| Abstract: | ‘Jingketian 179’ is a new fruit-vegetable type sweet corn variety developed by crossing‘ T68’ as
female parent and‘ T8867’ as male parent．The plant is of flat shape with strong growth vigor．It has cylindric
ears with equal size．Its ear is 18-20 cm in length and 4.5-4.9 cm in diameter．There are yellow-white kernels on
the same ear．Its average yield is 12-15 t·hm-2．The growth period is 82 days for spring sowing，and the soluble
sugar，reducing sugar contents，and residue rate in fresh kernels are 33.6%，9.9%，4.5%， respectively．The
growth period is 72 days for summer sowing．The soluble sugar，reducing sugar contents，and residue rate in
fresh kernels are 23.5%，7.8%，11.2%，respectively．It is suitable for cultivation in Beijing，Hebei，Shanxi，
