| The Crops Research Institute of Guangdong Academy of Agricultural Sciences has developed parent
materials GQ-1 and Group 1-1 with far genetic relationship and strong complementarity by the method of combining
population breeding and second cycle inbred line breeding.“Yuetian 28”is a variety of single cross super-sweet corn
with GQ-1 as female parent and Group 1-1 as male parent. This variety was approved by Guangdong Crop Variety
Approval Committee in 2017, by National Southern Region and Huanghuaihai Region Crop Variety Approval Committee
in 2018 and 2020 respectively. It is a sweet corn variety approved by the most areas. In 2015, the variety management
license of“Yuetian 28”was transferred successfully with a transfer fee of 5 million yuan, and it is a sweet corn variety
with the highest transfer fee at present. From 2017 to now,“Yuetian 28”has been rated as the dominant corn variety in Guangdong Province, and has been widely promoted. The regional trial results showed that“Yuetian 28”had obvious yield
advantages, excellent quality and strong lodging resistance. In the two-season trial, the yields were significantly increased
compared with those of the control, ranking No.1 and No.2 in the group respectively. The production in the national regional
trial increased significantly compared with that of the control, with a yield increasing rate of above 62.5%. The palatability
scores evaluated by experts were all superior to those of the control, with the highest score reaching 91.3. The sum of lodging
and foiding rate was between 0-2.4%, which was significantly lower than that of other tested varieties in the same period.
According to the research on cultivation, nutrition, physiology and molecular biology with“Yuetian 28”as the material, the
results showed that the contents of lutein and folacin in the grains of“Yuetian 28”were high, which is an ideal nutritious
sweet corn variety. Therefore,“Yuetian 28”is a new sweet corn variety with high yield, good quality, nutrition and strong
lodging resistance. It has a wide planting area and is suitable for mechanized cultivation management and processing, which
is conducive to large-scale promotion.“Yuetian 28”is not only a breakthrough variety in urgent need of the market but also
an ideal basic research material for sweet corn. |
