Abstract: 【Objective】 According to the ripening period of common maize and the quality demand of maize starch deep processing market,the breeding of new varieties with high starch type was carried out in order to alleviate the problems of mixed varieties and uneven quality in Inner Mongolia maize market.【Methods】 Maize hybrid breeding technique,multi-point identification and traditional maize cultivation techniques were combined.【Results】 The Neidan 35 was bredtest was conducted by crossing wih M10ND101 as the female parent and MXZJ853 as the male parent,and the hybrid intra-variety 35 was selected.In 2015,Neidan 35 was repeated seven times at six appraisal sites in Hohhot,Chifeng,Tongliao,Baotou,Bayannur and Ordos,with an average yield of 12 910.5 kg/hm²,an increase of 7.61% over the control Jinshan 33,a significant increase in yield,and samea grain moisture content.That was basically the same as that of the control variety.In the Montco jade consortium trial in 2016—2017,in which the average yield of the production trial was 11 356.5 kg/hm²,an increase of 6.25% over the control;the reproductive period was 128.4 d.As determined by the Ministry of Agriculture and Rural Affairs Grain Quality Supervision and Inspection and Testing Center,the starch content of the maize variety 76.86%,as a high-starch maize varieties;diseases resistance identification results were the following：for the sense of large spot disease（7S）,resistance to leaf spot curvature（5MR）,resistance to silk black ear disease（7.1% MR）,resistance to stem rot（14.7% MR）,resistance to maize borer（3.9R）.In the planting process,pay attention to the amount of water and fertilizer to prevent large spot disease.【Conclusion】 The new maize variety Naidan 35 is high-starch varieties, under ripe conditions,the starch content of the maize variety was 76.86%,it was approved by the Inner Mongolia Variety Approval Committee in 2018, and suitable in the areas with above 2 650 ℃（an≥10 ℃ active cumulative temperature）in Inner Mongolia.
