精油性状进行多环境评估
鼠尾草是一种重要的芳香草本植物,在西喜马拉雅山脉多样化的气候条件下具有很高的商业种植潜力。本研究旨在了解基因型的表现及其与喜马拉雅山西部多种环境的相互作用,并确定稳定和表现最佳的基因型。本试验在 2021 年和 2022 年期间,以随机区组设计、三次重复的多地点试验形式,在四个不同环境中对 10 个优良选育品种进行了评估。汇总方差分析显示,基因型、环境和基因型 × 环境交互作用对所有研究性状都有显著差异。最高的平均表现表明,Env-1 具有最适合种植香紫苏的条件。基因型 CSIR-IHBT-SS-07 和 CSIR-IHBT-SS-09 分别在新鲜花序重量(418.73 克/株)和精油含量(428.91 毫克/千克)方面表现最佳。基于 Eberhart 和 Russell 回归模型的结果证实,CSIR-IHBT-SS-07 基因型在重要经济性状方面是一个稳定的优良基因型。此外,精油的气相色谱-质谱分析表明,CSIR-IHBT-SS-07 在所有测试环境中都是独一无二的,它的香紫苏酚含量最高(23.39-45.17%)。基因型 + 基因型 × 环境双图谱分析证实,所有测试环境形成了一个单一的巨型环境。该研究率先揭示了西喜马拉雅山地区香紫苏的稳定性响应,为今后香紫苏遗传改良计划的优良基因型鉴定和选择策略奠定了坚实的基础。
