The evaluation of sixteen diverse genotypes including 14 open-pollinated seedling selections of parent cultivars 'Riana' and 'Serena' was conducted for two years 2019–2021 under sub-temperate conditions of western Himalayas. The study was aimed at assessing the genetic variability among the diverse genotypes of alstroemeria. Characters such as umbel: (length of branches), flower: (length of pedicel) and weight of cut stem exhibited high genotypic coefficient of variability. All sixteen parameters recorded high heritability estimates. Traits such as plant height, length of cut stem, number of days taken to bud formation, weight of cut stem and number of days taken to flowering demonstrated high heritability and genetic advance. Positive phenotypic correlations were observed between yield characters and traits such as leaf length, length of cut stem, umbel: number of branches, flower size, and stem thickness. Characters such as weight of cut stem, leaf length, flower: length of pedicel, vase life, leaf width, flower size, number of days taken to bud formation, stem thickness, length of cut stem, number of days taken to flowering and umbel: length of branches showed a positive direct effect on the number of flowering shoots per plant.
