Abstract

The F1 generation of 21 cross combinations of groundnut was studied. Pod number was positively associated with pod yield while plant height was negatively correlated with yield. Pod number and plant height were also negatively correlated. Pod number and 100 pod weight had higher positive direct effect on yield. Plant height had negative indirect influence through pod number. Therefore selection for pod number and weight will be helpful for yield improvement in groundnut.

Keywords: Groundnut, Correlation, Path analysis
