高油高产抗病大豆新品种东农69的选育和栽培技术

Breeding and Cultivation Technique of High-Oil, High-Yield and Disease-Resistant Soybean New Variety Dongnong69

摘要: 本文介绍了高油高产抗病大豆品种东农69的选育过程和栽培技术。东农69是由东北农业大学大豆科学研究所于2007年以合丰50为母本、北交922为父本进行有性杂交选育而成，该研究描述了东农69品种的产量表现、品种特征特性以及主要栽培技术。东农69参加2014~2015年黑龙江省大豆品种区域试验，2年平均产量3155.1 kg/hm²，比对照绥农26增产6.9%；2016年参加生产试验，平均产量2431.9 kg/hm²，比对照绥农26增产9.8%。该品种生育期120 d，百粒重19.8 g，籽粒蛋白质含量37.35%，脂肪含量22.59%，适宜在中上等肥力地块种植，最佳种植密度范围为22~25万株/hm²。东农69是高油、高产、抗病大豆新品种，适宜在黑龙江省第二积温带下限种植。

Abstract: It is vital to introduce the breeding and cultivation technique of soybean new variety Dongnong69, which is high-oil, high-yield and disease-resistant. Dongnong69 was developed based on the Hefeng50 as female parents and the Beijiao922 as male parents by Soybean Research Institute and Northeast Agricultural University in 2007. In addition, the yield is one of the essential factors regards to Dongnog69. It participated in the soybean regional tests and productive tests in Hei-longjiang Province during 2014~2015 and 2016. The average yield was 3155.1 kg/hm² and 2431.9 kg/hm². Compared with the control variety Suinong26, it increased 6.9% and 9.8% respectively in the tests. Moreover, the features of Dongnong69 and the main cultivation technique of the variety are important elements that need to be mentioned. The growth period of Dongnong69 was 120 days, the weight of 100-seed was 19.8 g, the protein content of seed was 37.35%, and the fat content was 22.59%. Dongnong69 was easy to obtain a high yield in medium and high fertility fields, whose optimal planting density was 220~250 thousand plants/hm². Hence, Dongnong69 was a new variety with high oil, high yield and disease resistance, which can be cultivated in Accumulated temperature zone II, Heilongjiang Province.
