Relationship in Various Yield Traits of Exotic Groundnut Genotypes under Moisture Stress Condition in Swat, Pakistan

Ayub Khan, Asghari Bano and Nasrullah Jan Malik

Genotype Pl.275688 produced significantly the highest pod yield (3153-kg ha ^-1) followed by variety Cina (2610-kg ha ^-1). 10 genotypes yield ranged from 2056-2861 kg ha ^-1, 52 genotypes 1056-917 kg ha ^-1, and 7 genotypes yield less than 900-kg ha ^-1. Pod yield had higher correlation with shelling percentage, 100-kernel weight and kernel pod^-1. Path coefficient analysis revealed that 100-kernel weight had the highest direct influence on dry pod yield followed by shelling percentage and pod plant ^-1. SMK percentage exhibited negative direct effect on yield closely followed by maturity, plant height and kernel pod^-1. Hence, selection for 100-kernel weight, shelling percentage and pods plant^-1 would be effective in improving the pod yield in groundnut.
