摘要
利用1个小麦重组自交系群体,对小麦籽粒性状与种子活力的相关关系进行了探索研究。结果表明:小麦种子活力与多数籽粒性状呈正相关,仅与籽粒硬度呈负相关;进一步通过通径分析得知,粒宽、籽粒硬度、千粒重、容重对种子活力影响较大。系统分析后显示:依照低硬度→宽粒、高粒重→容重的顺序可选择出具有较高种子活力的小麦品系,可为育种选择提供参考。
In this study, a recombinant inbred line （RIL） population of wheat was used to study the correlation between wheat grain traits and seed vigor. The results presented that wheat seed vigor was positively correlated with most grain traits, while it was negatively correlated with grain hardness. Path analysis showed that the grain width, grain hardness, thousand - grain weight and grain volume weight had a significant impact on seed vigor. The further analysis indicated that high - seed - vigor wheat lines could be screened out according to the selection order of low grain hardness, wide grain plus great thousand - grain weight, and great grain volume weight, which can provide reference for wheat breeding.
