Bulb propagated from true seed shallot (TSS) has a potency to become a good seed bulb. This study aimed to analyze the growth and production of seed bulbs from TSS planted on dry low land in rainy season. The study was conducted from November to December 2014 in Grobogan Regency, Central Java, Indonesia. A group of G0 bulbs, called Trisula and Tuk Tuk varieties, consisting of small bulbs (Ø 1-1.5 cm, weight 2-5 g) and large bulbs (Ø >1.6 cm, weight >7 g) were planted in a-2 factorial RBD with four replications. Variety and bulb size had a significant effect on all components of growth (plant height, number of tillers) and production (number of bulbs, fresh and dry weight of bulb, bulb diameter, and productivity). The small and large size of G0 Trisula seed bulbs have equal quality as seeds source in the lowland area during rainy season with productivity > 20 tons ha −1 and a small percentage of rejected bulbs ( <0.5 % (0.08 tons ha −1 ). Meanwhile, although having high productivity, Tuk Tuk variety had high percentage of rejected bulbs, 34.22% (9.79 tons ha −1 ); so it is unsuitable to be used as seed bulb in the rainy season.
