A total of 163 nutmeg accessions are being conserved in the field gene bank.
A high-yielding accession with bold nut and thick mace was collected from Kakkadampoyil, Kozhikode, and added to the repository.
Evaluation of red- and yellow-mace morphotypes of Myristica malabarica revealed that red mace had higher and faster germination (41.7% and 55 days), while yellow mace exhibited slightly superior vegetative growth.
Successful budding was achieved on waterlogging-tolerant M. magnifica rootstock using IISR Keralashree and IISR Vishwasree scions.
23 clove accessions are being conserved in the field gene bank.
137 F2 progenies from Zanzibar clove × common clove were developed. Marker SaM 3999 showed Mendelian 1:2:1 segregation, confirming its co-dominant inheritance and suitability for genetic mapping.
172 cinnamon accessions are being conserved in the field gene bank.
Germplasm exploration in Meghalaya yielded 9 accessions across four Cinnamomum species.
