“豫禾358”是以“甸M383”为母本、以“F784”为父本杂交选育而成,2014-2015年2年区域试验平均产量12 897.5 kg /hm2,比对照“先玉335”增产6.2％.2015年生产试验平均产量12 544.9 kg /hm2,比对照 “先玉335”增产6.9％,该品种于2016年3月通过吉林省农作物品种审定委员会审定.“豫禾368”是以外引系“M287”为母本、以“F784”为父本杂交选育而成,2014-2015年2年区域试验平均产量13 198.6 kg /hm2,比对照“先玉335”增产5.5％.2016年生产试验平均产量12 693.8 kg /hm2,比对照“先玉335”增产6.6％.该品种于2017年4月通过吉林省农作物品种审定委员会审定.2 个品种主要特点是耐密、高产、广适、优质、高效、抗性好,适合吉林省玉米中晚熟区和中熟区高密种植.“,”A new maize variety“Yuhe 358”is a hybrid selected from the male parent“F784”and the female parent“Dian M383”. Its average yield was 12 897. 5 kg /hm2 in the two-year regional test from 2014 to 2015,6. 2％ higher than that of the control variety “Xianyu 335”. Its yield was 12 544. 9 kg /hm2 in the production test in 2015,6. 9％ higher than that of the control variety “Xianyu 335”.“Yuhe 358”was examined and approved by Jilin Evaluation Committee of Crop Variety in March 2016. A new maize variety“Yuhe 368”is a hybrid selected from the male parent “F784”and the female parent“M287”. Its average yield was 13 198. 6 kg /hm2 in the two-year regional test,5. 5％ higher than that of the control variety“Xianyu 335”. Its yield was 12 693. 8 kg / hm2 in the production test in 2016,6. 6％ higher than that of the control variety“Xianyu 335”. “Yuhe 368”was examined and approved by Jilin Evaluation Committee of Crop Variety in April 2017. The main cultivation characteristics of the two varieties are density resistance,high yield, wide adaptability,high quality,high efficiency and good resistance,and they are suitable for highdensity planting in the middle-late-maturing and middle-maturing regions of Jilin province.
