| 摘 要： | 目的]明确黑龙江省春大豆苗期抗旱类型，筛选抗旱资源，为黑龙江省选育抗旱春大豆品种提供优异亲本。方法]利用干旱反复法对黑龙江省78份春大豆材料进行干旱胁迫，采用盆栽试验，每盆（50em×30cm）保苗10株，每处理3次重复，对照土壤含水量为80％，在大豆3初复叶时进行胁迫，通过调查幼苗的存活率确定不同材料的抗旱类型。结果]78份供试材料中，抗线号、龙字号、大豆品种和黑河号品种抗旱和不抗旱类型分布比例相差不大，而黑农号大豆品种全部属于抗旱型材料，合丰号和绥农号大豆品种抗旱类型居多，垦丰号和垦豆号品种全部属于非抗旱类型。结论]耐旱品种有抗线5号、黑农51、黑农52、黑农60、黑农61、龙小粒豆2号、龙青大豆1号、龙黑大豆1号、合丰48、合丰50、合丰51、合农62、绥农28、绥农30、垦丰7；较耐旱品种有抗线4、抗线6、抗线7、黑河43、黑河50、黑河51、黑河53、黑农38、黑农44、黑农48、黑农62、黑农64、黑农65、龙小粒豆1号、合丰35、合丰56、新合丰25、绥农15、垦丰11。

| Abstract: | Objective ] To obtain seedling drought resistance types of spring soybean in Heilongjiang Province and screen out drought resistance resources, which will provide excellent parent for breeding drought-resistance varieties in Heilongjiang Province. Method] Drought stress was conducted on 78 material of spring soybean in Heilongjiang Province by using repeated drought method. Using pot trial, keep a full stand of seed-lings per pot and every treatment with 3 replications. Control soil water content was 80%. Start stress at the beginning of trifoliate compound leaves and determine the drought resistance of different materials by investigating the seedling survival rate. Result ] In 78 germplasms, nema-tode resistance series, long series soybean varieties and Heihe varieties types of drought resistance and drought resistance distribution ratio were similar. And Heihe soybean all belong to the drought type materials. Hefeng series and Suinong series were in the majority drought resisting type. Kenfeng series and Kendou series were all belong to no-drought resisting type. Conclusion] Drought-tolerant species include Kangxian No. 5, Heinong 51, Heinong 52, Heinong 60, Heinong 61, Longxiaolidou No. 2, Longqingdadou No. 1, Longheidadou No. 1, Hefeng 48, Hefeng 50, Hefeng 51, Henong 62, Suinong 28, Suinong 30, Kenfeng 7. Relatively drought-tolerant species include Kangxian d, Kangxian 6, Kangxian 7, Heihe 43, Heihe 51, Heihe 53, Heinong 44, Heinong 48, Heinong 62, Heinong 64, Heinong 65, Longxiaolidou No. 1, Hefeng 35, Hefeng 56, Xinhefeng 25, Suinong 15, Kenfeng 11. |
