烤烟新品系DL02选育及特征特性研究

Study on the Cultivar Breeding and the Characteristics of the New Cultivar DL02

DL02是大理州烟草公司烟叶技术中心种子站于2002年在弥渡县密址镇的红花大金元示范田中选育出的变异株经多年培育而成的烤烟新品系,与当地主栽品种红花大金元相比,DL02的苗期生长势、大田期生长势、生长整齐度、抗病性、产量、产值、上等烟比例、级指、均价、烘烤特性、色素含量及生理抗性指标等11个方面,均优于亲本红花大金元,显现超亲现象,具有更加优良的特性,值得生产中试用.

The variety of DL02, which was discovered by the technology center of Dali Tobacco seed station in Midu county in 2002, is a variation from the variety of Honghuadajinyuan and it＇s flower is pure white. Compared with Honghuadajinyuan, DL02 would be superior in nine characters, such as growth potential in seedling stage and field stage, growing orderliness, antivirus capability, output, production value, ratio of good grade tobacco, curing character, content of pigment and the variety stability in different stage. Therefore, DL02 is worthy of planting.
