Abstract

 

Data of 12 peanut varieties were analyzed with a view to investigate the relationship between root traits and aboveground traits. Results showed that root biomass was positively correlated with aboveground biomass and total biomass at three stages of growth and development. Root activity at different growth stages were significantly and positively correlated with yield at the mature stage. However, a significant negative correlation was observed between yield and root/shoot ratio at the mature stage. It was concluded that the root system possessed a close relationship with aboveground parts, and keeping the root activity of peanut at the mature stage was essential for achieving high and stable yield.

 

Key words: Peanut, root traits, aboveground traits, correlation.
