摘　　要：为了明确芽用大豆育种目标,为选育豆芽专用品种提供参考,本研究以初筛的12个芽用大豆品种(品系)为试验材料,模拟工厂化大豆芽产品的培育工艺与条件,采用人工气候箱培养技术,对各供试大豆材料的种子特性和芽用特性指标进行了系统比较和分析。结果表明:粒重、豆芽下胚轴长度和粗度只受大豆自身基因型的影响,与环境、基因型环境互作无关;不同质量级别的豆芽比例,可以作为芽用大豆选育的筛选指标;子叶破裂、较差豆芽比例高是豆芽质量降低的主因。相关分析结果表明:粒重与优异及良好豆芽鲜重、下胚轴粗度呈极显著正相关;优异豆芽比例与豆芽产出率呈极显著正相关;下胚轴长度与优异豆芽比例呈极显著正相关,下胚轴粗度与优异豆芽鲜重呈极显著正相关。本研究能够为芽用大豆品种的选育提供一个切实可行的育种后代筛选标准。In order to identify the goals and provide references for the breeding selection of sprout varieties, twelve soybean genotypes selected by previous study were used for experimental materials. Under the processing conditions and technologies similar to industrial production, the characteristics of seed size and soybean sprouts were analyzed and compared systematically in the artificial climate incubator. The results showed that there were distinct differences in the 100-seed weight, hypocotyl length and diameter among various genotypes, but no relevance to the environmental factor and genotype-environment interaction effect. The percentages of soybean sprout with different quality levels can be used as selection criterion in soybean breeding for sprout. Damaged or cracked cotyledons and high percentage of low-quality sprouts were the primary cause of sprout quality reduction. The results of correlation analysis indicated that there were highly significant correlations among 100-seed weight, fresh weight of high-quality and average-quality sprouts, and hypocotyl diameter. There was a positive correlation between percentage of highquality sprouts and sprout yield. A very significant positive correlation existed between hypocotyl length and percentage of high-quality sprouts. The hypocotyl diameter had significant positive correlation with fresh weight of high-quality sprouts. This study can provide practical criteria for selecting progenies in breeding soybean varieties used for sprout production.
