大豆品种齐农5号是黑龙江省农业科学院齐齐哈尔分院于2007年以合丰25为母本,丰豆3号为父本,进行有性杂交选育而成的抗病、高油新品种。该品种具有抗胞囊线虫病,高油,稳产丰产性好等特点。2年区域试验,10点次全部增产,平均产量2615.2 kg·hm^-2,较对照品种嫩丰18增产11.2%;1年生产试验,7点次全部增产,平均产量2611.1 kg·hm^-2,较对照品种嫩丰18增产10.9%。蛋白含量为39.05%,脂肪含量为21.91%,抗SCN3。出苗至成熟生育日数123 d左右,需≥10℃活动积温2550℃左右,适宜黑龙江省第一、二积温带种植。2018年通过黑龙江省农作物品种审定委员会审定(黑审豆2018006)推广种植,现成为抗线虫区对照品种。

Qinong No.5,a new soybean variety with disease resistance and high oil content,was bred in 2007 with Hefeng 25 as female parent and Fengdou No.3 as male parent in Qiqihar Branch of Heilongjiang Academy of Agricultural Sciences.The variety has the characteristics of resistance to cyst nematode,high oil,stable and high yield.In the two-year regional test,all production was increased at 10 points.The average yield of 10 points was 2615.2 kg·hm^-2,11.2%higher than that of the control variety Nenfeng 18.In the one-year production test,the average yield of 7 points was 2611.1 kg·hm^-2,10.9%higher than that of the control variety Nenfeng 18.The protein content was 39.05%,fat content was 21.91%and SCN3 resistance.The number of days from emergence to maturity was about 123,and the active accumulated temperature of greater than or equal to 10℃is about 2550℃,which was suitable for planting in the first and second accumulated temperate zone of Heilongjiang Province.In 2018,Qinong No.5 was approved and popularized by Heilongjiang Provincial Crop Variety Approval Committee,and now it has become a control variety in nematode resistant area.
