【摘要】 宏瑞66(原代号X9687)是山西省农业科学院玉米研究所以自选系A858为母本、自选系P336为父本,经过基因重组、性状互补,选育而成的中熟玉米单交种。经过多年试验示范,该品种增产潜力大,适应性广,生物产量高,活秆成熟;具有抗病抗倒、抗旱及品质好等特点,在山西忻州春播生育期为128 d,需≥10℃有效积温2 700℃·d;种植密度为6.00万～6.75万株/hm2。2018年5月通过山西省农作物品种审定委员会审定,审定编号为:晋审玉20180055。更多还原

【Abstract】 Hongrui 66(original code X9687)is a single plant type of medium mature maize with compact plant type,which was bred by Institute of Maize,Shanxi Academy of Agricultural Sciences,through gene recombination and complementary traits,the self selection line A858 is the mother parent and the self selection line P336 is a male parent.After years of experiment and demonstration,the variety has high yield potential,wide adaptability,high biological yield and mature stem.It has the characteristics of resistance to disease,lodging resistance,drought resistance and good quality.The growth period of spring sowing in Xinzhou,Shanxi is 128 d,with an effective accumulated temperature of 2 700 ℃·d(≥10 ℃).The planting density is 60 000-67 500 plants/hm2.It was approved by the Shanxi Provincial Crop Variety Approval Committee in May 2018,and the number was Jinshenyu 20180055.更多还原
