[目的]为大豆新品种嘉豆1号的推广及在今后大豆育种中的应用提供理论依据。[方法]介绍嘉豆1号的选育经过、特征特性、适应性及栽培技术,探讨其增产潜力。[结果]嘉豆1号是以东农42为母本,以益嘉97-172为父本有性杂交育成的大豆新品种。该品种区域试验平均产量2 623.9 kg/hm2,较对照品种绥农28平均增产8.8%,生产试验平均产量2 567.0 kg/hm2,较对照品种绥农28平均增产8.3%;蛋白质含量43.22%,脂肪含量19.88%,蛋白和脂肪含量之和63.10%。[结论]嘉豆1号是一个适应性广,蛋白、脂肪含量均较高的大豆新品种,生育日数118 d,需活动积温2 400℃。2012年由黑龙江省品种审定委员会审定推广。 [Objective] The research aimed to provide a theoretical basis for the popularization of new soybean variety “Jia Dou 1” and its application in future soybean breeding. [Method] The breeding, characteristics, adaptability and cultivation techniques of Jiadou 1 were introduced to explore the potential of increasing yield. [Result] Gadou 1 was a new soybean cultivated with Dongnong 42 as female parent and Yijia 97-172 as male parent. The average yield of this variety was 2623.9 kg / hm2, which was 8.8% higher than the control cultivar Suinong28 and the average yield of the trial was 2 567.0 kg / hm2, 8.3% higher than the control cultivar Suinong28. The protein content was 43.22% The content of 19.88%, protein and fat content of 63.10%. [Conclusion] Jiadou No.1 was a new soybean variety with wide adaptability, high protein and fat content, the number of days of birth was 118 days and the active accumulated temperature was 2400 ℃. 2012 by the Heilongjiang Province Examination Committee approved the promotion.
