Cotyledon Size
Cotyledon size refers to the diameter and mass of the seed leaves that emerge during germination, observable within 3–7 days after sprouting. Breeders monitor cotyledon development as an early indicator of seedling vigor and genetic expression. Larger cotyledons often correlate with robust germination rates and faster initial growth, while smaller cotyledons may indicate genetic drift, storage stress, or recessive traits. Cotyledon size is heritable and varies significantly across strain families and seed types. Selection for consistent, well-developed cotyledons supports breeding programs targeting reliable establishment in cultivation environments.

Breeders tracking cotyledon size use it as a non-invasive phenotypic marker during early-stage selection. Strains bred for commercial cultivation often show selection pressure toward larger, uniform cotyledons to improve seedling survival and reduce production variability.
