To further screen and enrich the types of excellent fresh waxy maize varieties, this study conducted a demonstration trial with 18 fresh waxy maize varieties including Heijin 699, Ruihezaonuo, and Shenketiannuo 99 as test materials, comparing and analyzing their growth period, main agronomic traits, ear traits, occurrence of diseases and insect pests, quality, and yield. The results showed that Ruihebainuo 80 germinated 7 days after sowing; it had a plant height of 213.7 cm, with no lodging or stem breaking; the ear length was 20.1 cm, tip barrenness was 0.3 cm, and the fresh 100-grain weight was 35.8 g; the total quality score was 88.8 points, and the yield reached 16 716.7 kg/hm². Shenketiannuo 99 germinated 6 days after sowing; its plant height was 207.5 cm, with a lodging rate of 0.4% and no stem breaking; the ear length was 19.6 cm, tip barrenness was 0.9 cm, and the fresh 100-grain weight was 37.2 g; the total quality score was 88.1 points, and the yield was 14 441.7 kg/hm². Huanaicaitiannuo 102 germinated 6 days after sowing; it had a plant height of 234.1 cm, with a lodging rate of 0.4% and no stem breaking; the ear length was 21.7 cm, tip barrenness was 1.0 cm, and the fresh 100-grain weight was 42.5 g; the total quality score was 87.8 points, and the yield amounted to 16 039.6 kg/hm². Shenbaitiannuo No. 3 germinated 7 days after sowing; its plant height was 196.3 cm, with no lodging or stem breaking; the ear length was 19.3 cm, tip barrenness was 1.1 cm, and the fresh 100-grain weight was 41.0 g; the total quality score was 88.2 points, and the yield was 13 981.3 kg/hm². Huhongnuo No. 1 germinated 6 days after sowing; it had a plant height of 227.3 cm, with no lodging or stem breaking; the ear length was 19.1 cm, no tip barrenness, and the fresh 100-grain weight was 40.5 g; the total quality score was 90.4 points, and the yield reached 14 731.3 kg/hm². Heijin 699 germinated 7 days after sowing; its plant height was 188.1 cm, with no lodging but a stem breaking rate of 1.7%; the ear length was 18.0 cm, tip barrenness was 0.4 cm, the fresh 100-grain weight was 34.7 g, and it had purple kernels; the total quality score was 88.5 points, and the yield was 12 708.3 kg/hm². For all the above varieties, the incidence grade of sheath blight, stem rot and Asian corn borer was grade 1. Comprehensively, Ruihebainuo 80 had an outstanding yield advantage and excellent quality performance; three varieties, namely Huanaicaitiannuo 102, Shenketiannuo 99 and Shenbaitiannuo No. 3, showed good yield and quality, with good comprehensive traits; Huhongnuo No. 1 had relatively high yield, excellent quality and good marketability; although Heijin 699 had no prominent yield advantage, it had a sweet, tender and glutinous taste, good quality and purple kernels, with good commercial appearance. All the 6 above-mentioned varieties had good comprehensive performance and could be promoted for cultivation in the study area.
