Abstract: The study aims to understand the production situation of new wheat varieties bred in south HuangHuai region and promoted by Henan Province in recent 10 years, and reveal the effect of yieldcomponent factors on wheat yield. The correlation and path analysis of the yield and main traits of 63 wheat varieties promoted by Henan Province from 2005 to 2014 were analyzed. The results showed that, in recent years, the yield of new wheat varieties in Henan Province had an increasing trend, with an average annual growth of 13.0556 kg/hm2. The variation coefficient of the main traits was in an order as: spike per hectare ＞ grains per spike＞ plant height ＞ 1000 grain weight. The correlation degree between the main traits and yield was in an order as: 1000 grain weight ＞ grains per spike ＞ plant height ＞ spike per hectare. The direct path coefficient of the three factors to the yield was positive: 1000 grain weight＞grains per spike＞spike per hectare. According to the results of the analysis, the ecological conditions in Henan Province and the current cultivation habits, wheat breeding and high-yield variety cultivation should be focused on the coordination of spike per hectare and grains per spike, the effective combination of big spike and big group, stable 1000-grain weight, and the coordinated development of the three factors.
