Abstract

Rose scented geranium (Pelargonium graveolens) is one of the most important aromatic plants. Essential oil is rich in citronellol, geraniol and linalool and extensively used in perfumery and cosmetic industries. Eight mutant lines along with check variety Bourbon were tested among four different environments. Two factor analysis of variation revealed considerable significant variation due to genotype and G × E interaction for almost all the traits. The CSIR-IHBT-PG-05 has highest biomass (1195.08 g/plant) and essential oil content (0.20%). Eberhart and Russell model of stability analysis was performed to predict the significant influence of different environments on mutant lines which further revealed that line CSIR-IHBT-PG-05 has stable performance among the four environments studied. The present investigation provides a strong basis for identifying stable genotype and to carry out the process of selection and cultivar development in rose scented geranium.

Conclusion

The primary goal of this study was to identify stable genotype over multi-environments and for that two factor ANOVA and stability analysis had been performed. The traits with significant environment main effect, genotypic main effect and genotype × environment interaction were further allowed for stability analysis. On the basis of stability parameters, the most stable genotype was selected from multi environments. It was concluded that genotype CSIR-IHBT-PG-05 has superior and stable performance for biomass and essential oil over all environment
