Abstract：Huaimai 1033 a new wheat variety bred by Jiangsu Xuhuai Area Huaiyin Institute of Agricultural Sciences.In this study,the high yield,stable yield,adaptability and yield composition of Huaimai 1033 were analyzed by the regional test data of Shuidi group in south Huanghuai of national winter wheat cultivar experiment from 2017 to 2019.The results showed that the average panicle number of Huaimai 1033 was 6.058 8 million/hm2,the number of grains per spike was 33.43,the 1 000-grain weight was 42.83 g,the seed setting rate was 71.43％,and high stability coefficient was 85.7％.During 2017-2018,Huaimai 1033 ranked second in yield and third in stability,and had good performance in 16 pilot projects.The yield of Huaimai 1033 was positively correlated with the whole growth period,plant height,effective spike number and number of grains per spike,and effective spike number of Huaimai 1033 had the greatest direct effect on yield.Therefore,in the production of Huaimai 1033,the effective spike number should be ensured under the cooperation of good cultivation technology.The advantage of multiple spikes should be fully utilized.The number of grains per panicle and thousand grain weight should be appropriately increased.The three factors of yield composition should be taken into account.
