Abstract:This paper describes a new type of fresh corn-sweet waxy corn and the representative varieties. Through the innovation and improvement of waxy corn germplasm, all the grains of the fresh corn-sweet waxy corn are waxy with 12%brix or higher on average sugar content during the suitable harvesting period, which is significantly higher than that of ordinary waxy corn. The sweet waxy corn is sweet and forms a special taste quality of "waxy with sweet". In 2011, fresh corn innovation team of Beijing Academy of Agriculture and Forestry Sciences initiated the program of "sweet waxy" germplasm innovation and variety cultivation. Using innovative and integrated breeding methods such as "high-quality, large-group, strict-selection", "individual plant test", and "elite lines aggregation", and a large number of field phenotype identification and evaluation of grain sugar content and taste quality, we produced the waxy corn backbone inbred line ZN3. Using ZN3 as parent, a sweet waxy corn variety Jingkenuo768 was released with 14%brix on the sugar content of fresh kernels. Jingkenuo768 shows the overall advantage, such as high sweetness in kernels, good taste quality, high and stable yield, multi-resistance and wide adaptability, long harvest periods, etc., and has been rated in list of "Top Ten Excellent Variety in China". Jingkenuo768 passed the national examination at four ecological zones in 2021, suitable for planting in the national fresh corn ecological zones. The sweet waxy corn will lead the direction of waxy corn development in the future.
