Abstract:
Forty-nine exotic groundnut geramplasm were screened for their physiological efficiency for future breeding program of groundnut. Our results indicated that genotype ICGS 31 had the highest harvest index of 31.43% with dry pod yield of 4556 kg ha-1 and was considered as physiologically the most efficient genotype in term of total assimilate partitioning into haulm and pod. Genotype ICGV 90120 exhibited maximum photosynthetic efficiency i.e., haulm yield of 59222 kg ha-1 with a significant lowest harvest index of 2.64 %. Significantly (p<0.05) positive correlation (r = + 0.167) was found between dry pod yield and harvest index, whereas significantly (p<0.05) negative correlation (r = -0.359) was recorded between haulm yield and harvest index.
