大豆新品种吉育310的选育

Breeding of A New Soybean Cultivar Jiyu 310

吉育310是吉林省中早熟组大豆新品种,2010年吉林省农业科学院大豆研究所以公交0123-4为母本、(公交0123-4×公交20126-13)F1代为父本杂交组合,采用系谱法经多年鉴定选育而成。籽粒粗蛋白质含量40.89%,粗脂肪含量20.02%。人工接种高抗花叶病毒病1号和3号株系,中抗灰斑病1号和7号混合生理小种。区域试验平均产量3 382.9 kg·hm-2,较对照增产6.7%。生产试验平均产量3 339.5 kg·hm-2,较对照增产5.5%。

A new soybean variety Jiyu 310 was bred from female parent Gongjiao 0123-4 and male parent F1 hybrid developed by crossing Gongjiao 0123-4 with Gongjiao 20126-13 by Soybean Research Institute of Jilin Academy of Agricultural Sciences. Through pedigree method and systematic selection procedure of several years, Jiyu 310 with the character of mid-early maturity in Jilin Province was selected. The contents of crude protein and crude fat in the seed of Jiyu 310 were 40.89% and 20.02%, respectively. Under the natural field condition of artificial inoculation, Jiyu 310 showed the characteristics of high resistance to strains No.1 and No.3 of soybean mosaic virus and medium resistance to mixed physiological races No.1 and No.7 of soybean frogeye leaf spot. In the regional tests, the average yield of Jiyu 310 was 3 382.9 kg·ha-1, and 6.7% higher than that of the control. In the soybean production tests, the average yield of Jiyu 310 was 3 339.5 kg·ha-1, and 5.5% higher than the control.
