Abstract
Over the last 50 years, collection, conservation, identification and utilization of Chinese jujube (Ziziphus jujuba Mill.) germplasm have made tremendous achievements.
Through analysis on their status and problems, the future research directions were proposed.
National Chinese jujube germplasm repository has been established in China, and there are two species and four varieties including 530 varieties and types in it.
A number of excellent or specific germplasm resources have been selected by identifying and evaluating of botany, biology and the main economic traits of over 400 accessions.
In addition, molecular marker techniques such as RAPD and AFLP have been also applied in jujube identification, classification and the study of the origin and evolution.
The formulation and improvement of descriptors and data standards for jujube, the establishment of a database system and the realization of network information sharing have been achieved.
Up to now, over 40 new cultivars have been registered or recognized through strain selection systematically.
Collection and conservation of rare and endangered germplasm and identification and evaluation of germplasm with high resistance and nutrition characters should be strengthened and emphasized.
Physiology, biochemistry, heredity and breeding techniques should be studied thoroughly.
The germplasm management system, the network information platform construction and the germplasm utilization system will be perfected, so as to improve the efficiency of utilization.
