Germplasm collection

Banana

  • Evaluation of germplasm collection is in progress at Arabhavi (70 accessions), Bhubaneswar (26), Coimbatore (200), Gandevi (101), Jalgaon (90), Jorhat (84), Kannara (350), Kovvur (107), Mohanpur (124), Pusa (65) and Trichy (366). Morphological characterization has been completed for 150 accessions at Coimbatore and 102 accessions at Kovvur. Further at Kannara centre has characterized, evaluated and catalogued variability of Nendran group in Kerala and identified 10 morphotypes
Citrus

  • A total of 17 accessions at Ludhiana, 120 at Rahuri, 37 at Sriganganagar, 139 at Tinsukia, 117 at Tirupati and 614 at Nagpur are conserved. Efforts to eliminate the duplicate have been in progress.

Grapes

  • A total of 121 accessions (wild relatives belonging to different genera of family Vitaceae from different parts of Western Ghats of Maharashtra and Goa) at Pune (ARI), 17 at Ludhiana, 5 at Rahuri and 58 at Rajendranagar are being maintained. Elimination of duplicates among the AICRP centres is in progress.

 

  • Evaluation of germplasm for morphological character (5 wild species), chromosome numbers and cytogenetical relationships (53 varieties), disease resistance, nematode resistance, (13 varieties & 3 rootstocks), tolerance to flea beetle (46) has been identified. 

 Guava

  • A total of 28 accessions at Sangareddy, 52 at Ranchi, 10 at Sabour and 26 at Udaipur have been maintained, however, at Bengaluru, the total germplasm collection in guava stands at 76, including five species.

Mango

  • The total number of collections maintained are 307 accessions at Vengurle, 117 at Periyakulam, 477 at Sangareddy, 152 at Sabour, 184 at Paria, 575 at Bengaluru, 228 at Rewa, 15 at Pantnagar, 24 at Udaipur, 85 at Rahuri, 143 at Mohanpur and 745 at Lucknow. Further, a total of 350 mango accessions at Sangareddy, 88 at Vengurle were characterized as per the IPGRI descriptor.

  • At Vengurle, among the 137 accessions, 10 varieties were identified as suitable for the pulp industry based on their high yield (4.7 to 10.5 t/ha as against 2.82 t/ha in Alphonso) and high pulp percentage (76 to 86% as against 72.5% in Alphonso). 
Papaya

  • A total of 85 accessions (35 dioecious and 50 gynodioecious) at Coimbatore, 17 at Pune and 24 at Bengaluru are being conserved.

  • Morphological characterization of 80 accessions was carried out as per Bioversity International Descriptor (1988) and a catalogue on Papaya germplasm maintained at Coimbatore and IIHR, Bengaluru was compiled and released. 
Sapota

  • A total of 42 accessions at Arabhavi, 23 at Gandevi, 34 at Kovvur, 18 at Palghar and 19 at Periyakulam are being conserved and evaluated for the growth and yield attributes.
