| الوصف: | 【Objective】According to the market's demand for taste-type and fresh-eatable cabbage, more varieties of cabbage with good characters and in line with market supply and demand were selected by using its own germplasm resources.【Method】Using 13 Ougra sterile heading cabbage materials selected by the team as female parents and 10 inbred lines heading cabbage materials (GL14000-14009) as male parents, 14 heading cabbage hybrid combinations were prepared through hybridization, the experiments were compared and screened from the aspects of plant width, outer leaf number, longitudinal diameter, transverse diameter, central column length, yield and disease resistance.【Result】After comparison, GL22-02, GL22-06, GL22-11 and GL22-13 were obtained, and their agrtural traits, quality and yield were better than those of the control Tejia No. 2. All the leaf bulbs were round, and the petiole-leaf ratio was 26.9%, 20.8%, 23.1% and 16.8%. It was better than that of control variety (31.3%). Leaf bulb compactness was 0.76, 0.73, 0.59 and 0.62 g/cm3, which was more than 0.16 g/cm3 higher than that of the control variety. The central column length was less than half of the leaf bulb height, 4.9, 4.3, 4.8 and 4.6 cm, respectively. The moisture contents were 93.22%, 94.17%, 93.75% and 93.61%, protein contents were 1.51%, 1.28%, 1.39% and 1.36%, respectively. The soluble sugar content were 5.61%, 5.69%, 5.56% and 5.84%, respectively, which were 0.14-0.37 percentage point higher than that of the control variety. The crude cellulose content were 0.61%, 0.71%, 0.69% and 0.67%, respectively, which were 0.08-0.18 percentage point lower than that of the control variety. The vitamin C contents were 682.3, 687.1, 699.1 and 682.3 mg/kg, respectively, which were 48.4-65.2 mg/kg higher than the control variety. After edible quality identification, four hybrid materials of heading cabbage were selected, the leaf balls were raw (fresh) to eat, crisp texture, sweet taste. The black rot disease resistance of the composite materials was high (HR), the same as that of the control.The yield was 4.80%, 8.46%, 10.97% and 8.46% higher than that of control Tejia No. 2.【Conclusion】The four composite materials GL22-02, GL22-06, GL22-11 and GL22-13 were selected. They both had agronomic and economic characters, which can be used for production demonstration in large scale. |
