| Abstract: In order to select new ginger cultivars with high yield, good quality and disease resistance for
Tangshan area and realize cultivars updating, taking Shandong great ginger as control, comparative experiments
were conducted on six introduced ginger cultivars, including 'Changyi Dajiang' 'Shannong No.1' 'Pangwawa'
'Pingding4' 'Anhui Dajiang' and 'Jiangyong Xiangjiang', as well as self-improved cultivars 'Jijiang No.5' and
breeding line 'DJ09-6'. Through the comparison of plant agronomic traits, rhizomes stem commodity traits,
quality, yield and plant disease resistance, the results showed that 'Jijiang No.5' 'Pingding4' and 'Shannong No.1'
had strong vigorous growth and high yield of 7 294.58, 7 021.42 and 6 865.34 kg per 667 m2
, respectively.
Comprehensive characters of them were good and they were suitable for promotion and planting in Tangshan area.
The yield of breeding line 'DJ09-6' was outstanding, but the population uniformity was worse, which could be
further observed. |
