| 摘 要： | 通过对大豆优良品种黑河14的选育,作者认为:在大豆超早熟育种的亲本选配上,应选择双亲生育日数差值小、花期短、鼓粒快、株体繁茂、中日性、耐低温的极早熟种质资源作为杂交亲本.以极早熟、丰产、抗病品种间杂交为最佳组合,通过有性杂交获得早熟性基因累加超亲遗传后代,进而创造出更早熟的杂交后代材料,于F2和F3世代,以早熟、抗病性为主进行选择,严格淘汰晚熟、感病单株.F4世代以丰产性状选择为主,从早熟、抗病后代的优良株系中大量选拔丰产性状优异的单株,混合成品系,下年进行品系鉴定.由于大豆生态适应区域明显,为此,充分结合当地生态条件进行选育更易获得成功.

| Abstract: | The author thinks that super early-maturity seed resource should be chosen as hybrid parents on the parents choice of super early-maturity soybeans breeding because the difference of parents' breeding days is little,the florescence is short,the speed of soybean grain swelling is fast,the soybean plant is exuberant,the response to daytime length is neither long nor short and it is cold tolerance.The varieties with super early-maturity,high yield and diseasesresistence were crossed,and get early-maturity gene and super heredity generation by sexual hybrid,then created more early maturity hybrid progeny. In F_2 and F_3,we mainly made choice of early-maturity and diseases resistence.In F_4,we mainly chose high yield,and selected single plant from early-maturity and diseases resistence generation,mixed into strain and identified it in the next year.Because of sensitive response to ecological environment,soybeans breeding will be easy to succeed according to local. |
