| Abstract: In order to enrich the cultivar types of mini Chinese cabbage in Liaoning province, six hybrid combinations were obtained by incomplete diallel crossing using yellow heart, miniaturized and root swelling resistant high generation self-incompatibility lines of mini Chinese cabbage as parents, and the main agronomic traits and yield traits of different hybrid combinations were investigated. The results showed that the growth vigor of C2 combination was stronger, the growth rate was faster, and the plant height, plant width, leaf length and leaf width reached the expected value. The leaf sphere width and height of C3 combination were the maximum, of which was 36.73 cm and 55.63 cm, respectively, and the weight of single plant and plot yield were the maximum, and the compactness was the best. The average yield per plot of C2 and C3 combinations were 32.75 kg and 33.78 kg, respectively, and the comprehensive characters and yield were excellent, which was a good hybrid combination. It was preliminarily judged that these two combinations had application value and were worthy of further study and utilization. |
