摘要
合农74是黑龙江省农业科学院佳木斯分院结合分子设计育种技术,针对高油高产优良性状育成的大豆新品种。通过黑龙江省品种比较试验、区域试验和生产试验。三年平均蛋白质含量37.59%,平均脂肪含量22.23%,为高油品种。植株具备高大繁茂,分枝性好的特性。该品种籽粒圆形,种皮黄色、有光泽,种脐黄色,百粒重为19.6 g左右。经过三年的抗病接种试验,鉴定为中抗灰斑病。适应区生育日数为120 d左右,活动积温2 450℃左右。该品种通过生物技术与常规育种的紧密结合而育成,拓展了大豆育种途径,突破了资源环境约束,提高了育种效率,对作物分子育种创新起到推动作用。
The new soybean variety Henong 74 was bred by Jiamusi Branch Academy of Heilongjiang Academy of Agricultural Sciences through molecular design breeding aiming at high oil, high yield and fine characters. Through the varieties comparison test, varieties regional test and varieties production test in Heilongjiang, the analysis of three-year average quality showed that the protein content was 37.59% and average fat content was 22.23%, suggesting high-oil varieties. The plant was tall and luxuriant with good branching. The seed of this variety were round, the seed coat was yellow and glossy, and the hilum was yellow, with the 100-seed weight of around 19.6 g. After inoculation test for three years, the results demonstrated moderate resistance to gray leaf spot. The growing days in the adaptive area was around 120 d, and the active accumulated temperature needed to be at around 2 450 ℃. This variety was bred through the combination of biotechnology and conventional breeding, which expanded the approaches of soybean breeding, broke through the restriction of resources and environment, and improved breeding efficiency, so it could promote the innovation of crop molecular breeding.
