Abstract: 'Liketian 5807' was a new cultivar of sweet corn with yellow and white grains, and this sweet corn was crossed by taking inbred line of 'Sweet H-02' as female parent and 'Sweet H-804' white' as male parent. This new cultivar had excellent quality, beautiful spike shape, complete and tight bracts, full, tight and neat grains with the color of yellow and white and no bald tip. The multipoint test in 2013 and 2014 and comparison test of Hefei in 2015 and 2016 were conducted. The results showed that the new hybrid had obvious heterosis, high growth vigor, large fruit spikes, good taste quality and high yield potential. The yields were respectively 1 178.9, 1 061.2 kg per 667 m2, and increased by 9.7%, 10.1% compared with that of the control ('Yuetian 16') in 2013 and 2014. The yields were respectively 1 106.1, 993.0 kg per 667 m2, and increased by 8.2%, 9.5% compared with that of the control ('Yuetian 16') in 2015 and 2016. Field investigation was carried out, showing that 'Liketian 5807' was highly resistant to spot disease, sheath blight and stem rot and had strong resistance to lodging with developed roots, which met the needs of the current market and was suitable for planting in Nanjing and the same ecological areas. |
