| Abstract: |
| 【Objective】The study was performed to select new super-sweet corn resources of fruit type that suitable
for planting under sub-tropical conditions in Guangdong.【Method】Sixty-six new super-sweet corn varieties of fruit
type, introduced from domestic and overseas, were evaluated for 3 years（5 seasons）. Twenty high-quality varieties of
which were selected for comparison test, and the adaptability, resistance, plant characters, ear characters, yield and quality
characters were identified and analyzed.【Result】Results of field observation and indoor test showed that the 20 varieties
were early-maturing and short stem type, characterized by short growth period, good plant uniformity, shorter stem and
lower ear position. The shape was even in the ear head and base, and the size of grains was small to medium. With thin seed
coat, crisp taste, high sugar content and low water content, slow sugar degradation, long shelf life, the fresh ear had the same
sweetness when it was raw or cooked.【Conclusion】The different indexes showed that ten varieties（‘GT-11’,‘Cu
itian’,‘Shengtian1365’,‘Shengtian5590’,‘BMB380’,‘Jingbaitian456’,‘Shengtianbaizhu’,‘Gaobo’,‘
Wanda Bingtang’,‘Baizhenzhu 627’） had higher yield than that of the CK significantly, could be used as the original
materials of inbred lines for breeding with good comprehensive traits. In addition, five varieties including ‘Shengtian5788’,
‘Shengtian169’,‘Kupula’and‘Baimawangzi’,‘Shuang Xi’, with less yield, should be synthesized hybrids with several and separated good strain for utilization. The other varieties that suitable for planting in Guangdong with the least yield
but highest quality, including ‘Zhenzhu’, ‘Baixuegongzhu’, ‘Taiwan Xianlv’and‘Yuebaitian 2’, should be further
improved and utilized through traditional breeding and modern biotechnology. |
