Wheat

　　Nanyang is a major wheat-producing area in Henan Province, with an annual planting area of around 8.9 million mu, accounting for 2.5% of the province's total wheat acreage. The city’s total wheat output is approximately 2.5 billion kilograms, making up 125% of the province’s total wheat production. Among them, Wancheng District and Xinye County are the city’s high-yield wheat counties (districts), with an average yield of around 350 kilograms per mu. In 1998, the average yield in both counties exceeded 400 kilograms per mu, with Wancheng District achieving an average yield of 428.6 kilograms per mu on 554,000 mu of wheat. The utilization of wheat varieties in Nanyang has undergone six rounds of updates, forming a dynamic balance system primarily based on Yumai 35 and Yumai 18, supplemented by new varieties such as Bainong 64, Zhoumai 11, and Zhenghan 1. In the semi-humid wheat-growing areas of basin plains and hills with high fertility and non-stubble fields, Bainong 64 is mainly planted. Medium-season crops feature Yumai 35 and Yumai 18, while late-season crops are dominated by Wan 798. In medium-to-low-yield wheat fields on hills and mounds, Zhenghan 1 is primarily planted in early-season fields, supplemented by Mianong 4 in medium-season fields. For wheat-cotton intercropping fields, Yumai 18 and Yumai 35 are mainly used. In double-cropping rice-wheat fields, Yangmai 158 and Wan 798 are the primary varieties, supplemented by Mianong 2. In the cool, high-fertility wheat fields of the northeastern wind gap area of Nanyang, Bainong 64 is mainly planted in early-season fields, Zhoumai 11 in medium-season fields, and Yumai 18 and Wan 798 in late-season fields. Yumai 35 and Wan 798 are two high-quality bread-making wheat varieties cultivated in Nanyang. They demonstrate consistently high yields, generally exceeding 400 kilograms per mu, and are suitable for cultivation across the province and in the middle and lower reaches of the Yangtze River.
