✦ Synopsis

Correlation and path-coefficient analysis for anatomical characters affecting peg strength was carried out in eleven strains of groundnut . Bundle cap length and number of xylem vessels per vascular bundle showed a significant positive correlation with peg strength . Path-coefficient analysis revealed that bundle cap length had the highest direct positive effect on peg strength whereas number of xylem vessels per vascular bundle played only a minor role directly . All the characters positively affected peg strengh in an indirect manner mostly via bundle cap lengh . All other direct effects and such indirect effects where bundle cap length was not involved were found to be unimportant . Thus bundle cap length emerged as a reliable anatomical character which can serve as a selection criterion in breeding cultivars with strong pegs to reduce harvesting losses in groundnut .
