In order to systematically understand the characteristics of ploidy,growth period,yield,quality and resistance to pests and diseases of Jingjiang No.1,the methods of chromosome observation in laboratory,field production experiment,resistance monitoring and nutrient composition determina-tion were carried out.The results showed that Jingjiang No.1 was a new Zingiber officinale variety with diploid(2n=2x=22),the growth period was 192 days,the leaf color was dark green,the plant grew strongly,the average plant height was 102.67 cm,the average branch number was 26.10,and the average stem diameter was 1.38 cm.High resistance to ginger blast,non-selective resistance to aphids and mites,strong drought resistance,strong waterlogging-tolerance.The rhizomes were hypertrophic,with fresh weight of 1 241.1 g per rhizomes,zinc content 4.89 mg/kg,selenium content 0.001 5 mg/kg,crude fiber content 0.91％,soluble protein content 1.31 g/100 g,vitamin C content 8.61 mg/100 g,soluble sugar content 0.83％.The content of gingerol was 1.69％,and the spicy taste was moderate.The production test results showed that the average yield was 3 609.1 kg/667 m2.This variety was suitable for Zingiber officinale growing areas in the Yangtze River basin.
