不同黑花生品种的抗旱性鉴定评价

Identification and Evaluation of Drought Resistance of Different Black Peanut Varieties

通过盆栽试验分析山西南部10个黑花生品种(系)5个性状指标的相关、聚类分析及敏感、抗旱指数,评价不同黑花生品种的抗旱性强弱。结果表明,水地组中,单株果数和结果率、单株生产力和饱果率、单株生产力和理论产量、饱果率和理论产量之间存在显著差异;而旱地组中,仅单株生产力和结果率性状间存在显著差异。按抗旱指数值和多性状聚类结果可将10个品种分为4类,抗旱指数较高的品种有黑美人、临黑3号和新乡农家黑。研究结果可为旱作区黑花生品种推广种植提供理论参考。

To evaluate different black peanut varieties'drought resistance,the paper surveyed five traits of ten varieties under pot experiment through correlation,clustering analysis and sensitivity,drought resistant index.The results showed that the significant difference existed in pods number per plant and fruit ratio,productivity per plant and full-pod ratio,productivity per plant and theoretical yield,full-pod ratio and theoretical yield under water-irrigated groups.There was significant difference in productivity per plant and fruit ratio under dry land groups.Ten varieties could be divided into four kinds according to drought resistant index and clustering analysis results,Heimeiren,Linhei 3 and Xinxiangnongjiahei showed higher drought resistant index.The research results can provide a theoretical reference to black peanut varieties popularization and cultivation in dry farming region.
