| dc.description | Maintenance, multiplication and characterization of groundnut germplasm· 60 wild Arachis accessions epresenting six sections of the genus Arachis: section Arachis (40 accessions); Erectoides (12 accessions) Caulorhizae (2 accessions); Rhizomatosae (2 accessions); Extranervosae(2 accessions); and Heteranthae (2 accessions) are being maintained in the field gene bank at Vridhachalam. · In the same centre, a field gene bank comprising four allotriploids (A. hypogaea cv. VRI 4 x (A. correntina X A. helodes); A. hypogaea cv. VRI 2 x A. correntina; A. hypogaea cv. VRI 2 x A. kempff-mercadoi and A. hypogaea cv. VRI 2 x A. cardenas ii); three auto-tetraploids developed from two diploid species of the section Arachis (A. villosa and A. stenosperma and one species from the section Erectoides viz. A. rigonii); 11 amphidiploids (2n=4x=40) btained through direct hybridisation between diploid wild species and tetraploid cultivated species were also being field maintained were being field maintained. · From fourteen interspecific crosses effected in kharif 2017, 64 true F1 hybrids were identified; to recover the genome of recurrent parents, 272 BC F plants were recovered from nine interspecific cross-combinations 1 1 in rabi-summer 2017-18. In kharif 2018, 18 interspecific crosses have been made introgressing the alien genes through triploid and tetraploid pathways. · Four thousand one hundred and forty-six (4146) germplasm accessions are being maintained at 11 centres. This included 60 wild accessions; 19 interspecific derivatives; exotic collection; 2834 Spanish bunch accessions; 53 Valencia accessions; 810 Virginia Bunch accessions; 74 Virginia Runner accessions; and four other germplasm accessions. · Few promising genotypes, soil-borne (stem rot and collar rot) diseases (K 1812, JL 1176, CS-319, JL-977, JL-977, HNG-10, HNG-10, ICGV- 86325, CS-19, GG-16) and earliness with fresh seed dormancy (TCGS 1157, TCGS 1694, VG 13127, VG 13149, VRI 8). | en_US |
