Abstract: In order to further explore the feed value of Nendan 29 and relieve the demand for feed corn, the common corn variety Nendan 29 was planted and harvested as silage varieties, and planted in plot trials and silage production in different regions.The results showed that it had the characteristics of high resistance to lodging, resistance to large leaf spot, head smut, stem rot, and strong green retention.The biological yield was high, and the average biological yield of the production field exceeded 3.5 t·（667 m~2）^-1.The commercial quality crude protein belonged to the first grade, the acid detergent fiber belonged to the second grade, and the neutral detergent fiber belonged to the first grade, dry matter at harvest was 31.4%,starch was 37.0%,reaching the target of “Double 30” breeding.Nendan 29 can be planted as a silage variety instead of conventional silage varieties, and its excellent resistance and commercial quality were conducive to reducing the risk of forage silage planting.
