Type: article
Abstract: Monopodial orchids are highly valued for their ornamental appeal, longevity, and adaptability. This study aimed to evaluate the genetic variability among selected monopodial orchid genotypes to support breeding programs for development of hybrid varieties. Twelve monopodial orchid varieties, including monogeneric and bigeneric hybrids were evaluated using a Completely Randomized Design (CRD) with twelve treatments and six replications. The selected materials were evaluated by recording observations on their vegetative and floral characters. Various parameters of variability, heritability and expected genetic advance were calculated. The mean and standard errors were worked out as per standard methods and then coefficients of variation were computed. Significant variations were observed among the genotypes, particularly in inflorescence length, flower count, and vase life, with high heritability and genetic advance estimates. These findings highlight the genetic potential of monopodial orchids for hybridization, emphasizing the importance of selecting genetically diverse parents to enhance flower quality, productivity, and stress resistance. This study contributes to the development of novel monopodial orchid hybrids with superior commercial traits for both domestic and international markets.
