摘　　要：培育筛选耐低温花生对促进花生种植区域向高纬度扩张、提高花生产量非常重要。为了建立花生耐低温鉴选技术,本试验对86份花生资源进行了发芽期室内鉴定(2℃培养4 d,10℃培养5 d)和出苗期田间鉴定。相关性分析表明两种鉴定方法存在极显著相关性,共筛选到18份在发芽期和出苗期均耐低温的花生种质。本研究为花生耐低温品种培育筛选提供了鉴选技术和种质资源。Cultivating and screening low temperature resistant peanut is essential to promote the expansion of peanut planting area to high latitude and improve peanut yield.In this experiment,86 peanut germplasms were identified in germination stage(2℃,4 d and 10℃5 d)and emergence stage.Correlation analysis showed a significant correlation between the two identification methods,and 18 peanut germplasms resistant to low temperature during both germination and emergence stages were screened.This study provides selection techniques and germplasm resources for the breeding of low temperature tolerant peanut varieties.
