Access and management of germplasm collections: core collections for today and tomorrow (available as html version) core collections offer a tool to improve access and management of germplasmcollections, and therefore are of great interest to those who use and manage plant genetic resources. Specific germplasm collections significantly assisted in this. these collections were based on donations from existing breeding collections and on targeted collecting efforts. one of the most significant biological consequences of this progress in agriculture was the steady replacement of locally adapted, diverse traditional. Collection represents both insurance against genetic erosion and a source of tolerances to diseases and pests, climatic and other environmental stresses, improved quality and yield traits for crop improvement. table 1. germplasm holdings in the icrisat genebank, patancheru, india. crop active collection base collection accessions held in trust. Germplasm base in okra is relatively narrow. the maximum variation has been observed in the widely cultivated species abelmoschus esculentus , also called the saudanien type. the countries with the greatest collection of this group are turkey and india. 3.1 base collection. it presents the method of long term preservation of genetic variability by storing in presence of optimum conditions. for base collection, the materials are not used for distribution except with the need for replacement of material that has been lost either from active or backup collection types.

Different collection types and germplasm materials. january 2015; 10 13 march 2008 deals with the following collection types: base collection active collection security back up collection. Iv. collection also helps in saving certain genotypes from extinction. once the material is collected, it can be maintained further in the germplasm. demerits: i. collection of germplasm especially from other countries, sometimes leads to entry of new diseases, new insects and new weeds. ii. collection is a tedious job. The entire in trust germplasm collection of cultivated sweetpotato, containing 5,979 accessions, was characterized using 20 ssr markers. phylogenetic relationships were calculated revealing intraspecific relationships on a collection wide basis and identified likely genetic redundancies within the germplasm collection, especially among the.
