Abstract:

This paper defines the connotation of ideal type of rapeseed (Brassica napus) plant and emphasizes the multi-functionality of rapeseed and the functional specificity of its ideal type of plant. The ideal type of rapeseed is defined as the plant form that realizes some function of rapeseed and facilitates the maximization of relevant economic benefits. The relationship between the two dimensions of plant type per plant and population was clarified. The basic context of research on the type of rapeseed plants was combed, and four stages of research on the types of ideal rapeseeds were introduced, including the primary, mature, digital and molecular biotechnology stages. An index system of the types of rapeseed plants was constructed, including the roots, stems, leaves, branches, flowers, pods and canopy structure. These structures were summarized and examined by morphometry, summarization of the experiment, experimental statistics, digital simulation, cultivation regulation and genetic improvements in plant type. A classification of the basic principles for research on the types of rape plants was proposed, including those of photosynthetic efficiency, morphological structure, source-sink-flow, and principles of crop physiology. The characteristics and connotation of four typical types of ideal rapeseed based on high grain yield, mechanical direct seeding, vegetable or forage, and ornamental properties were introduced. The shortcomings in the study of rapeseed plant types were analyzed, the basic characteristics, construction strategies and the research trend of ideal type of rapeseed plant were discussed and proposed.

Key words: rapeseed, ideal plant type, high yield, mechanical direct seeding, vegetable-use, forage-use, ornamental properties
