- Abstract:
- Twenty-three seedling-edible Chinese cabbage hybrid combinations were used as materials,the main agronomic characteristics affecting the yield per plant were studied with the method of grey correlation degree analysis,in order to provide scientific basis for the seedling-edible Chinese cabbage breeding selection on high yield.The results showed that the maximum leaf petiole thickness,width and leaf width of the agromic characteristics related to yield per plant ranked in the top three.The total order was as follows:maximum leaf petiole thickness>maximum leaf petiole width>maximum leaf width>number leaves when harvesting>maximum leaf stalk length>maximum leaf length>development degree>plant height.The contribution of main agronomic characteristics to yield per plant was clarified.
