【摘要】 沧农99是由沧州市农林科学院选育的玉米新品种。本研究利用最小显著差数法(LSD)、Shukla变异系数、增产点率对河北省众城玉米科企联合体试验中沧农99的丰产性、稳产性、广适性进行分析评价。结果表明：在河北多地，沧农99较对照品种郑单958增产极显著，具有良好的丰产性；其Shukla变异系数小，具有良好的稳产性；增产点率高，具有良好的广适性。沧农99适宜在河北省沧州、石家庄、唐山、衡水、保定等地夏播玉米区大面积推广种植。更多还原

【Abstract】 Cangnong 99 is a new maize variety bred by Cangzhou Academy of Agriculture and Forestry.In this study, LSD method, Shukla coefficient of variation and yield-increasing point rate were used to analyze and evaluate the adaptability of high and stable yield of Cangnong 99 in the test of the Zhongcheng Corn Science and Technology Enterprise Joint Body in Hebei Province.The results showed that Cangnong 99 was significantly higher in yield than the control variety Zhengdan 958 in Hebei Province, and it had good high yield, small variation coefficent of shukla and good stability, high yield-increasing point rate and good adaptability.It is suitable for large-scale popularization and planting in summer sowing corn areas in Cangzhou, Shijiazhuang, Tangshan, Hengshui and Baoding, Hebei Province.更多还原
