Abstract
Drought occurring at all growth phases of peanut (Arachis hypogaea L.) reduced pod yield and affected the physiological traits. All peanut accessions increased the percentage of root length density (%RLD) in response to terminal drought, but pod yield was greatly reduced. The increases in RLD varied among peanut genotypes. ICGV 98348 and Tifton 8 were the most resistant accessions based on RLD and pod yield. Pod yield was positively correlated with RLD and relative water content. The results would provide a better understanding on the responses of peanut to terminal drought to improve selection efficiency of peanut breeding for drought resistance.
