20份新编目入国家烟草种质库的烤烟种质的鉴定和分析

为将20份新收集（引进）、选育的烤烟种质资源入国家种质库进行编目和保存，对各种质进行田间鉴定评价，结果表明，云烟317、云烟201、云烟202、云烟203、PVH09和RGH51等品种抗或中抗黑胫病、根结线虫病、青枯病、TMV等主要病害中的2种以上，产量适中、品质较好，已经全国烟草品种审定委员会审（认）定，其余种质资源在田间生长正常，白花大金元、江川地方种、大有种和人民六队-15黑胫病较重。田间试验获得了各种质的生育期、形态特征、主要农艺性状、经济性状、原烟外观质量、化学成分和主要病害等数据资料，拍摄了各种质的植株、叶片、花序、花冠和蒴果的照片，按规定上交合格种子并入库保存，获得的资料全部上交给中国农业科学院烟草研究所，用于中国烟草种质资源信息系统和共享平台建设，为丰富国家种质库以及今后持续利用种质资源奠定良好基础。

Identification and Analysis of 20 New Flue-cured Tobacco Germplasm which Catalogue in National Bank of Tobacco Germplasm Resources

This paper is devoted to identification and analysis of 20 new flue-cured tobacco germplasm resources, which have been newly collected, introduced, bred and catalogued in the National Bank of Tobacco Germplasm Resources. The results show that the varieties of Yunyan 317, Yunyan 201, Yunyan 202, Yunyan 203, PVH09 and RGH51, identified by National Committee of Tobacco Variety, have resistance or mid-resistance for more than 2 or more main diseases, such as black shank, tobacco root knot nematode, bacterial wilt, TMV etc., and have moderate yields as well as good quality. Baihuadajunyuan, Jiangchuan Seed, Dayou Seed and Renminliudui-15 have heavy susceptible to black shank. The rest of germplasm resources grow normally in the field. The related data materials, such as period of duration, morphological characteristics, main agronomic traits, leaf face quality, chemical components and main diseases, have been obtained through field experiments, and the photos of plant, leaf, inflorescence, corolla and capsule also been sent to Tobacco Research Institute of China Academy of Agricultural Sciences, so as to make contributions to the construction as well as allocation for National Information System of Tobacco Germplasm, enrich the resources of the National Bank of Tobacco Germplasm Resources, and make the continuous ultilization of germplasm resources for future research works.
