本文探讨了以穗型和籽粒外观特征为指标早代选择啤酒大麦麦芽品质的可能性。供试材料系优质品系新田二棱1号为亲本的3个组合的 F_3、F_4和 F_5代。采用着粒密度为穗形指标,以籽粒表面皱褶多少为籽粒外观指标。籽粒表面皱褶由评定小组观察判定。各评委间所评定的品种位次在早代相关性较低,但在中期世代相关性较高(r=0.6以上)。着粒密度、籽粒表面皱褶与麦芽品质之间的相关分析表明,籽粒表面皱褶与麦芽汁浸出率、麦芽浸出汁产量及评分的相关性较高,尤其与麦芽汁浸出率相关性更高。不过,未发现与着粒密度有明显关系的性状。各性状世代间相关分析表明,着粒密度、籽粒表面皱褶、麦芽汁浸出率及评分的相关性都比较高。由以上结果可确定,麦芽品质中最重要的麦芽汁浸出特性可根据籽粒表面皱褶进行选择。此法从处理大量材料的早期至中期世代都是有效的。
In this paper, the possibility of choosing the malting quality of beer barley from early generation with the characteristics of panicle appearance and grain appearance as an indicator was explored. The tested materials were F_3, F_4 and F_5 generations of three combinations of high quality strain Xintian Erlin No.1. Using grain density as a spike index, the number of grain surface folds as the grain appearance index. The grain surface folds were observed and judged by the assessment team. The rankings among the judges were lower in early generation, but higher in middle generation (r = 0.6). Correlation analysis between grain density, grain surface folds and malt quality showed that grain surface folds had a higher correlation with wort leaching rate and malt extract yield and score, especially with the wort leaching rate . However, no significant association with grain density was found. Correlation analysis between generations showed that there was a high correlation between grain densification, grain surface folds, wort leaching rate and scoring. From the above results, it is confirmed that the most important wort leaching characteristics of the malt quality can be selected according to the grain surface wrinkles. This method is effective from the early to mid-generation of handling large quantities of material.
