The branching pattern of eight sequential branching types of groundnut was studied and the contribution of each node (fruiting point) of the n, n+1 and n+2 branches (if present) to the total number of mature pods per plant ascertained. The results indicated that n+2 branches were present in several varieties and their contribution to mature pods was significant in some of them. The first three nodes of the n+1 branches contributed from 50.6 per cent (in a variety which had significantly more n+2 branches) to 88 per cent in other varieties. The results also indicated that the contribution of the late formed n+1 branches was low and the total mature pods produced from all nodes decreased with each successive (chronologically) n+1 branch in all the varieties studied. Neither the total number of n+1 branches nor the number of mature pods per node was related to the pod number or pod yield, but the total number of fruiting points from all branches showed a high correlation with pod yield and mature pod number at harvest. The results suggest that for higher pod yield it may be desirable to have only a few n+1 branches (4 or 5) but with more fruiting points on each branch.
