摘要
利用隶属函数对山东产地的4个花生品种进行抗旱性综合评价,同时分析4个品种AhNCED1基因的表达情况,研究AhNCED1基因与不同花生品种抗旱性的相关性。结果表明,花生品种间的抗旱性有显著差异,抗旱性强弱为:‘鲁花14号’>‘花育33号’>‘海花1号’>‘花育24号’。干旱胁迫下,叶片AhNCED1的表达量与其抗旱性呈正相关,AhNCED1基因可以作为筛选抗旱花生品种的分子指标。
Four peanut varieties growing in Shandong were screened for drought resistance using the subordi- nate function value. Meanwhile we analyzed the expression level of AhNCED1 gene and studied the relation- ship between the AhNCED1 expression and the drought resistance. The results showed that drought resistance between different varieties differed remarkably, ＇Luhua 14＇〉＇Huayu 33＇〉＇Haihua 1 ＇〉＇Huayu 24＇. Under drought stress, the expression level of AhNCED1 genes positively correlated with drought resistance, which showed that the AhNCED1 gene could as a molecular marker to screen the highly tolerant peanut cultivar.
