摘要

Palmarosa是一种重要的多年生芳香草，主要因其富含香叶醇的高价值精油而被栽培。全球对棕榈籽精油的需求不断增长，而喜马拉雅西北部地区适宜品种的供应有限，这突出了对其生产至关重要的优质种植材料的需求。因此，本研究利用25个棕榈草基因型对12个性状进行了评估，利用AMMI（加性主效应和乘法相互作用）和基于WAAS（绝对分数加权平均）的BLUP（最佳线性无偏预测）来估计基因型、环境及其相互作用在四个季节（2019-23）的影响。结果表明，基因型× 对大部分性状有显著的环境互作效应。精油鉴定鉴定出以香叶醇为主要成分的6种主要化合物。关联研究表明，其与香芹烯、月桂烯呈显著正相关，与香樟、丁香、l -芳樟醇和(E)-石竹烯呈显著负相关。单株分蘖数、每茎叶数、花头长度、花头分枝、单株生物产量和精油含量的变异性较高，表明它们有潜力作为较高遗传收益的选择标准。综合平均生产性能、AMMI、WAAS以及环境分析的基因型和基因型，G1、G2和G4基因型最稳定，性状性能和香叶醇含量较高。基于多性状基因型-理想型距离指数，将基因型排序为G2、G1、G4、G14和G8。因此，这些基因型可以优先提高富含香叶醇的精油产量，满足对优质种植材料日益增长的需求。

WAAS-based stability analysis and identification of elite palmarosa (Cymbopogon martinii [Roxb.] Wats. var. motia Burk.) lines using multi-trait genotype-ideotype distance index for higher biomass and essential oil in the North-Western Himalayas

Palmarosa is an important aromatic perennial grass mainly cultivated for its high-value geraniol-rich essential oil. The growing global demand for palmarosa essential oil and the limited availability of suitable cultivars in the North-Western Himalayan region highlight the need of superior planting material crucial for its production. Hence, the present endeavour was led using 25 palmarosa genotypes evaluated for 12 traits to estimate the effects of genotype, environment and their interaction across four seasons (2019–23) using AMMI (additive main effects and multiplicative interaction) and BLUP (best linear unbiased prediction) based on WAAS (weighted average of absolute scores). Results from the study showed significant genotype × environment interaction effects for most of the traits evaluated. Essential oil characterization identified 6 major compounds with geraniol being the dominant constituent. Association studies showed its significant positive association with ocimene and myrcene while negative association with geranial, neral, L-linalool and (E)-caryophyllene. Higher variability estimates for tillers per plant, number of leaves per stem, flower head length, flower head branches, biological yield per plant and essential oil content demonstrated their potential utilization as selection criteria for higher genetic gains. Based on mean performance, AMMI, WAAS, and genotype and genotype by environment analysis, genotypes G1, G2 and G4 were identified as the most stable with high trait performance and geraniol content. Also, based on multi-trait genotype-ideotype distance index, genotypes were ranked as G2, G1, G4, G14 and G8. Hence, these genotypes can be prioritized to enhance geraniol-rich essential oil production and meet the growing demand for quality planting material.
