近年来我国在作物种质资源的收集、保存、性状鉴定等方面取得了很大成绩。近期工作重点是将收集材料按作物由全国有关单位共同整理,分工繁殖,送国家种质库长期保存,并进行抗病虫、抗逆性和品质鉴定。我国各级种质库应根据任务确定适当规模和条件。考察收集,对国内要着重野生近缘种、我国特有作物和小作物;对国外要着重新作物和特殊优良材料。对重要作物进行起源、分类和保存方法研究,对重要性状进行遗传学、细胞学和生物化学等评价。进一步完善我国作物种质资源工作体系。
In recent years, China has made great achievements in crop germplasm collection, preservation and character identification. Recent work will focus on the collection of crops by the relevant departments of the country collated, the division of labor breeding, sent to the national long-term preservation of gene pool, and resistance to pest, stress resistance and quality identification. China’s gene bank at all levels should be based on the task to determine the appropriate size and conditions. Survey collection, we must focus on the wild relatives, China’s unique crops and small crops; to foreign countries to re-crops and special fine materials. Studies on the origin, classification and conservation of important crops are carried out, and the evaluation of important traits by genetics, cytology and biochemistry. Further improve our crop germplasm resources work system.
