The Directorate of Groundnut Research(DGR) at the Junagadh city of Gujarat is located at 21.31 N latitude; 70.36 E longitude; and 60 m (MSL) altitude. The DGR has been identified as the national repository of groundnut germplasm. The Centre has the following objectives related to the management groundnut germplasm.
The centre collaborates with the International Crops Research Institute for Semi-arid Tropics (ICRISAT), Patancheru, India which is the world repository of groundnut.
The characterization of collection has been done with the following objectives
The information generated through evaluation and characterization by the Centre is disseminated from time to time through evaluation catalogues to the agricultural universities and other institutes engaged in groundnut research. The Centre has been accredited as one of the National Active Germplasm Sites under the Indian Plant Genetic Resources System (INPGRS) and the activities being monitored by the National Bureau of Plant Genetic Resources (N.B.P.G.R.), New Delhi.
Variation in the primary genepool of groundnut at the morphological level is well known. Many morpho-variant types have been produced over the period of domestication. Similarly, it has given rise to continuous and discontinuous variation for agronomic traits.
This catalogue is a part of a continuous process of providing information on germplasm maintained at DGR for the benefit of groundnut researchers
The evaluation of germplasm was undertaken at the farms of DGR, Junagadh. The soil of the farm is medium-black (vertisol) and suitable for groundnut cultivation. The rainfall is well distributed with an average of 660 mm. The collection represent all four habit forms of cultivated groundnut.
