国审高油大豆新品种星农12的选育改良

Breeding and Improvement of New National Certificated High-Oil Soybean Variety Xingnong 12

为选育适合黑龙江省第二积温带南部区域种植的高产优质抗病大豆新品种,本文系统阐述了星农12的选育过程、特征特性、产量表现和栽培技术。星农12是哈尔滨明星农业科技开发有限公司于2010年以明星-5为母本、龙菽1号为父本杂交育成的大豆新品种,育种者在注重产量提升的同时兼顾了品质性状的改良。2018-2019年,星农12参加北方春大豆中早熟组区域试验,两年平均产量3115.50 kg·hm^(-2),比对照品种合交02-69增产6.05%。2019年参加北方春大豆中早熟组生产试验,生产试验平均产量为3130.50 kg·hm^(-2),比对照品种合交02-69增产9.50%。2020年通过黑龙江省大豆专业审定委员会品种审定(审定编号:黑审豆20200007),2021年通过国家农作物品种审定委员会审定(审定编号:国审豆20210012)。该品种表现出适应区域广,高产、高油、抗倒、易机收、籽粒商品性好等特点,适宜在黑龙江省第二积温带大豆产区推广。

In order to select high-yield,high-quality,and disease resistant soybean varieties suitable for planting in the southern region of the second accumulated temperature zone in Heilongjiang Province,this article systematically elaborated on the breeding process,characteristics,yield performance,and cultivation techniques of Xingnong 12.Xingnong 12 was a new soybean variety developed by Harbin Mingxing Agricultural Technology Development Co.,Ltd.in 2010 through crossbreeding Mingxing-5 as the female parent and Longshu 1 as the male parent.The breeders focus on increasing yield while also improving quality traits.From 2018 to 2019,Xingnong 12 participated in the regional trial of the early maturing group of northern spring soybeans,with an average yield of 3115.50 kg·ha^(-1) over two years,an increase of 6.05%compared to the control variety Hejiao 02-69.In 2019,participated in the early maturing group production trial of northern spring soybeans,with an average yield of 3130.50 kg·ha^(-1),an increase of 9.50%compared to the control variety Hejiao 02-69.In 2020,it passed the variety approval of Heilongjiang Province Soybean Professional Approval Committee(approval number:Heishendou 20200007),and in 2021,it passed the approval of National Crop Variety Approval Committee(approval number:Guoshendou 20210012).This variety exhibits characteristics such as wide adaptability,high yield,high oil content,lodging resistance,easy mechanical harvesting,and good grain marketability,making it suitable for promotion in the soybean production area of the second accumulated temperature zone in Heilongjiang Province.
