云南布朗族地区作物遗传资源调查

[目的]了解云南布朗族地区作物遗传资源基本现状,促进该地区作物遗传资源可持续利用与生态保护.[方法]采用人物访谈、入户调查和标本采集等调查方法,对云南布朗族地区22个布朗族村的作物遗传资源进行调查研究.[结果]收集了粮食作物、蔬菜、果树、油料作物、经济作物和药用植物等种质资源样本共290份,分属于55科97属113种.其中粮食作物资源115份,分属于7科17属19种;蔬菜(野菜)资源95份,分属于21科33属40种;果树资源35份,分属于23科28属31种;其他植物资源共45份,分属于19科22属24种.[建议]布朗族地区作物遗传资源丰富,应进一步广泛收集种质,提高资源保存数量和质量;加强作物遗传资源的开发利用,对经济性状优良的品种应加以推广.

Investigations on crop genetic resources in Bulang nationality zone of Yunan

[Objective]The status of crop genetic resources was investigated in Bulang nationality zone of Yunan to facilitate sustainable application and ecological protection of crop genetic resources in this area.[Method]Personal interviews,household surveys and specimen collection were employed to investigate the crop genetic resources in 22 Bulang villages.[Result]Total 290 samples were collected including food crops,vegetables,fruit trees,oil crops,economic crops and medicinal plants belonging to 55 families,97 genus and 113 species.To be more specific,there were 115 food crop specimens under 7 families,17 genus and 19 species;95 vegetable(wild vegetable) specimens under 21 families,33 genus and 40 species;35 fruit trees under 23 families,28 genus and 31 species;45 samples of other plants under 19 families,22 genus and 24 species.[Conclusion]Bulang nationality zone had abundant crop genetic resources,therefore,more efforts should be made to collect and exploit these genetic resources.More importantly,superior varieties with outstanding economic traits should be screened out and promoted for commercial cultivation.
