Abstract:

This paper summarizes the main breeding models, methods and regionalization of konjac seed taro in China, including breeding models of field, understory, facility and courtyard breeding, breeding methods of using rhizomes or corms, cuttings, plant tissue culture and seed breeding, and 4 main regions and 6 sub-regions of Konjac seed breeding. Based on the review, the paper proposes suggestions including reasonable layout of konjac varieties under different climate conditions, innovative development of economic forest, fruit forest and breeding facilities suitable for interplanting konjac; integrates mountain konjac cultivation techniques to prevent drought and waterlogging, biological diversity and multi-dimensional interplanting technology for weed prevention and control, and konjac - soybean - corn strip interplanting technology. The above results improve and innovate the breeding mode and method of konjac seed taro, and expand the suitable planting area of konjac, in order to promote the development of konjac industry in the mountainous area of southwest China.

Key words: seed taro of konjac, breeding model, breeding method, breeding regionalization
