Optimizing the Production of True Shallot Seed by Inducing Flowering in Various Shallot Genotypes

The study investigated the impact of flowering induction on various shallot genotypes to enhance true shallot seed (TSS) production. Using a randomized complete block design, the research focused on the effects of vernalization and gibberellin (GA3) treatments. Results showed that vernalization significantly increased flowering in the Bauji, Bima Brebes, and Tajuk genotypes, while the combination of vernalization and GA3 was effective for the Maja Cipanas genotype. The Bima Brebes genotype had the highest pollen viability with these treatments. Vernalization also increased TSS weight, suggesting it as a viable strategy for improving TSS production in highland areas. Positive correlations were found between TSS weight and traits like flowering percentage, umbel characteristics, and pollen viability, supporting the development of high-yielding shallot varieties.
