In order to understand the effects of high-yield,stable yield,adaptability and yield components on yield of new wheat variety Yunmai 72,the data of two-year regional experiment and 1-year production experiment in Yunnan Province were used to analyze the correlation among three factors of high-yield,stable-yield and yield component of Yunmai 72 by multiple analysis methods. The results showed that Yunmai 72 had high-yield,good stability and wide adaptability. The yield was positively correlated with effective panicles and grains per panicle,but was not correlated with with thousand grain weight. The direct effect of effective panicles on yield was the main factor of high yield. Therefore,Yunmai 72 had a broad application prospect in the production of Yunnan Province.
