The experiment was laid out in a randomized complete block design with three replicates across all sites and seasons. The results showed that the marketable yield of VNUA141 average three seasons reached 11.11 tons/ha, significantly higher than check variety Fancylll (10.85 tons/ha). The average marketable yield over three seasons of VNUA69 variety reached 12.72 tons/ha, significantly higher than check variety HN88 (11.76 tons/ha). Average three seasons, VNUA141 variety had economic benefit reached 35.27 million VND/ha, significantly higher than Fancylll (30.40 million VND/ha). The VNUA69 variety had an average economic benefit of all three seasons reached 42.94 million VND/ha, significantly higher than HN88 (37.75 million VND/ha). The AMMI model showed that variety, season, and the interaction between variety x season had a significant impact on the marketable yield. The effect of variety accounts for a larger proportion of the sum of squares of the variance than the effect of season and the interaction between variety x season. The economic benefit of a com variety depends largely on the season and then on the variety. VNUA141 and VNUA69 varieties exhibited stable marketable yield potential and economic efficiency at all experimental sites and seasons in Hai Duong, showing the superiority of domestic waxy corn varieties with high stability and adaptability.Thí nghiệm được thiết kế theo khối ngẫu nhiên đầy đủ với ba lần nhắc lại trên tất cả các điểm và thời vụ.
