Guidelines for Identification, Delineation and Description of Neem Seed Sources
Exploration, identification and description/documentation of neem seed sources in its natural distribution and among land races are the first activities to be undertaken in any neem selection and improvement programme. Several schools of thought exist regarding the definition of the term "provenance". Further, the term "origin" is used by the OECD to refer to natural populations only. To avoid confusion the term "seed source" is used in this document initially to mean the exact location where se eds have been collected, with no genetical implication. When trials are established, the term "provenance" will have to be used to refer to the plants in the nurseries and trials. The present guidelines, based on a proposal by the DANIDA Forest Seed Centre, Denmark, were discussed and approved for implementation by the International Neem Network in the Second Consultation on Neem Improvement, Jodhpur, India, 28 February - 4 March 1994. The objective of these guidelines is to provide a common pro cedure for seed source exploration, identification and description. A common procedure is necessary to compare the characteristics of the seed sources and to select the seed sources which should be proposed for inclusion in the international trials to represent the different ecoclimatic conditions, and to establish a data base on seed sources identified for the species. These guidelines should be implemented by all the Network collaborators. They may also be useful to any other neem selection and improvement programme.
