高油大豆品种合农66选育与应用

Breeding and Application of High Oil Soybean Variety Henong 66

为选育高油大豆新品种,提升油用大豆生产竞争力,黑龙江省农业科学院佳木斯分院通过优选亲本、种质创新、建立选择群体及改良选择与培育方法,育成了高油大豆新品种合农66,2014年由黑龙江省审定推广,2016年获植物新品种保护权。该品种区域试验产量2863.4 kg·hm^-2,比对照合丰51增产12.0%;生产试验产量2625.7 kg·hm^-2,比对照合丰51增产9.4%;油分含量21.87%,蛋白质含量36.52%;中抗灰斑病兼抗疫霉病;出苗至成熟生育日数113 d,需≥10℃活动积温2250℃,适宜北方春大豆早熟区种植;该品种2013-2018年累计种植面积49.2万hm 2,纯增产大豆11.07万t,创纯社会效益44585.7万元。该品种选育与应用对高油大豆育种具有指导意义。

In order to select new high oil soybean varieties and improve the competitiveness of oil soybean production,Jiamusi Branch of Heilongjiang Academy of Agricultural Sciences,through the optimization of parents,germplasm innovation,establishment of selection groups and improvement of selection and cultivation methods,had bred a new high oil soybean variety,Henong 66,which was approved and promoted by Heilongjiang Province in 2014 and granted the protection right of new plant varieties in 2016.The regional trial yield of the variety was 2863.4 kg·hm^-2,which was 12.0%higher than that of the control Hefeng 51;the production trial yield was 2625.7 kg·hm^-2,which was 9.4%higher than that of the control Hefeng 51;the oil content was 21.87%,the protein content was 36.52%;it was resistant to both gray spot and Phytophthora;the number of days from emergence to maturity was 113 d,which needs to be≥10℃active accumulated temperature of 2250℃,which was suitable for planting in the early maturing area of spring soybean in North China;From 2013 to 2018,the total planting area of this variety was 492000 hm 2,the net yield of soybean was 110700 t,and the net social benefit was 445.857 million yuan.The breeding and application of this variety have guiding significance for high oil soybean breeding.
