宁麦９号的高产及稳产性十分突出，在１９９５～１９９７年江苏省淮南片小麦良种区域试验的２９个点（次）中，绝大多数点（次）的产量居第一位，平均亩产４５０ｋｇ左右，比对照品种扬麦１５８增产达５３８％～１４５４％。该品种的高产优势主要为成穗数多，小穗小花结实率高，每穗实粒数多。一般产量结构为：每亩３４万穗左右，每穗４０粒以上，千粒重３２～３４ｇ。宁麦９号耐湿性和后期耐高温逼熟能力均较强，高抗梭条花叶病，赤霉病和纹枯病较轻。根据该品种在不同产量水平下产量结构变化的特点和各地高产经验，探讨了宁麦９号高产栽培策略、合理的群体结构及适宜的播种期等。
The high yield and stable yield of Ningmai 9 were outstanding. In the 29 points (times) of the regional test of wheat in Huainan, Jiangsu Province from 1995 to 1997, the output of the most point Production about 450kg, compared with the control varieties Yangmai 158 yield up to 5 38% ~ 14 54%. The varieties of high yield advantage mainly for the number of spikes, spikelets fruiting rate, spikelets per particle number. The general yield structure is: about 340000 spikes per acre, more than 40 grains per spike, grain weight 32 ~ 34g. Ningmai 9 had better moisture-tolerance and late-maturing ability of high temperature resistance, high resistance to shuttle mosaic disease, scab and sheath blight. According to the characteristics of the yield structure of the varieties at different yield levels and the experiences of high-yielding in different places, the high-yielding cultivation strategies of Ningmai 9, reasonable population structure and suitable sowing dates were discussed.
