Comparative Evaluation of 32 Early-Maturing Cauliflower Hybrids

To screen for superior, high-yielding early-maturing cauliflower（Brassica oleracea var. botrytis）hybrids, we systematically evaluated 32 test combinations for their botanical traits, commercial characteristics, and yield performance. The results showed that SHZ23-28, SHZ23-19 and SHZ23-27 exhibited outstanding yield performance, reaching 46177.78 kg·hm⁻², 43600.00 kg·hm⁻² and 42288.89 kg·hm⁻² respectively, which were 35.3%, 27.7% and 23.9% higher than that of the control cultivar CK Qingnong 65. Among them, SHZ23-28 performed excellently in terms of high yield potential, marketability and adaptability.This hybrid cultivar can be harvested approximately 65 days after autumn transplanting. It has strong growth vigor and a relatively erect plant type, with dark green leaves covered in waxy bloom. The curds are high-round, fine-grained and milky white, featuring a semi-loose texture. The pedicels are light green, with the average weight of a single curd being around 1.4 kg.
