How good is the Zhongdan 859 corn seed? Variety characteristics introduction
Zhongdan 859 is a corn seed bred by Liaoning Dongya Seed Industry Co., Ltd. and the Institute of Crop Sciences, Chinese Academy of Agricultural Sciences. This variety has the characteristics of high yield, good lodging resistance and high quality, and is suitable for planting in Jilin Province, Heilongjiang, northern Shanxi Province, most of Inner Mongolia, and the high-cold and cool regions of Gansu. When planting this variety, attention must be paid to the prevention and control of head smut, northern corn leaf blight, stalk rot and gray leaf spot.
Advantages of Zhongdan 859 corn:
1. Zhongdan 859 is a major variety promoted by Liaoning Dongya Seed Industry Co., Ltd. in Northeast China, Gansu and other places, in early-maturing corn regions above 2300 degrees. It is tolerant to low temperatures, early in maturity, widely adaptable, resistant to pests and diseases, resistant to lodging, stable-yielding, high-yielding, uniform in ear, and good in grain quality. It is a good variety suitable for mechanical harvesting with high economic benefit.
2. Since its launch, Zhongdan 859 has been well received after several years of promotion in the third accumulated temperature zone of Heilongjiang, especially gaining the trust of large numbers of large-scale growers for its lodging resistance, suitability for mechanical harvesting, good grain quality and fast dehydration.
3. Zhongdan 859 seedlings have purple leaf sheaths and green leaves. They are tolerant to low temperatures and poor soil, have strong sprouting vigor and good emergence, and a single sowing ensures full stand. Sow in early May, with a suitable density of 4000—4500 plants per mu.
4. Zhongdan 859 has neat ear placement and uniform ears. The ears are conical at the early stage and gradually expand into cylindrical ears. Grain filling is fast, making it suitable for both mechanical harvesting and ear harvesting.
5. Zhongdan 859 has a thin cob and deep kernels. The kernels are golden yellow, wide and large, dehydrate quickly, and have good grain quality, so they sell at a higher price and bring greater profit.
