Study on the chemical quality characteristics of self-breeding tobacco germplasm GDH88

Chemical component of main cultivar flue-cured tobacco was carried out among K326,K730,G70,G140,Yun85 and self-breeding germplasm GDH88.The results showed that the content of nicotine in GDH88 was 2.2807%,sugar alkali 8.970,nitrogen alkali 0.9312,schmuck number 1.8924.The reserch indicated that among 13 varieties,the chemical component of GDH88 was the most appropriate.Through analyzing the correlation of the four parents,we found that the high-quality gene of GDH88 was mainly come from the parent K326.The results from the research on the self-breeding tobacco germplasm GDH88 showed it had good coordination and quality.The GDH88 had great potential for application in flue-cured tobacco breeding.
