摘 要: | 目的]为探索大麦主要农艺性状的遗传规律,为我省品种审定和推广提供科学依据。方法]以14个大麦品种为材料,进行主要农艺性状与产量的统计分析。结论]14 个大麦品种农艺性状存在丰富的遗传变异,7个农艺性状变异程度与范围较大,有一定的优势可利用。相关分析表明,大麦各农艺性状间存在复杂的相关性,且多个性状影响产量,穗粒数与籽粒产量呈显著正相关。供试材料可聚为两大类:中矮秆型和中高秆型。

Abstract: | Objective] To explore the genetic laws of the main agronomic traits of barley and provide scientific basis for variety approval and promotion in our province. Method] 14 barley varieties were selected as materials for statistical analysis of the main agronomic traits and yield. Conclusion] There is abundant genetic variation in the agronomic traits of the 14 barley varieties, and 7 agronomic traits show significant variation in degree and range, indicating certain advantages that can be utilized. Correlation analysis shows a complex relationship among various agronomic traits of barley, and multiple traits have an impact on yield, with spikelet number showing a significant positive correlation with grain yield. The tested materials can be classified into two categories: medium-short straw type and medium-high straw type. |
