摘要:
为推广强优势大豆杂交新品种吉育668，介绍了其亲本来源、选育过程、特征特性、产量表现、栽培技术和制种技术要点等内容。吉育 668 是由吉林省农业科学院大豆研究所自2015年开始，以大豆细胞质雄性不育系JLCMS247A为母本，以恢复系JLR227为父本配置杂交组合，经过多年的筛选和产量鉴定独立选育而成的杂交大豆新品种。该品种在2020－2021年参加吉林省区域试验，平均产量2 931.25 kg·hm-2，比对照品种合交02-69增产11.8%，试验点中最高产量为3 783.3 kg·hm-2。2021年参加生产试验，平均产量为2 649.4 kg·hm-2，比对照品种合交02-69增产12.7%，其中最高产量为3 041.0 kg·hm-2。吉育668于2022年通过吉林省农作物品种审定委员会审定，审定编号为吉审豆20220003。该品种籽粒粗蛋白质含量35.39%，粗脂肪含量22.94%，蛋脂合计58.33%，具有突出的高产、稳产特性，属于高油大豆品种，适宜在吉林省延边州和白山市大部分地区、吉林市部分地区等北方春大豆早熟品种生产区域种植。
Abstract:
To promote the new strong-hybrid soybean variety Jiyu 668, this article introduced the parental sources and breeding process, characteristics, yield performance, cultivation techniques, and key points of seed production technology. Jiyu 668 was a new hybrid soybean variety independently selected by the Soybean Research Institute of Jilin Academy of Agricultural Sciences since 2015, using the soybean cytoplasmic male sterile line JLCMS247A as the female parent and the restorer line JLR227 as the male parent to form a hybrid combination. After years of screening and yield identification, it has been developed.This variety participated in regional trials in Jilin Province from 2020 to 2021, with an average yield of 2 931.25 kg·ha-1, an increase of 11.8% compared to the control Hejiao 02-69, and a maximum yield of 3 783.3 kg·ha-1 belon the experimental sites. In 2021, we participated in production trials with an average yield of 2 649.4 kg·ha-1, which increased by 12.7% compared to the control variety Hejiao 02-69.The highest yield per hectare reached 3 041.0 kg·ha-1. Approved by the Jilin Provincial Crop Variety Approval Committee in 2022, with approval number Jishendou 20220003. This variety has a crude protein content of 35.39%, a crude fat content of 22.94%, and a total egg fat content of 58.33%. It has outstanding high and stable yield characteristics and belongs to the high oil soybean variety. It is suitable for planting in a large area and has broad prospects for promotion and application.
