Maternal form
A plant used as the female parent in hybridization to produce seeds with specific desired traits or hybrid vigor.

The maternal form acts as the biological host that nurtures the developing embryo. In commercial seed production, selecting a high-performing maternal line is crucial as it significantly influences seed size, vigor, and potential yield.
During the hybridization process, practitioners must carefully remove the anthers from the maternal flowers to prevent self-pollination. This is often followed by controlled hand-pollination using pollen from a selected male parent.
A common error is failing to maintain rigorous isolation distances, leading to pollen contamination from nearby crops. Furthermore, neglecting the nutritional status of the maternal plant during seed maturation often results in reduced seed quality and poor field emergence.
