摘要
以黄淮海和南方地区176份大豆品种为材料,利用改进的大批量小样品豆腐与豆乳得率实验室定量分析技术,分析干豆腐、湿豆腐和干豆乳得率的变异特点。结果表明：（1）关内黄淮海和南方地区100g大豆干基可得干豆腐、湿豆腐、干豆乳分别约45.60~73.53g、368.74~622.14g和58.05~83.33g,最高值高于平均31.14%、17.33%和17.71%,总体上变异是丰富的。黄淮海和南方地区品种得率低端接近,高得率品种南方多于黄淮海地区;育成品种高得率材料在夏播类型中较多;1995年后育成品种高得率数与1995年前数十年的相仿。（2）遴选出29份高得率品种,南方和黄淮海地区分别有17和12份可供生产应用或作为育种特异种质利用,其中南农菜豆5号、南农菜豆1号和湘春豆16等3份＂三高＂种质均来自南方地区。
In breeding for tofu and soymilk output, one of the basics is to reveal the genetic variability in genetic resources and breeding materials. The present study aimed at characterization of variation of tofu and soymilk output in soybean cultivars from Huang-Huai-Hai area and southern China, another goal of this study is to screen and select elite sources for breeding programs. A sample consisted of 176 cultivars and breeding lines was used to study the genotypic variation of dried tofu output, wet tofu and dried soymilk by using the improved mini-specimen measurement technology for large samples in laboratory. There were large variation among the tested materials in dried tofu output, wet tofu and soymilk, with their ranges of 45.60~73.53 g, 368.74~622.14 g and 58.05~83.33 g respectively and their greatest values were 31.14%, 17.33% and 17.71% higher than their mean values respectively. Cultivars from Huang-Huai-Hai area and those from southern China both showed a similar low output while the number with high output was greater in southern China than in Huang-Huai-Hai area. Cultivars with high output of tofu and soymilk were mainly the summer planting season type. The number of high output cultivars released after 1995 were about the same as that released during a long period before 1995. Total 29 cultivars with high output of tofu and soymilk were screened, among them, 17 from southern China, 12 from Huang-Huai-Hai area. The three best cultivars, Nannongcaidou No.5, Nannongcaidou No.1 and Xiangchundou 16 with high output of dried tofu, wet tofu and dried soymilk were all from southern China. These elite cultivars can be used in both commercial production and breeding programs in the improvement of these three output traits.
