摘要：

为筛选适配功能型食品研发的青稞优质种质，建立多性状协同的评价体系，以甘肃省农业科学院选育的11个春性青稞新品系及对照品种‘陇稞1号’为材料，测定分蘖数、株高、穗长等7项生长指标及粗蛋白、β-葡聚糖、总膳食纤维等6项营养指标，结合灰色关联分析法量化指标间关联度，综合评价品系优劣。结果表明，参试品种产量5323.99~7618.47 kg/hm2，均达到5000 kg/hm2以上，β-葡聚糖含量5.42%~7.04%，全部高于5%，品质均达到国家优级标准；其中品系202004产量最高，且β-葡聚糖(6.78%)和可溶性膳食纤维含量(16.77%)均高于对照品种，功能特性突出。灰色关联分析结果显示，生长指标与营养指标关联值均在0.6以上，呈较强正相关。穗长是粗蛋白（关联度0.7573）、灰分（关联度0.7719）的主导因子。株高是β-葡聚糖（关联度0.8006）的主导因子，叶片宽是水溶性浸出物（关联度0.7745）和总膳食纤维的主导因子，分蘖数是粗脂肪（关联度0.7760）的主导因子。产量关联分析表明，叶片长是产量的核心主导因子（关联度0.8134），粗脂肪为次要因子（关联度0.8074）。本研究明确了功能性青稞关键评价指标及调控点，品系202004可作为保健型青稞开发的优选材料，研究结果可为功能型青稞定向选育与栽培调控提供科学依据。

Abstract:

In order to screen high-quality germplasm of hulless barley suitable for functional food research and development, and establish a multi-trait collaborative evaluation system, 11 new lines of spring hulless barley selected by Gansu Academy of Agricultural Sciences and the control variety ‘Longke 1’ were used as materials in this study. Seven growth indexes such as tiller number, plant height and ear length, and six nutritional indexes such as crude protein, β-glucan and total dietary fiber were measured. The correlation degree between the indexes was quantified by grey correlation analysis method to comprehensively evaluate the strains. The yield of the tested varieties all reached more than 5000 kg/hm2, and the quality reached the national excellent standard, especially the β-glucan content, which was all above 5%. The yield of the strain 202004 is the highest, reaching 7618.47 kg/hm2, and its β-glucan and Insoluble dietary fiber contents are higher than the CK, reaching 6.78% and 16.77% respectively. The gray correlation analysis results showed that the correlation values between the selected growth indicators and nutritional indicators were high, both above 0.6. Among them, ear length is the dominant factor in crude protein and ash content. Plant height is the dominant factor in β-glucan. Blade width is the dominant factor in EXTRACT and total dietary fiber. Tiller number is the dominant factor in crude fat. Leaf length is the dominant factor in yield, and crude fat is a secondary factor. This strain can be considered for development in health care. The early management to promote seedling growth should be the main focus in the cultivation.
