Abstract: AMMI model has obvious advantages of analyzing the interactions between varieties and locations, and it can described the differences in the stability of varieties and the discriminability of varieties in different locations quantitatively.The prolificacy and yielding stability of four pilots and seven varieties were analyzed for flue-cured tobacco regional trial in Henan province with AMMI model,the result showed that all the mean yield of new varieties tested were higher than control NC89；the variety Y106 and H8190 had high and stable yield with wide adaptability;Y102 had highest yield,but it had a poor stability;The yielding dependability of variety 8182 was better,but it had a poor prolificacy; the variety 8122 and Youxuanyihao had poor prolificacy and yielding dependability;The prolificacy of variety NC89 was poor, and it had a general yield stability.
