Abstract

This paper deals with strategies for agrobiodiversity conservation and promotion based on studies on four plant groups (selected from 50 plant groups) occurring in the Yunnan Province of China. These plants are edible konjac (Amorphophallus), medicinal Paris, Musella lasiocarpa and wild tea (Camellia sinensis and its wild relatives), including their cultivars and wild populations. After analyzing the target plants, we conclude that the following strategies should be adopted to conserve and promote agrobiodiversity: (1) in situ conservation of agrobiodiversity, including habitat protection of wild populations, maintenance of native species and varieties in traditional agroecosystems, and relevant environmental education; (2) ex situ conservation and promotion of agrobiodiversity, including establishment of living collections and germplasm banks, and introduction of species and varieties into agroecosystems for agricultural practice; and (3) promotion and conservation of agrobiodiversity through sustainable uses, including technique development of propagation, cultivation, pest and disease control, on farm and off farm management, and other activities such as new variety breeding and scientific studies. Strategies developed here will be helpful to conserve and promote agrobiodiversity at agroecosystem, species, variety or landrace, and management system levels.
