Abstract: Marigold is mainly cultivated and propagated through seeds and the cultivar identification is the key issue in crop improvement programme because of less variation available in the genotypes. Hence, a study was undertaken to identify the genotypes at various stages of seed crop growth. The experimental results showed that, genotypes can be identify/distinguish at various growth stages with available descriptors and also using additional descriptors as well. Based on seed geometric properties, seed phenotyping was made using image-based machine vision software showed that these seed traits and can be successfully used to distinguish the cultivar seeds and in an attempt made to identify/distinguish two species of marigold (African and French) resulted as a successful approach in establishing alternative varietal identification system.
