晋麦78号系山西省农业科学院小麦研究所旱地育种研究室以扬麦5号为母本、晋麦50号为父本通过有性杂交选育而成。该品种冬性,中早熟,平均生育期236d。幼苗叶色淡绿,抗寒耐冻,分蘖力强,株型较松散;株高75～80cm,穗长方形,穗粒数28～35粒,千粒重37～41g;具有抗千热风耐高温、耐旱、落黄好等特点。在山西省南部旱地区试中平均单产达3666.6kg/hm~2,较对照晋麦47号平均增产6.52%,在生产试验中平均产量达4165.5kg/hm~2,较对照平均增产7.0%;适宜晋南麦区旱地推广种植。
Jinmai 78 is a drought-resistant breeding research center of Wheat Research Institute of Wheat Research Institute of Shanxi Academy of Agricultural Sciences bred by sexual crosses with Yangmai 5 as female parent and Jinmai 50 as male parent. The varieties of winter, early maturity, the average growth period of 236d. Seedling leaves light green, cold and freezing resistance, strong tillering ability, more loose plant type; plant height 75 ~ 80cm, spike rectangle, grain number 28 ~ 35, grain weight 37 ~ 41g; Dry, falling yellow and so on. The average yield per unit area reached 3666.6kg / hm ~ 2 in the trial of arid area in Shanxi Province, which was 6.52% higher than that of Jinmai 47. The average yield in the production experiment was 4165.5kg / hm ~ 2, which increased by 7.0% on average. Suitable for dry planting in Jinnan wheat area.
